Customer challenges
- A prominent new consortium was working with major industry players to test a closed loop “Advanced Geothermal System” (AGS) at an indoor test facility at the Oklahoma Energy Innovation Center at the Hamm Institute for American Energy in Oklahoma City
- Expro was contracted to provide an innovative solution to engineer a track for tubular running services (TRS) operations inside the test facility, with up to 15 copper wires running along the OD of the casing
Expro Excellence
- A modified approach to normal TRS was required to operate within a controlled environment
- The heaters and copper wiring running up he 9 5/8” casing presented the biggest challenge, as we had to run slips around the casing without causing any damage to the outer cables or heaters
- Expro engineered a minimal footprint, custom track and tong hanger solution to present the Expro’s hydraulic power tong to the tubulars without requiring an overhead lifting device, which
- greatly enhanced the safety and efficiency of the operation, and allowed careful make up th casing before installation in the test wellbore
Value to client
- With Expro’s successful reconfiguration of our TRS suite of equipment, the consortium was able to safely handle and set up the 9 5/8” casing with heaters and copper wires
- Assuring that the casing and associated jewellery were installed in the test well without damage, the consortium was able to monitor the completed AGS test well under specific, controlled conditions
- The lessons learned from this successful test well will enable the consortium to continue testing and proving new geothermal technologies, as well as embark on site-specific pilot projects with other consortium members to maximize the value that these Geothermal wells can deliver to market, enhancing returns on their renewable energy investments
