Managed Pressure Drilling (MPD) is an adaptive process used to more precisely control the annular pressure profile throughout the wellbore while drilling.
Converting conventional atmospheric drilling to a closed circulating loop system enables the driller to optimize mud weight and rate of penetration (ROP), more quickly detect influx and fluid loss, and discriminate wellbore ballooning and breathing. This results in lower mud product cost, less stuck pipe, and potentially fewer casing strings.
