... the challenge of uncertain pore pressure. MPD static pore pressure testing (SPPT) with reducing surface back pressure (SBP) applied is performed to update the pore pressure ramp until max pressure depth where regression trend is expected. During regression trend, LWD FT is performed to acquire pore pressure...

... be conducted at any chosen depths of interest, aiding in verifying a real-time lower boundary of the drilling window as well as defining the minimal surface back pressure (SBP) to be applied during MPD operation. A defined MPD dynamic formation integrity test (DFIT) / MPD dynamic leak off test (DLOT) can...

... In MPD drilling, the wellbore is a pressurized system. BHP can be controlled by applying surface back pressure, in addition to hydrostatic of the mud column and annular friction pressure. ( Oseme et al.,2016 ) (2) BHP = P hydostatic + P annular friction + SBP Pore...

... with a hydrostatically underbalanced spacer & cement slurry while applying dynamically controlled surface back pressure through MPD set up. MPC was the chosen approach to mitigate the risks when cementing the 9-7/8in liner in a hydrostatically underbalanced condition and applying surface backpressure (SBP) using...

... Pressure (SBP) through the use of a Rotating Control Device (RCD) and an Automated MPD Choke Manifold. CBHP applies precise surface back pressure into the annulus by means of automated MPD system to maintain the annulus pressure when circulating and static. CBHP is achieved during pipe connection when...
