ProFrac and Seismos Deploy Closed Loop Fracturing at Commercial Scale Using Direct In-Well Measurements

Thu, 12 Mar 2026 11:30:00 GMT

WILLOW PARK, TX / AUSTIN, TX - {March 12, 2026} - ProFrac Holding Corp. (NASDAQ: ACDC) (“ProFrac”), in partnership with Seismos, Inc. (“Seismos”), announced today the successful completion of their fully closed loop fracturing program, demonstrating the first real-time, intra-stage optimization utilizing in-well subsurface measurements and immediate surface actuation. The program took place in the Eagle Ford & Austin Chalk basins with a 4-well pad configuration. From February 13 to March 4, 2026, 183 stages were completed utilizing the ProFrac-Seismos leading-edge, closed loop fracturing technology.

Unlike systems that rely on offset well measurements to infer treatment well performance, this approach focuses directly on the targeted asset, the treatment well. It tracks subsurface performance through direct in-well measurements while pumping, detects deviations algorithmically, executes corrective action instantly, and validates the response within the same stage at any point. During deployment, average response time from data acquisition to automated treatment adjustment was under five minutes, with future targets below two minutes.

Industry research shows improved cluster-level fluid distribution, currently measured exclusively by the ProFrac-Seismos closed loop system, can increase productivity by up to 20%, highlighting the value of real-time measurement and adjustment. These findings align with a recent URTeC study (Craig Cipolla et al. – URTeC 4044071, 2024), which quantifies the value of achieving uniform fluid distribution across all clusters.

Intervention Methodology and Execution
The ProFrac-Seismos closed loop control logic activated when intra-stage performance deviations were detected against defined envelopes and triggers. When criteria were met, the Seismos proprietary measurement system (SAFA™) and completion logic prescribed corrective interventions, and ProFrac’s surface automation system (ProPilot®) executed coordinated adjustments during the active stage.

Primary triggers included mid-stage perforation efficiency falling below the 70% threshold or a rapid PE degradation trend detected during the active stage. In response, surface parameters adjusted intra-stage included rate adjustments to improve cluster stimulation, friction reducer adjustments to maintain stable treating pressure, and other operational parameters controlled by ProPilot®.

As a result of the closed loop optimization process, stages with intra-stage interventions experienced an additional 7% improvement in mid-stage perforation efficiency and 7.5% improvement in end-of-stage perforation efficiency compared to stages without intervention. There were no screen-outs attributable to intra-stage intervention adjustments and no additional non-productive time (NPT) introduced.

Why ProFrac-Seismos Closed Loop is a step change
Traditional frac execution often relies on treating pressure and post-job interpretation to infer downhole performance. Attempts to optimize the treatment well using offset responses face natural limitations because the treatment well lacks critical direct measurements indicative of performance. The ProFrac-Seismos closed loop changes that model by using real-time in-well measurements to guide decisions so treatments can be optimized as they are executed. Its integrated architecture is designed to scale control and learnings across stages and pads, combining real-time execution with a continuous improvement loop for design and operational decisioning.

Matt Wilks, Executive Chairman of ProFrac Holding Corp., stated, “Closed loop fracturing begins with accurate, real-time subsurface measurement, but its full value is realized when that intelligence drives coordinated surface execution. Through ProPilot® surface automation and selective chemistry integration, we are enabling true intra-stage adjustments at scale and advancing the industry’s first fully integrated closed loop fracturing architecture. We cannot change the resource itself. However, we know that as many as 35% of perforations remain closed after completion operations. Machina™, our well optimization suite, exists to help operators access that remaining 35% and maximize the productive potential of every stage.”

Controlling the Frac Outcome
“We are no longer just measuring the well; we are controlling the frac outcome,” said Panos Adamopoulos, Founder and CEO of Seismos. “Seismos, with its proprietary measurements and completion logic systems, is the core intelligence layer that makes Closed Loop Fracturing possible. By standardizing on Uniformity Index (UI) as the primary control metric, we ensure consistent, precise execution across all crews and basins, aligning real-time work with measurable production drivers.”

