# Decommissioning

The UK’s Net Zero Technology Centre looks to pave the way for new well P&A technologies to be tested, trialed, and brought to market quickly.
Decommissioning decision makers often need to determine the best and most practicable options for pipelines, flowlines, and power cables, including leave-in-place strategies or removal. This study presents results from several evaluations using advanced methods to support the determination of options.
These four technical papers provide an overview of how facility decommissioning is addressed these days, including a case study in east Asia and a discussion of what to do with pipelines, flowlines, and umbilicals to preserve the environment—should they stay, or should they go?

• One of the last oil facilities in state waters on the path towards full decommissioning slated to begin in 2022.
• The complete paper presents the results of an investigation into the creep behavior of North Sea shales and their ability to form effective annular barriers.
• Final lab testing has been completed and field trials of the ultrahigh expansion bridge plug will begin by the end of this year.
• The Bureau of Safety and Environmental Enforcement approved the conversion of the Lena compliant tower platform into an artificial reef under the bureau’s Rigs to Reefs program.
• Plugging and cleaning up the open oil and gas wells in Texas could cost companies and taxpayers as much as $117 billion, according to a new report. • New research released by Columbia University's Center on Global Energy Policy and Resources for the Future estimates that a federal program to plug roughly half a million abandoned and so-called "orphaned" oil and gas wells could create as many as 120,000 jobs and reduce pollution. • In its push to boost deepwater production, Petrobras is aiming to launch a leasing tender to build an FPSO described as Brazil’s largest-ever oil platform. Decommissioning work begins in the Campos and the Sergipe-Alagoas Basins. • The Hydrogen Offshore Production project identifies an alternative to decommissioning by providing reuse options for offshore infrastructure. It aims to prove the feasibility of decentralized hydrogen generation, storage, and distribution to provide a bulk hydrogen solution. • The COVID-19 disaster and a catastrophic fall in oil prices could leave the state on the hook for billions in environmental cleanup costs if oil and gas companies go bankrupt during the health crisis, New Mexico's top land official says. • Even before the global pandemic impacted markets, decommissioning work in the North Sea region was expected to increase. Global decommissioning projects could reach$42 billion by 2024.
