Challenge
In the fall of 2021, an O&G customer encountered a significant challenge at their production site in the Permian Basin. Water and H2S (hydrogen sulfide) heel production were impeding the production of hydrocarbons, resulting in decreased efficiency and increased operational costs. The challenge was to find an effective solution to isolate the water and H2S, minimizing the need for costly surface cleaning while maximizing hydrocarbon production.
Solution and Achievement
The Coretrax solution involved deploying the ReLine MNS 4.25” x 5.5”. This choice was made after careful consideration due to its shoeless patch design and the incorporation of additional safety factors through a running tool. This design offered a distinct advantage over competitors' products, ensuring the safety and reliability needed for this critical operation.
The project required a comprehensive approach. The customers' operator ran logs and conducted well testing before initiating the liner deployment. A team of four Coretrax personnel was deployed to ensure the operation's success. Several cleanout runs were conducted to confirm that the well was ready to receive the liners. In total, over 5,000 feet of ReLine MNS 4.25” x 5.5” were deployed across two installations.
The key outcome of this project was the successful isolation of water and H2S, which minimized the costs associated with cleaning H2S on the surface. This not only improved operational efficiency but also led to a quick payback period, which highlights the financial benefits of the solution.
The customer expressed their satisfaction with the installation. They found that the ReLine MNS 4.25” x 5.5” worked better than expected and noted that there were no significant delays in the running and setting of the liner. This case study highlights the importance of proper preparation for liner deployment, as emphasized by the client.