ProFrac x Seismos at STARS 2025

Thu, 23 Oct 2025 19:38:12 GMT

At ProFrac STARS 2025 in Fort Worth, Matt Wilks and Panos Adamopoulos introduced a major step forward for completions: Closed Loop Fracturing, the integration of Seismos’s subsurface diagnostics with ProFrac’s surface automation.

“We’ve moved from cookie-cutter stages to predefined, real-time changes based on the data we see while we’re pumping.” — Matt Wilks, ProFrac

Seismos’s SAFA (Acoustic Friction Analysis) system measures cluster uniformity and perforation efficiency using high-frequency pressure. This live subsurface data feeds directly into ProFrac’s ProPilot, which automatically adjusts surface parameters such as rate, sand, and friction reducer as each stage progresses.

“Closed loop means we don’t just measure what happens; we actively improve it while it’s happening,” said Panos Adamopoulos, CEO of Seismos. “It’s the first time subsurface intelligence is directly controlling surface execution.”

Operators can run the system in supervised mode, where engineers confirm real-time recommendations, or in unsupervised mode, where ProPilot acts automatically within safe operational limits.

According to independent operator research, even a 10% improvement in fluid distribution can deliver about $300,000 in NPV per well.

In the second half of the episode, Larry Carroll and Steven Bourgoyne explain how the Closed Loop Fracturing system operates in the field. Seismos’ acoustic analytics isolate the pressure signals that describe near-wellbore response, while ProFrac’s ProPilot instantly adjusts the surface parameters that drive stage performance.

The result is a consistent, measurable workflow that helps operators:

Detect and mitigate non-uniformity in a stage instantly
Optimize chemical and proppant usage
Achieve repeatable performance across fleets

“For the first time, engineers are seeing the rock respond as they pump,” said Steven Bourgoyne, Operations Director at Seismos. “That visibility changes how you design, execute, and evaluate every stage.” Larry Carroll, ProFrac’s VP of Engineering & Technology, adds: “Closed loop gives our teams real feedback, not guesswork. It helps us make better design calls in real time and build a foundation for autonomous fracturing.”

Closed Loop Fracturing delivers measurable improvement by connecting subsurface intelligence and surface control. Operators gain:

Visibility into cluster and perforation behavior
Control through automated real-time adjustments
Value from improved efficiency and well economics

The partnership between ProFrac and Seismos is defining a new era of data-driven, adaptive completion that evolves with every stage.

Big thanks to the Collide team for hosting this conversation and creating a platform where real innovation in energy gets shared and debated.

ProFrac Holding Corp. and Seismos to Introduce Supervised and Unsupervised Closed Loop Fracturing Across All U.S. Basins

Mon, 18 Aug 2025 13:39:50 GMT

WILLOW PARK, Texas, Aug. 18, 2025 – ProFrac Holding Corp. (NASDAQ: ACDC) (“ProFrac”) and Seismos today announced a strategic partnership for the launch of Closed Loop Fracturing, now available across all major U.S. basins.

This bold move marks the first large-scale deployment of an extensively operator-validated, real-time quality control system, enabling fully automated Closed Loop Fracturing. The system redefines how completions are measured, optimized, and scaled, and illustrates ProFrac’s relentless drive to bring its customers the best available fracturing technology, as well as ProFrac’s confidence in its quality of services, where every stage is independently benchmarked by Seismos’ technology.

“This partnership with Seismos builds on the foundation we’ve laid with ProPilot,” said Matt Wilks, Executive Chairman of ProFrac. “By combining ProPilot’s surface automation with Seismos’ subsurface intelligence, we’re delivering more control to operators through dynamic completion design that optimizes hydrocarbon recovery. It’s the next evolution of how ProFrac brings accountable performance to our customers, with Seismos acting as an independent auditor of downhole performance.”

