Revolutionizing Stuck Completion Retrieval: A Novel Approach Using Cemented Inverted Tie Back Receptacles

Abstract This paper proposes an innovative method to bypass retrieving stuck completions, such as seal assemblies or packers, by utilizing an inverted Tie Back Receptacle (TBR). By doing so, significant rig time and costs associated with traditional fishing and milling operations during well de-completion will be saved. A structured methodology was developed to deploy the cemented inverted TBR. The operational sequence consisted of the following. First, cut tubing above stuck completion and retrieve it. After that, install a retrievable down hole barrier below the stuck completion and dress the top of the cut joint. Next, perform a dummy run with the inverted TBR to ensure proper seating. Then, run the inverted TBR with either a rotating liner hanger system or casing string to achieve effective isolation of the interval above the stuck completion. Finally, execute a cement job and clean-out runs before completing the well. Successful deployment of the cemented inverted TBR was achieved in three separate wells, demonstrating its efficacy in overcoming stuck completion challenges. Post-job evaluations revealed excellent isolation of the targeted zones above the stuck completion, confirming the quality of the completed wells. Compared to traditional retrieval methods, this approach showed notable improvements in terms of reduced Non-Productive Time (NPT), enhanced operational efficiency, and optimizing overall costs. Additionally, the cemented inverted TBR proved effective in achieving uniform internal diameters, thereby simplifying future well interventions. Overall, the results indicate that this innovative solution provides a viable alternative to conventional retrieval techniques, offering numerous advantages in terms of both technical feasibility and practical application. This idea presents a groundbreaking alternative to conventional practices when dealing with stuck completions. By leveraging the concept of inverted TBRs, it introduces a new paradigm shift in addressing these challenges. With successful deployments in multiple wells, this technology offers a proven solution for reducing costs, enhancing efficiency, and improving overall well productivity – ultimately contributing valuable insights to the existing body of knowledge in the oil and gas industry.
