Advancing casing drilling to deepwater: Rethinking top hole well construction
Riserless casing drilling technology in the deepwater top hole interval can provide effective mitigation and isolation of deepwater shallow hazards. This shift in deepwater well construction allows deepwater riserless casing setting depths, based on prevailing pore pressure and fracture gradients, as opposed to the established strategy of “top setting” shallow hazards.
