In the current drilling environment, the industry is facing greater pressure-related challenges while developing mature and unconventional fields, both on land and offshore. Additionally, there is greater focus on improving the feasibility of tight pore-pressure/fracture-gradient wells, safety, and increasing efficiency. The challenges that are present while drilling these wells with these tight conditions, are solved by a technique called Managed Pressure Drilling (MPD), which is defined by the International Association of Drilling Contractors (IADC), as an adaptive process used to control the annular pressure profile throughout the wellbore. Among the MPD techniques, it is found one that maintains the pressure at the bottom of the well constant, and in order to face this challenge, Drillmec S.p.A.
