Well intervention
This paper aims to establish a set of best practices for generating particle-size-distribution data from core samples.
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.
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.

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.
