plugging and abandonment

Casing deformations are common in the south-west shale regions of China and the Middle East, where the widespread use of 5.5-in., 26- and 26.8-lb/ft casing is the norm. In these regions, the majority of frac plugs are designed with an outer diameter (OD) of 4.055 in. or slightly larger, which frequently encounter restrictions resulting in the loss of bottomhole assemb…

The funding comes from the Investing in America agenda with the goal of addressing legacy pollution.

This paper discusses housing pulverized blades mixed with Portland cement in wells considered for 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.
