Well intervention
This paper aims to establish a set of best practices for generating particle-size-distribution data from core samples.
This paper documents the testing, integration, and field deployment of a metal expandable packer used as an openhole toe isolation plug in a deepwater well under high-pressure, high-temperature conditions.
As the pace of new discoveries slows and high-quality prospects become harder to find, oil companies may need to rely more heavily on mature fields to maintain production and support future supply.

A company is selling a new well testing tool designed to be a cheaper, simpler way to do fiber optic sensing, and then it fades away. -
BP has seen enormous payoff from a program to intervene in underperforming subsea wells in the Gulf of Mexico.

The case history presented in the complete paper describes the performance of an acid-fracturing intervention in an HP/HT well in which this intervention was the last procedure considered to evaluate the productivity of a Marrat Formation well.

A coiled-tubing selective perforating and activation system that transmits critical downhole data and measurements in real time is enabling well interventions that previously could not have been executed.
-
Development of a new polymer composite that degrades via hydrolysis in hot water or brine holds potential for use in structural applications for intervention-less downhole tools.

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.
