Decommissioning
Shell became the first international company to operate producing fields offshore Brazil and the first to navigate the country’s complex and detailed decommissioning permitting process, which involved extensive environmental assessments, regulatory approvals, and coordinated stakeholder engagement.
ExxonMobil moves forward with the decommissioning of a 25-year-old deepwater US Gulf development.
The Ohio River Valley Institute finds operator indifference, regulatory noncompliance as chief factors in state's growing number of deserted wells.

Many of the platforms in the North Sea are late in life, operating long past their initial design expectations due to costly life-extension work. Decommissioning has moved slowly, but the low price environment is likely to accelerate the trend. -
Techniques for well-abandonment log evaluations have been studied in the Gulf of Mexico since 2012. The new methods described in this paper consist of adding nuclear sensors to supplement the acoustic measurements and introduce novel processing methods.

With the current low-oil-price environment, the cost of decommissioning is seen as a key driver for the ongoing economic viability of the basin.

The global industry is feeling the pain of the oil price plunge, but the UK feels it more acutely. Exploration drilling is at rock bottom levels, the offshore UK Continental Shelf is one of the world’s most expensive from which to produce a barrel of oil, and investment spending is expected to fall.

An ecosystem-based management program is described to assess the potential sensitivities and contribution of the platform as an artificial reef.

After initial exploration, a prospect deep in the Amazon jungle was declared non-commercial. The authors discuss how the initial project planning contributed to the decommissioning effort by means of life-cycle planning.
