Customer Challenges
- Our clients asset featured a selection of multi-zone water injection wells where there is some uncertainty around which zones were taking the injected fluids
- Additionally, the client sought to quantify fracture growth during injection to mitigate the risk of uncontrolled fracture extension, thereby assuring the long-term performance of the reservoir
- To address these challenges, the client selected Expro's Distributed Fiber Optic Sensing (DFOS) Intervention solution to provide high-confidence insights to optimize injection strategies and safeguard reservoir integrity
Expro Excellence
- Expro converted an existing Mechanical Slickline Intervention package into a DFOS Intervention Package, delivering a compact, cost-effective, and operationally efficient solution
- The surveillance program featured:
- A baseline survey
- A step rate injection test
- A warm back survey
- Expro’s DFOS eXtract® data processing software enabled rapid data analysis, with processed data transmitted to an off-site analyst for near real-time interpretation and analysis
- The data was integrated and visualized using Expro’s QikView™ software, providing a clear and actionable insight of dynamic well performance
Value to Client
- The complete well surveillance capability of the DFOS Intervention technology was used to gain actionable insight regarding the injectivity profile of the multi-zoned well
- The conversion of an existing Mechanical Slickline Intervention package into a DFOS Intervention Package enabled our client to gain real-time well insights while minimizing footprint and intervention costs
- High Injectivity was confirmed in two of three zones during the step rate test, with the third zone exhibiting a rate dependant zero to low injectivity characteristic
- Analysis of the DFOS data determined fracture growth during injection, with this insight being used to mitigate against the risk of uncontrolled fracture extension
