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.

Global spending on oil and gas decommissioning is expected to be $13 billion per year by 2040. The launch of a collaborative supply chain approach to global decommissioning offers an end-to-end solution to reduce the decommissioning burden, risk, and cost for operators in Europe, Asia, and Americas.
-
The joint venture will include work on P&A, towage of floating units, and removal of subsea infrastructure, with the ultimate goal of providing the full end-to-end process for decommissioning.
-
Many operators are taking a full-life-cycle approach to preparing for decommissioning—a shift borne of necessity amid cost and regulatory constraints.
-
With no money to be made, P&A is one area where operators can put aside their hyper-competitiveness to work together. Members of the recently formed PACE network discussed the virtues of collaboration at the Decommissioning and Abandonment Summit 2018.
-
With $102 billion of decommissioning-related expenditure forecast to 2040 in Western Europe, opportunities are ripe for the supply chain to compete with innovative and cost-effective solutions for the E&P operators.
-
The shutting in of unprofitable offshore wells and the requirements for their plugging and abandonment is attracting more attention to what is being done with the associated subsea equipment. The benefits of leaving subsea systems in place vs. recovering them are being considered.
-
A new downhole-tool-based abandonment system was developed and deployed successfully on four wells for a major operator on a field in the North Sea.
-
The supply chain is now actively working to develop low-cost solutions and is gaining valuable experience through recent projects (as documented in many recent SPE papers). Owners need to engage the supply chain early with the relevant asset data for planning and execution of decommissioning.