ProFrac and Seismos are offering two deployment models to fit different operator needs:

SUPERVISED MODE : Engineers and completion teams can act in real-time using a continuous stream of validated subsurface data. This allows on-the-fly optimization of stage design, fluid placement, and perforation strategy, while the stage is still active. Every decision is based on measurements.

UNSUPERVISED MODE : For operators ready to automate repeatability, this mode allows the system to execute a set of pre-defined decisions based on real-time responses. It reduces overhead, increases operational speed, and delivers consistency at scale without requiring human intervention.

ProFrac and Seismos are already working towards full tech stack and crew-level integration. From day one, it has been designed to scale across all fleets, enabling Closed Loop Fracturing for all supermajors and leading independents.

“Seismos is the innovator who introduced the concept of Closed Loop Fracturing, and we are leading the market with the only patented, transparent, fully-vetted technology that is years ahead of the copycats,” commented Panos Adamopoulos, CEO of Seismos. “True closed-loop frac operations are built on the unbiased audit of frac performance, a capability only Seismos provides.

Save $300K on Your Next Frac

mason@seismos.com (Mason Nasizadeh) — Wed, 14 May 2025 16:50:50 GMT

5-minute read

that could save you $300K

on your next frac

With oil prices sliding, every extra minute of pump time and gallon of diesel is a line item you can shrink. Most of that “ free ” money lives in the frac vans hidden in pressure curves, friction drift, and plug surprises.

Here are five common levers and their typical payouts. Stack just two of those wins, and the $300K goal is Tuesday-level achievable.

*** All numbers come from field cases detailed in the SAFA whitepaper.

How SAFA saves

you $300K+ in Real Time

SAFA’s surface-only acoustic system “listens” to rate changes (planned or accidental) and instantly splits pipe vs. perf friction.

That live stream gives you:

Perforation efficiency & UI – one glance shows who’s choking or stealing fluid
Entry-hole diameter checks – verify shot spec without downhole tools
Plug-slip radar – catch leakers before they snowball
Treating-pressure prediction – see the pressure you should be at and fix drift instantly.

No downhole hardware, zero NPT—just actionable data while the iron’s still humming.

Seismos Founder and CEO Speaks at Greek Parliament

mason@seismos.com (Mason Nasizadeh) — Fri, 18 Nov 2022 18:08:34 GMT

Europe is strategically targeting its energy independence by leveraging a fast-track pursuit of clean energy solutions while securing safer access to traditional forms of energy generation.

On Monday Oct 31 2022, the Research and Technology Committee of the Greek Parliament conducted a meeting on the theme of Accelerating Clean Tech Innovation and Startup Entrepreneurship in the energy space.

Christos Tarantilis, Chairperson, and member of Parliament voiced that Clean-Tech startups can do more than ever to help solve Europe’s energy challenges. Such challenges would include the safe and reliable storage of renewable energy, the effective usage and management of smart energy grids and super grids, cuts in carbon dioxide emissions, the optimization of energy efficiency throughout the entire chain – from production to transportation, to distribution and to final consumption.

The CEO of Seismos, Panos Adamopoulos, spoke about Seismos' work in improving pipeline safety and in enabling natural gas & oil production efficiencies in the United States via its real-time acoustic sensing technologies. In addition, Panos described fundamental elements of the American innovation ecosystem that could eventually be applied in Greece. One of them, the "Startup America" initiative (introduced in the US in 2011) set clear priorities for the acceleration of innovation and entrepreneurship: The facilitation of partnerships between the Public and the Private sector in identifying opportunities and funding new businesses, the active support of startup companies navigating through the "valley of death" (the painful trajectory from research to commercialization), the encouragement of innovation in strategic fields of national interest (healthcare, national security, education etc.) and more.

