Customer challenges
- An underground storage engineering company specializing in accurately determining the boundaries of various well fluids, including brine, diesel, and gas, within fuel storage caverns faces a critical challenge
- The accuracy of the data was essential for calculating the stored fuel volume within the cavern
- The company aimed to identify fluid interfaces and potentially assess the density and purity of each fluid by using a downhole multipoint sensor array
Expro Excellence
- Expro deployed its innovative multipoint sensor array in a water well to evaluate its effectiveness before full-scale deployment of the systems
- The objective includes comparing the new measurement system's data with existing methods, investigating issues related to fluid ingress and leakage,and ensuring the integrity and reliability of the storage facilities
- Expro offered a cost-effective solution compared to fiber optic cable
- The trial successfully met the primary objective, providing confidence to the client in deploying the solution at the full scale
- The full deployment of the multipoint sensor array provided fluid density measurement that was previously unavailable, aiding in the identification of fluid ingress sources and giving better well and reservoir insight
Value to client
- Real-time data: Validated fluid level measurements using Expro's multipoint sensor array and confirmed the accuracy of customer-provided data
- Valuable insights: Customer can view fluid movement within the well
- Removed uncertainties: Identified and provided evidence of two areas within the "static" well where fluid flow was occurring
- Understanding: Enhancing understanding of fluid dynamics in the storage system
