plugging and abandonment

Advantages for conversion of nonactive oil and gas wells to geothermal wells include deferred plugging and abandonment costs, safety and environmental concerns, and potential energy production.

Research team pushes toward a framework for managing millions of abandoned oil and gas wells.

With global decommissioning activities forecast to reach $100 billion through 2030, early planning for it could go far in helping to minimize risk and associated costs.

The multiyear, $20 million-plus contract is for a well abandonment campaign in the Balmoral area in the UK central North Sea.

The authors discuss a modified ultrasonic-cement-analyzer (UCA) vessel that allows assessment of slurry sealing performance under representative downhole conditions while running otherwise standard UCA equipment.

This paper compares the sealability performance of an expanding geopolymer with that of an expansive commercial cement in terms of the shear bond strength and the hydraulic bond strength at curing conditions of 25℃ and 34.5 bar.

We invite you to join the P&ATS to help our industry thrive, as the expectations from the stakeholders get tougher and a lot more “deep” wells drilled in support of geo-energy supply approach the end of their useful life.

Federal infrastructure law gives states financial incentive to remediate orphan wells.

Bob Pearson shares his thoughts on the repurposing or abandonment and decommissioning of wells that are unlikely to be repurposed or pose an environmental risk with emissions into the atmosphere or aquifers.

Houston-based startup Cemvita Factory uses its hydrogen-producing microbes downhole to considerably lower the cost of hydrogen production.
