... Abstract Methodology and results are presented for successful and unsuccessful zonal Water Shut Off (WSO) interventions for offshore subsea gas wells located in the Norwegian Sea with open hole gravel pack completions that do not have existing packers or other mechanical zonal isolation options...

... Abstract Milling interventions can resolve a variety of issues related to downhole restrictions, and these extend beyond remediation of typical scale buildup. One such problem or challenge is that of downhole hardware becoming stuck or no longer functioning properly. In early 2020, a North Sea...

... to accomplish maximum reservoir drainage. The flex-well has been engineered to provide a low total-cost-of-ownership solution that meets global operators' current and future drilling, deployment, and production challenges. The flex-well integrates intervention solutions through a full-bore completion designed...

.... This paper will share the knowledge gained from a world's first operation, demonstrating that hydrates can be milled using electric line (e-line) tools. The operation was performed from a Vessel Fit for Purpose (VFFP) as a Riserless Light Well Intervention (RLWI) operation in the North Sea, offshore UK...

... Abstract Since the early decades, through-tubing wireline (WL) interventions have been a necessary routine of the oil and gas industry. The practice of well intervention has benefited from the evolution of WL tools on its imposed quest to keep up with the trend of increasing complexity...

... they selectively cleaned up and flowed the reservoir sections. The key objectives of the valve were to allow sequential clean-up of the reservoir section from the toe to the heel without intervention or incremental rig time. Each valve had to be remotely activated by a pressure recognition signal and also had...

... Abstract Producing well conditions in the southern region of Mexico present challenges that can benefit from the use of a newly developed intervention technology. This paper describes the development of this real-time fiber-optic (RTFO) integrated system. RTFO is used for depth correlation...

... difficult circumstances. Adopting frequent lightweight well intervention has proven crucial for subsea operators to realize the potential of 50% oil recovery. Such operations are becoming more common, but there are increasing challenges and demands as development moves toward deeper waters. To reduce...
