EXPANDABLE EXPERTISE First deployment of well optimisation technology in Middle East
is a key growth area for us and the first deployment of our ReLineWL in the region is a significant milestone for the business as we continue to enhance our technology portfolio to support the most complex well integrity challenges. As operators remain focused on maximising recovery efficiently and sustainably, our expandable technology is ideally placed to support this demand. “Te ReLineWL already has a proven
track record in North America and I’m excited to see this successfully deployed in the Middle East for the first time.”

xpandable technology designed to unlock greater commercial value by maximising production from existing wells has successfully been
deployed in the Middle East for the first time. ReLineWL is a one-trip, wireline-
deployed straddle system to address common well integrity issues from the well integrity and production optimisation expert Coretrax. It has been designed to deliver improved greater efficiencies for operators. Its makers claim that ReLineWL is
proven to deliver a 700% greater flow area when compared with traditional straddles, securing safety and sustainability benefits by reducing the number of onsite personnel required to complete the work. Deployed to support a major Saudi
operator, the expandable technology was brought in when water ingress on a producing well led to decreased oil recovery. Following detailed well analysis, two ReLineWL 28ft straddles were

deployed on e-line, enabling the operator to isolate several perforation intervals to shut off water production zones. Unlike traditional tools, the straddle’s outer diameter allowed the system to pass through restrictions before they were expanded and set at almost 7,000ft. Te tool delivered a large post-expansion inner diameter, providing maximum production conduit to surface over conventional options. Te well was successfully
brought back online with a 31% reduction in water production and additional oil production of 1,400bbls/day. With the requirement for surface water management also reduced the application also significantly reduced the operator’s carbon footprint. John Fraser, chief
executive officer at Coretrax says: “Te Middle East
The tool is designed to tackle common well integrity issues
UNLOCKING GREATER VALUE Te technology, which is also due to be deployed for a second time in the Gulf of Mexico, allows operators to install a patch without creating a restriction, ultimately unlocking greater commercial value from their assets. Available in various corrosion-
resistant alloy (CRA) materials, the tool can be configured to smart completion products such as autonomous inflow devices (AICDs) to enhance production by selectively eliminating gas and water production and provide a comprehensive workover solution. Te RelineWL has a high expansion ratio of 75% and is designed for stackability, creating a longer, integrated straddle to be deployed, without losing ID. Tis also allows operators to gain access below if well intervention is required at a later date.
