plugging and abandonment

This paper describes the first riserless coiled tubing services operation performed in a live subsea well and the associated improvements in efficiency, cost savings, and safety.

Across Texas, abandoned wells are erupting with chemical-infused liquid and some have created massive lakes of contaminated water. Regulators say they need more money to address the problem.

Plugging operations are scheduled to begin early 2026.

Global offshore decommissioning projects hear the starting gun in Australia and the North Sea, but will the race be a marathon or a sprint?

The money from the Investing in America agenda will be used for plugging, remediating, and reclaiming orphaned oil and gas wells in national parks, national forests, and national wildlife refuges.

The authors of this paper describe how deployment of dual-casing cement-bond-logging technology has provided critical insights in real time for decision-making on remedial jobs.

This case study investigates the reasoning behind the solidification of barite behind the casing with the aim of developing solutions for efficient casing removal and the potential use of settled barite as a barrier material.

A fundamental research study is conducted to confirm the potential usefulness of chelating agents in dispersing settled barite, emphasize the complex nature of the factors that control this process, and provide a solid basis for future studies aimed at optimizing dispersion methods in industrial applications.

A comprehensive study looks at the sealing efficiency of eutectic bismuth-tin alloy plugs in wells slated for plugging and abandonment through laboratory testing, microscopy analyses, and numerical simulations.

Companies are rushing to inject carbon into Louisiana’s ground, but will thousands of abandoned wells allow it to escape?
