plugging and abandonment

One of the newest ways to plug and abandon wells and patch casing leaks involves an alloy that flows like water.

The authors describe a study analyzing a comprehensive data set recorded in casing-cemented sandwich sections and recovered during the abandonment of a well in the Valhall Field.

Managed-pressure drilling has been associated as a technology used only on problematic wells and only as a last resort. However, when integrated at the beginning of operations as part of a comprehensive well plan, it becomes a performance-enhancing solution for any type of well classification, including development, directional, multilaterals, and horizontals.

The authors seek to eliminate the need for pressure testing in the evaluation of annular creep barriers by qualifying the barrier using only cased-hole log measurements.

The DOI guidance explains how states can apply for the first $775 million in grant funding available this year under the Bipartisan Infrastructure Law to create jobs cleaning up polluted and unsafe orphaned oil and gas wellsites across the country.

TAQ Energy, an oilfield abandonment service company, and Engage Mobilize announced a partnership to develop a cloud-based operational and financial platform.

The US government has made more than $1 billion available to qualified states. The program is part of the recently passed infrastructure law.

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.

The impact of orphan wells, both on the environment and on tightening budgets, is a growing concern in the industry. Boom times result in a vast uptick in wells drilled. In bust times, when companies disappear, the liability outlook for these probes gets murky and federal and state governments start looking for answers.

Airborne drones with magnetometers have worked well in trials and are ready for more widespread use, potentially revealing thousands of previously unknown wells.
