... Abstract Drilling horizontal wells in shallow and poorly consolidated reservoirs in deepwater scenarios involves risky operations due to the narrow mud weight window. Risks include severe drilling fluid losses, wellbore instability, and fault reactivation, which, in the worst case, may connect...

.... This impressive uptake in offshore MPD applications is due in part to a requirement to drill in greater water depths, through depleted zones or reservoirs and into narrow or relatively unknown equivalent mud weight (EMW) drilling windows. As evidenced by the greatly increased cost of drilling today s prospects...

... is displaced with 10.2ppg synthetic oil-based mud (SOBM) while drilling out the shoe track and mud weight is increased to ~10.4-11.2ppg prior to drilling through a sloughing Paleocene shale section. The 12-1/4 section is directionally steered utilizing a point-the-bit rotary steerable system in conjunction...
