MWF-Geothermal™
What's MWF-Geothermal™
Every challenge requires innovation
and out of the box thinking.
While there are numerous challenges in geothermal projects, one of the main goals is to improve flow to the surface and increase surface area exposure to fluid. The use of various stimulation methods is one of the primary means of achieving these objectives in plan for the geothermal energy future.
Whether it's a hydrothermal resource or an enhanced geothermal system, using stimulation methods in geothermal prospects has had sporadic success in various projects around the world. Yet, there is hunger for innovation and project efficiency in terms of technical and economic aspects.
Most operators have traditionally completed geothermal wells in open holes, but the industry has recently realized that a constraining stimulation approach and the ability to isolate between zones can bring a lot more success in improving stimulation effectiveness, ultimately improving a project's prospects
Multi stage stimulation
Learning and applying experiences from the oil and gas industry in multistage stimulation is and will continue to be a key driver of stimulation success in geothermal prospects. As mentioned in a recent JPT (Journal of Petroleum Technology) article on multistage geothermal stimulation, the use of shale technologies will be one of the most important factors in the success of geothermal stimulation projects.
Why Seismos?
The Seismos Near-Field Connectivity Index not only quantifies the near wellbore fracture communication but gives the ability to understand stage to stage flow contributions when coupled with the measurement outputs.
In a geothermal world where analogous stimulation approaches from the oil and gas industry are applied, the Seismos technology could help:
- Better understand stage to stage complexity – ultimately understanding flow dynamics of each stage
- Apply real time changes to volumes pumped if insufficient complexity is achieved – running multiple acoustic measurements to better understand downhole response of stimulated stage
- Understand far field interaction between injection and production wells with fracture geometry outputs
- Apply the technology in any kind of pressure to temperature scenario considering that the application is noninvasive to the wells and is not dependent on pressure/temperature limitations