Panos also made a reference to the critical US Bayh-Dole Act of 1980, which enabled universities, nonprofit research institutions, and small businesses to own, patent, and commercialize inventions developed under federally funded research programs within their organizations. He also said, "One proven way to speed up the invention process is to encourage groups of creative thinkers to work together (innovation clusters) in a certain field or region,where the government could invest in such private businesses.

He ended his presentation by recommending a balanced approach across the energy sector; given the continuing dependency on hydrocarbons - which realistically is not expected to change in the next decades - innovation strategies should span from both the conventional sources of energy (there is much room for optimization) to renewables and other Clean Tech initiatives.

Liberty Energy and Seismos partner up to provide real-time stimulation QC

mason@seismos.com (Mason Nasizadeh) — Wed, 04 May 2022 06:01:32 GMT

AUSTIN - SEISMOS INC, leader in advanced acoustic sensing and non-invasive monitoring systems, announced today a partnership with Liberty Energy to expand the toolset for real-time quality control of stimulation performance. Liberty and Seismos will focus on maximizing value to E&P operators by offering the Seismos-MWF™ (Measurements While Fracturing) QC and analytics system alongside Liberty’s completion services.

Through a simple surface connection, without a need for downhole equipment or offset well instrumentation, the Seismos-MWF™ system uses active controlled acoustics to directly probe the near-wellbore fracture network, providing a Near Field Connectivity Index (NFCI) for each stage. The connectivity between the fracture system and the wellbore can be an important contributor to productivity at both the well and stage level thus providing information on the quality of the fracture stimulation. The extended data collection of the Seismos-MWF™ system after each stage also allows for better fracture model calibration with pressure decline data.

This QC metric is used to benchmark in real-time every stimulated stage & well against the best producing wells of a similar geological and reservoir profile. The NFCI targets, ‘trained’ by a database of 15,000+ stage measurements and production repository, are fine-tuned for the localized acreage and continuously re-calibrated as new production data becomes available, helping Liberty customers optimize fracture designs, make changes while completing the well and improve well performance.

”We are excited to offer the Seismos-MWF™ system, a completions quality control tool that complements our industry leading portfolio of fracture optimization technologies,” said Dr. Mike Mayerhofer, Director of Technology at Liberty. “The Seismos-MWF™ system can provide a cost-effective measurement of stimulation quality in each stage and well. If NFCI falls well below target while completing the well, design or perforation changes can be made to improve NFCI on the subsequent stages.”

Panos Adamopoulos, CEO of Seismos stated, “Every stage counts. The biggest limitation to real-time fracture optimization was the lack of practical, cost-effective technologies that can be applied in every well as mainstream practice. We are thrilled to partner with Liberty, a team of experts setting the standards for engineering and customer delivery in our industry.”

Cutting edge technology to measure fracturing performance

Tue, 07 May 2019 23:44:49 GMT

This case study appeared in the July 2018 edition of E&P Magazine

A major operator in Permian Basin asked Seismos to evaluate its treatment effectiveness and completion designs for the lower Wolfcamp A formation. The goals were to identify the types of fracture systems created across the lateral, and how such systems influence production. The project encompassed a two well pad and was completed in early 2018. Each lateral was composed of approximately 45 stages and was treated with a single design.

Delivery

Seismos used its non-invasive equipment suite (Seismos-Frac™) to acquire and deliver real-time data that enabled the operator to make on-the-fly decisions, while having no impact on operations. The instrumentation consisted of a proprietary sensor and source connected on the wellhead.

By sending a series of pulses down the fluid column at specific times during the treatment, Seismos remotely interrogated the subsurface for each stage. Various wellbore properties, near wellbore fracture conductivity, network complexity, effective propped fracture length, and far-field fracture network connectivity to the reservoir were computed.

Description of Findings

In addition to Seismos’ measurements, Sonic Logs, Tracers and Geochemical data were collected. Sonic logs and Geochemical data indicated two different zones (A & B) across the lateral of the subject wells.

