Optimizing Completions by Enhancing Near-field Connectivity and Mitigating Stress Shadowing in Real-time via Acoustic Based Workflow

In this study, a multi-well program was developed to evaluate and optimize hydraulic fracturing completions in the Delaware Basin's 3rd Bone Springs formation. Utilizing a novel acoustic pulse technology, the authors measured the Near-Field Connectivity Index (NFCI) in real-time to assess cluster efficiency, identify stress shadowing, and evaluate fluid distribution across stages. By comparing a control pad with a focused optimization pad, the study demonstrated that increasing cluster spacing effectively mitigated stress shadowing effects. Furthermore, applying far-field diverters and maintaining a minimum rate of 2.5 barrels per minute per perforation significantly improved near-field connectivity and stimulation uniformity. The real-time application of these acoustic diagnostics enabled data-driven design modifications that ultimately resulted in superior early flowback performance compared to legacy completion methods.
