Managed Pressure Drilling (MPD)
Drilling process optimization
The goal – to prevent the inflow of well fluids into the borehole and safe displacement of potential influxes out of the well by utilization of specialized equipment without breaking the drilling process.
MPD technology allows to control pressure profile through the wellbore at any given depth, determine the actual gradients of formation pressures and fracture pressure while drilling, maintain the constant pressure downhole in the wells with a narrow drilling window (allows to drill longer sections), allows quick increase of downhole pressure, without the need for heavier mud displacement in the well in the unstable hole sections. MPD has much more advantages, to reduce the NPT and increase efficiency and safety of the drilling process.
