Abstract
This SPE contribution provides a comprehensive explanation of the optimization of well performance through an innovative approach, refining the conventional Perforating, Wash, and Cement Technique by introducing an alternative metal-to-metal seal with a Bismuth Alloy plug. This pioneering method offers a transformative approach towards future Plug and Abandonment strategies.
The selection of the Bismuth alloy plug, rather than opting for a conventional plug barrier, stemmed from a meticulous evaluation of the specific project requirements and challenges while emphasizing the unique advantages and capabilities offered by this alternative approach. Bismuth alloy plug effectively addresses the complex and dynamic needs of the operation as well as serves as an innovative solution to sealing off the gas leaks from one of the offshore platforms in the Southeast Asia region.
The implementation of the Bismuth alloy plug has demonstrated a paradigm shift in the P&A process and integrity of the well barrier system. Not only that, it has also heralded a significant transformation by reducing the required P&A plug length.
Not only were operations expedited, but a substantial reduction in operational complexities was achieved. This transformative approach effectively addressed challenges and intricacies traditionally associated with conventional methods, streamlining the process while upholding the highest standards of safety and performance.