The pump design resulted in the development of two distinct types of fracture systems with significantly different characteristics. Seismos' measurements identified a fracture system with two-times higher near-field complexity and conductivity values in zone B, compared to the fracture system developed in zone A of the lateral.

Seismos-Frac™ technology also found that the near-wellbore complexity had an inverse relationship with the extension of the fracture network. Zone A, while a less complex fracture network, had a 32% larger average effective propped fracture length compared to zone B.

Impact on Production

Zone A covered 50% of the lateral and had significantly higher hydrocarbon content than zone B; however, zone B had an overall higher brittleness index.

Tracer data provided additional insights for the production performance of the two facture systems. Despite having significantly lower hydrocarbon content than zone A, zone B was producing over two-times more hydrocarbons on an average stage basis (tracer data, 90 days).

Lower hydrocarbon quality rock yielding higher production was attributed to the development of an enhanced near wellbore complexity system, which was accurately measured by Seismos and supported by the geomechanical rock properties.

Conclusion

Seismos-Frac™ unlocked an understanding of the stimulated fracture systems developed across the lateral, measured with precision their extended reservoir connection, and identified the near field conductivity and complexity as the dominant production drivers. Correlations with Sonic Logs, Tracers, and Geochemical data proved that Seismos-Frac™ empowers operators to enhance production contributions of each stage.

Optimizing diverter performance in real-time

Wed, 10 Apr 2019 23:50:52 GMT

This case study appeared in the September 2018 edition of E&P Magazine

Challenge

One of the ten largest US operators asked Seismos to evaluate and help improve diverter use. The project consisted of 4 wells in the Barnett play. The operator varied the volumes of diverter on each stage of the first well to evaluate how diverter impacts the development of the fracture system. The focus was on fracture propagation and the stimulation of new fractures.

Delivery

Seismos-Frac™. fracture evaluation technology was used to monitor the effects of varying diverter volumes pumped on every stage, in particular with respect to near- and far-field conductivities, reservoir connectivity, and near-wellbore complexity. Additionally, Seismos-Frac™ measured the effective propped fracture length, and monitored the wellbore condition throughout the treatment.

The Seismos-Frac™ measurements and processing were done in real time, enabling the operator to make changes on the remaining wells in the pad.

Results & Description of Findings

In stages with little or no diverters pumped, the stimulated fracture network was primarily characterized by a far-field system (Fig.I), meaning fractures with an extended connection to the reservoir. As the client increased the volume of diverters, the extension of that far field fracture system was restricted. Conversely the near field fracture region became more stimulated, increasing near wellbore conductivity and complexity. A threshold was observed past which further increasing the diverter volume affected negatively the development of the fracture system. Seismos-Frac™ identified with accuracy the "sweet spot" for the optimal volume of pumped diverter leading to the desired combination of fracture propagation and near wellbore complexity.

Impact

Based on the Seismos measurements the operator revised their completion program for the subsequent 3 wells. The revision allowed further control and management of fracture propagation and fracture network complexity, saving more than 50 pounds of diverter material on a stage by stage basis. Pumping less diverter resulted in significant economic improvements and savings.

Conclusions

Seismos-Frac™ Real-Time fracture evaluation technology allowed the operator to identify the appropriate volume of diverter to create optimum fracture characteristics.

Operators looking to optimize their use of diverters for the delivery of a target performance can use Seismos-Frac™ actual measurements to make real-time decisions, rather than relying on an ambiguous predictive software model.

Seismos was not just able to provide a binary ('works' vs. 'doesn't work') assessment but was the first technology to quantitatively measure the effect of diverters on the development of the fracture system, to identify the specific element of the fracture system that got affected, and to correlate varying volumes of diverter to specific fracture system responses.

Collaborative completions

Fri, 01 Mar 2019 00:00:27 GMT

Dale Logan, C&J Energy Services and Panos Adamopoulos, Seismos, USA, examine a combination of new technologies designed to optimize horizontal completions.

