Combining high-definition images of individual perforations with accurate measurements of entry hole geometry, PerforationVA provides the most complete in-situ perforation evaluation available. Our unrivalled data analysis capabilities deliver unique insights for both conventional and unconventional perforating applications.

Hydraulic fracture specialists design limited entry treatments to mitigate the unwanted effects of perforation erosion. When engineered changes are made to treatment parameters, frac specialists need clear information to understand the effects of these changes, the impact on fracture propagation and placement of proppant volumes. Through the integration of qualitative and quantitative erosion assessments, PerforationVA provides a complete picture of the fracture treatment and a cost-effective diagnostic tool to evaluate success.

EV’s range of highly-optimised, industry-leading downhole video system, combined with in-house developed, proprietary dimensioning software, efficiently and accurately measures the effect of perforation erosion. By uniquely pinpointing erosion at individual perforations, PerforationVA allows proppant placement to be confirmed, not just at the stage or cluster level, but by each and every perforation in the treated interval. This unique capability far exceeds the resolution provided by conventional distributed acoustic methods, and at a fraction of the operating cost. Results from individual perforations are combined to define proppant distribution at cluster and stage-level, efficiently identifying under, over and effectively treated zones.

With unrivalled operations and analytics experience, EV provide a unique advantage in measuring the success of plug and perf hydraulic fracturing operations. Whether new wells or re-fracturing operations, PerforationVA provides the definitive assessment required to enable effective decision-making for hydraulically fractured wells. For conventional perforating applications, PerforationVA allows perforation specifications to be measured where it matters: at the point of contact with the reservoir. Meaning surface-based testing, and models to extrapolate results to downhole conditions can finally be tested in-situ, providing a new level of understanding of perforation efficiency and production performance.
