plugging and abandonment

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.

The $25 million is an initial grant from the recent Bipartisan Infrastructure Law passed last November.

Baker Hughes sees opportunity to capitalize by bundling smaller intervention campaigns.

A study of a limited number of decommissioned oil and gas wells in England found no evidence of methane leaks, including four wells found to be leaking in an earlier study.

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.