The process of optimizing a horizontal completion is typically a series of T trial-and-error adjustments designed to improve well productivity. As changes to the treatment schedule and/or perforation scheme are implemented, the effectiveness is judged by comparing the production of the new well to the production of offset wells. However, most operators agree that this optimization process could benefit significantly from additional feedback. For instance, when there is an observed difference in production between the new well and neighboring wells, is it caused by variations at every stage - or is it just a few stages that are underperforming or overperforming? It would also be valuable to be able to differentiate between productivity variations that result from changes in the completion design versus changes due to heterogeneity in the geological facies along the lateral.

There are several commercial technologies in the market that attempt to address

these questions. A few examples include hydraulic frac monitoring using microseismic, production logging and tracer logs. While these techniques have been used successfully in some instances, none have proven valuable enough to be universally accepted. The biggest challenge is that they are difficult to deploy and require a lot of planning on the part of the operator. And, because difficult deployment translates to increased expenses, most operators are willing to consider using these technologies only if they are foolproof, easy to use and provide complete diagnostic insight. Unfortunately, this is not the case with any of them, so they are relegated to exist as niche players within the shale industry.

Simple deployment delivers sophisticated data

The new Seismos-Frac™ service targets this shortcoming with a simple, noninvasive method that delivers a direct, comprehensive measurement of fracture-network properties. Seismos' approach uses a combination of ambient noise and induced, tube-wave pressure pulses to investigate the hydraulic fracture network. The measurements delivered include frac geometry (width, height and half-length), as well as near-and far-field characterizations of fracture network complexity, fracture conductivity and proppant placement. These results are produced on a stage-by-stage basis in near-real time, normally within 10 minutes of the completion of pumping. This enables the operator to review the measurements, assess the performance of a given stage and then use any learnings on successive stages.

The service is relatively affordable because it uses a straightforward installation process that is virtually plug and play. A pair of pressure transducers is installed at surface, which can typically be done in less than an hour. During the completion process, ambient noise is analyzed, and pressure pulses are sent down the fluid column to investigate the perf clusters - both before and after fracturing operations. This can be done without any interruption to the on-location completions team. As a result, this technology is particularly well suited to the industrialized environment of today's shale industry.

Collaboration is key

Seismos-Frac technology has been available in the field since 2017 and has been deployed on roughly ll0 wells to date. Early evaluations show that variability in frac geometry and conductivity from stage to stage is not only common, it is often the norm. The two most frequent causes for these variations are changes in the treatment schedule and changes in the rock properties along the horizontal well bore. To isolate the two sources of variability, Seismos encourages operators to use the Seismos-Frac service alongside C&J Energy Services' Lateral Science method. This method uses existing drilling data to evaluate changes in rock mechanics along the lateral. As with the Seismos-Frac service, the LateralScience method is delivered in an affordable, noninvasive manner, which makes the tandem technologies a natural fit into any completion workflow.

Quantitative data tells the story

In a recent well, this collaborative approach was put to the test. In part one of the test, a group of seven stages was completed using 57% less proppant and 38% less slurry than a comparable group of stages with similar rock properties (as indicated by the LateralScience facies). For the subject test group, the Seismos-Frac geometric results indicated 35% less half-length, exactly the same height and slightly higher frac width. Qualitatively, these results make perfect sense - and, since the goal was to achieve a shorter half-length (to avoid frac hits), the operator was pleased.

In part two of the test, a group of 16 stages drilled in lower-strength rock was compared to a group of eight stages drilled in higher-strength rock. The treatment schedule and completion design were held constant between the two groups. In this scenario, the lower-strength rock delivered half-lengths that were 24% longer, accompanied by far-field fracture conductivity that was 30% lower than in the higher-strength rock. Once again, this result is consistent with a lower-strength interval creating more planar fractures that extend farther from the wellbore, which distributes the proppant across a larger area and therefore produces a lower average conductivity index. Qualitatively, this is consistent with Nolte plot interpretations made on previous wells, and a quantitative value can now be assigned to the impact observed.

