Casing/cementing/zonal isolation
An investigative study examines the use of creeping shale formations as a more durable alternative to conventional cement barriers in carbon dioxide storage wells, potentially enabling safer long-term underground carbon storage.
Thermal stimulation can accelerate the formation of shale creep barriers for long-term well integrity but only within a carefully controlled temperature window. This study identifies optimal thermal conditions for maximizing barrier performance while avoiding thermally induced shale damage.
While some idle wells may be brought back into production, many will be plugged and abandoned. This paper considers repurposing certain idle oil and gas wells by using their empty steel casing for the disposal of nuclear waste.
