Well intervention
This paper presents a novel approach to overcoming extended-reach limitations in coiled tubing interventions by using a split-string system, demonstrating measurable improvements in reach and operational speed in laterals exceeding 3 miles.
This paper describes the successful deployment of flexible coiled tubing technology in an oil-producing well of the offshore Frade field in Brazil’s Campos Basin.
This paper details a trial involving the deployment of a transportable coiled tubing (CT) unit capable of holding 30,000 ft of high-strength 2⅞-in. CT.

A refracturing campaign in the Permian yielded a production gain that allowed payback on the investment within 6–12 months. -
Well-control fluids were used during a routine overbalanced workover operation in an offshore well completed in high-permeability sandstone.
-
A challenge in many permeable, water-sensitive, subhydrostatic reservoirs is avoiding the loss of completion fluid when completing or working over wells.
-
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.
-
In a riserless-light-well-intervention (RLWI) operation in the Gulf of Mexico (GOM), a crown plug failed to release.
-
As part of a project that involves the use of four artificial islands to drill and complete more than 300 extended-reach-drilling (ERD) wells in a giant offshore oil field, several completion designs have been piloted for brownfield development.
-
Although refracturing is a topic that has gained a lot of interest, many shale producers have been sitting on the sidelines because early results did not justify the spending
-
There are considerable benefits to conducting rigless subsea well intervention from specialized monohull vessels.
