Abstract: A new tool and methodology to work, in a single-trip system, and create conduits through the casing or tubing to access the annuli, circulate out the annuli contents, accurately deliver the cement required to create the subsequent barrier. The tool and system provide a cost effective way of plugging an oil and gas well in a single trip without the need to remove in-place production casing.

Abstract: A drilling assembly is provided that includes a drillpipe, a drill bit provided at a downhole end of the drillpipe, and a pressure control module positioned proximate to the drill bit, the pressure control module including a pressure sensor that detects pressure conditions at the drill bit and automatically shut-off fluid flow within the drillpipe upon detecting a threshold pressure condition. A processor is provided at the pressure control module that communicates with a computer-readable storage medium having instructions stored thereon, to perform the operations of detecting pressure conditions at the drill bit, automatically shutting-off fluid flow within the drillpipe upon detecting a threshold pressure condition, and switching-on fluid flow within the drillpipe upon detecting an activation pressure condition.
