Drilling
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.
Conflict‑driven price gains may be offset by higher costs, supply‑chain risks, and a limited appetite for new drilling activity.
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.

I am encouraged that we, as an industy, continue to refine and tweak our practices to solve zonal-isolation and cementing challenges in every well environment in which we work. As cementing techniques are improved, so, too, are the cement-evaluation methods and work flows. -
Against the background of a low-oil-price environment, a redevelopment project was launched to give a second life to a shallow, depleted, mature offshore Congo oil field with viscous oil (22 °API) in a cost‑effective manner.
