plugging and abandonment

Equinor cites confined gas behind casing and calibration issues in investigation of Troll field well control incident.

Despite a 2.8% drop in liquefied natural gas exports in 2025 because of lost market share in China, Australia anticipates a 2026 rebound as new North West Shelf capacity comes online. Meanwhile, East Coast operators brace for a tsunami of wells entering the decommissioning pipeline and potential energy shortfalls necessitating LNG imports.

This study illustrates the new capabilities, tailored for carbon-dioxide storage applications, of a modeling framework that provides a quantitative, risk-based assessment of the long-term integrity of legacy plugged and abandoned wells.

The North Sea Transition Authority has published its first table identifying 13 operators that are behind schedule in decommissioning their inactive North Sea wells.

The Ohio River Valley Institute finds operator indifference, regulatory noncompliance as chief factors in state's growing number of deserted wells.

This paper presents a comprehensive literature review of perforate, wash, and cement techniques that compares new methods with traditional ones and uses field cases and computational fluid dynamics to find the most cost- and time-effective practices without sacrificing safety.

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?