Better information delivers better value

The value of Seismos-Frac measurements is obvious to experts in the completion engineering domain, and this value goes well beyond optimizing the completion design. The principle applications that operators have identified as most valuable include the following:

Well-to-well optimization

New field development

This application can be extremely valuable when an operator is moving into a new area and trying to determine what works and what does not. It can provide clarity on what the fracture system looks like and what well spacing might be most appropriate. It can also provide insight into understanding correlations between stimulation designs, geology and fracture-network properties.

Sensitivity studies

Seismos-Frac measurements can also quantify how sensitive the completion is to any changes implemented in the treatment schedule. It is not unusual for operators to experiment with changes in slurry volumes, pump rates, prop pant concentrations, chemical additives, etc. Real time, quantitative feedback on how these changes impact fracture geometry and fracture-network properties affords the operator greater insight to help decide whether to adopt a new completion approach. In addition to the real time value brought by sensitivity studies on a stage-by-stage basis, they are also useful after the fact to plan for the next well.

Stage-to-stage optimization (real time)

Completion optimization

When operating in well-understood areas, the value of these measurements is realized in real time, stage-by-stage completion optimization. The original treatment schedule assumes an anticipated geometry and set of fracture-network properties. The metrics that most completion engineers use to gauge fracturing performance are pounds of prop pant per lateral foot or barrels of treatment fluid per lateral foot. When wells perform outside of expectations, they presume it is related to these metrics or that it is due to poorly distributed proppant. By monitoring each stage, compliance can be assessed, and the treatment adjusted as needed. When adjustments are required, the monitoring also provides measurements to quantify the impact of each treatment change to the resulting fracture system.

Zipper fracs

When it is time to develop the field, most operators move to pad drilling and zipper fracs. The tighter well spacing introduces issues like potential interference between wells and even frac hits. In this case, understanding the frac height and half-length is critical to ensure compliance. This allows the operator to approach the completion aggressively while avoiding excessive frac length that could be detrimental to production.

Operational assurance

In some scenarios, the focus will be on operational efficiency. By monitoring treatments on the fly, an operator can detect issues - such as leaking plugs, hydraulic communication with previous stages or even screenouts - as they develop. Providing an additional tool to detect these events enables the operator to do a better job of reacting to them and ultimately in adjusting the approach to avoid them.

Delivering results

As discussed above, this service has the potential to change how the completion workflow is performed in the field. However, to transform this potential into tangible value, the plans put together at the head office must be well aligned with what is actually happening in the field. Experience has shown that there can be significant 'value leakage' at the field level if this is not properly addressed. This is the primary driver in the alliance formed between Seismos and C&J Energy Services.

Seismos believes value leakage can be minimized by aligning its Seismos-Frac offering with a service provider that is fully vested in the success of the service. It starts at the front lines, where C&J's frac engineers are trained to understand both LateralScience and Seismos-Frac technologies - as well as how the two complement each other. On-site engineers are fully briefed on both the overarching objectives of the survey and the expected results. It is very important that the person in charge of executing the job understands completely how each specific action will impact the success of the survey. While communication with the head office is important, communication between the frac van and the Seismos trailer is vital. When this is done seamlessly, the odds of success increase significantly.

Setting the stage for the next generation

As with any groundbreaking technology, growth and adoption follow a distinct life cycle ¬¬¬–– and these are still the very early days of the Seismos-Frac offering. While the service is being embraced by the industry, it is still in the evaluation phase as operators continue to test it and become comfortable with the results they are getting. Equipment and people are being added as quickly as practical to meet the demand. Pioneering technologies will enable the next generation of engineers to make better-informed decisions and ultimately deliver more oil and gas with ever-greater efficiency. The Seismos-Frac and LateralScience collaboration provides a preview of what that will look like.
