Decommissioning
This paper reviews a proof-of-concept project in which surplus casing pipes were used in the fabrication of purposefully designed artificial reef structures for the enhancement of biodiversity and commercial fisheries.
ABL’s Australia unit will provide marine warranty survey services to support the first phase of Esso’s decommissioning campaign, which aims to recycle 95% of the 60,000 tons of offshore structures targeted for removal.
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.

A new regulation includes provisions related to the timely abandonment of "dormant sites," a new site classification that refers to inactive wellsites operated by solvent companies. -
Bravo is the second of four platforms to be decommissioned and removed from the Brent field, following Brent Delta in 2017. The field has produced approximately 3 billion boe since 1976.

After producing for 43 years, the Statfjord A platform will cease production in 2022.

This paper demonstrates a new way to create gas-tight seals during well abandonment, overcoming the limitations of traditional methods and reducing the operator’s liability and potential environmental impact after decommissioning has been completed.
-
Decommissioning and abandonment comes with its share of unexpected surprises, but many of those surprises could be avoided merely through better planning and care.
-
The next big wave of decommissioning and abandonment projects is set to occur in the Asia-Pacific region, and APAC’s operators are now tasked with finding cost- and time-effective ways of unwinding their huge agglomeration of wells and facilities.
-
This paper discusses studies conducted on two California offshore fields that may be abandoned in the near future. These studies examined the feasibility of repurposing these fields for offshore gas storage by using their reservoir voidage and existing pipeline facilities.
-
The outlook in the UK is a case study of the squeeze facing E&P in other basins where operators are trying to pay to sustain production with discoveries, while plugging and abandoning old wells, all paid for by the lean cash flow due to low oil prices.
-
Scientists at the National Oceanographic Centre have released a review of how marine robotic capabilities can support the environmental monitoring needed for decommissioning oil and gas installations.
-
When energy companies go bankrupt, the cleanup of their old oil and gas wells must take priority over paying off creditors, the Supreme Court of Canada ruled on 31 January.
