Well intervention
Panelists at the SPE Subsea Well Intervention Symposium discussed where AI is delivering value today, where risks remain, and how engineers can best determine its usefulness.
With millions of wells having been drilled in the US since the beginning of the oil age, the land is pocked with old, unused wellbores. For most, repurposing is a pipe dream. Plugging is the best option.
This article from the SPE Research and Development Technical Section offers new insights to how the upstream industry can benefit from the emergence of quantum computing.

This technical paper describes the planning and execution of a multiservice-vessel (MSV) -based hydraulic-intervention campaign in Chevron’s Tahiti field in the US Gulf of Mexico. -
Mekers Offshore, a Zhejiang-based company, launched its first in a series of liftboats at Shanghai Bestway Dajin Heavy Industries yard in Jiangsu, China.

Intervention and workover operations can significantly affect the structural integrity and fatigue life of subsea-wellhead systems. Methodologies for wellhead-fatigue analysis have improved, but have yet to account for thermal effects along the well. This study analyzes those thermal effects.
-
A new well intervention tool can solve annular isolation problems using a proprietary epoxy sealant placed at predefined locations, which can result in significant rig time savings. Field trial results are shared in this article.
-
A refracturing campaign in the Permian yielded a production gain that allowed payback on the investment within 6–12 months.
-
A challenge in many permeable, water-sensitive, subhydrostatic reservoirs is avoiding the loss of completion fluid when completing or working over wells.
-
Well-control fluids were used during a routine overbalanced workover operation in an offshore well completed in high-permeability sandstone.
-
A challenging commodity price environment has forced operators to seek methods for sharply lowering recovery cost per barrel of oil equivalent (BOE) in unconventional plays.
-
The surge in unconventional completions has created a substantial accumulation of previously hydraulically fractured wells that are candidates for hydraulic refracturing.
-
One of the most promising targets for resource-rock stimulation in South America is the Vaca Muerta (VM) shale in western Argentina.
