.... The proximity of some wells to communities and freshwater bodies heightened environmental sensitivity, necessitating advanced Plug and Abandonment (P&A) techniques and meticulous risk assessments. A phased approach was implemented as follows: Pre-Work Phase: Detailed surveys and custom wellhead...

... immobilization incidents. The plan included a multi-basin 10 well conventional coiled tubing plug drill-out campaign, in which traditional CT surface data was combined with a downhole telemetry bottom hole assembly (BHA) and a three-phase flowback meter. All three data sources were combined and displayed...

... achieved remarkable success, completing 21 runs in total. The operations included scale and sand cleanout, wellbore integrity diagnostics using a multi-finger caliper and camera in memory mode, plug retrieval and setting, and memory injection logging. The campaign maintained an impressive 98.6% operating...

..., we achieved the demanding geometric extension of the M-Bubble plug that achieved the required ID delta to provide an effective platform in an application where more traditional solutions had not been viable. Our paper will delve into the intricacies of this project, detailing the well challenge...

... Abstract A super major International Oil Company operating in Asia Pacific was using a hydraulic workover unit (HWU) running drill pipe singles as part of their Plug & Abandonment (P&A) program. A portion of the work scope involved conveying a service packer to act as both a barrier...

... Abstract Post-fracturing plug removal is an ever-evolving challenge in unconventional fields, with an upward trend in average lateral lengths necessitating the deployment of additional fracturing plugs. Within the subject area, high wellhead pressure (WHP) coupled with the presence of Hydrogen...

... Abstract Subsea well intervention is challenging because of the high rig spread rate and the global scarcity of vessels capable of handling such operations. In plug and abandonment (P&A) activities, where there is no production upside from the intervention, operators are interested...
