plugging and abandonment

Prior to proceeding with a contract to fulfil a rigless P&A campaign for Sasol in Mozambique, BiSN designed a field trial to prove the effectiveness of its bismuth plug technology. Although the technology had been used in 19 countries by BiSN for a variety of downhole applications, it had not yet been qualified for use in Mozambique.

This paper presents a low-impact solution for well abandonment with fully electrified equipment that mostly uses grid power in an urban area.

The bipartisan infrastructure law included $4.7 to start plugging wells. But the new federal money is creating logistical and regulatory challenges, raising questions about whether the money will live up to its promise.

The bipartisan infrastructure law funding aims to address legacy pollution and spur economic growth nationwide.

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.
