... Pressure (CBHP) version of MPD with a mud weight statically underbalanced and dynamically close to formation pore pressure. Whilst drilling the 12-1/2" section of the well with statically under-balanced mud weight, to minimize the overbalance across the open hole, an influx was detected by the MPD system...

... was detected by the MPD system in Abu Roash "G" formation. Implementing the MPD assisted shut in method helped minimizing influx size. The kick was initially circulated conventionally and the MPD system was engaged during the second circulation while slightly increasing the Mud Weight. Using the MPD system...

... Abstract Abnormal variations of pit volume are a prime indicator of mud losses and formation fluid influxes. However the detection of gain and loss at the pit level can be difficult because of the transient behavior of several components in the hydraulic loop. For instance, during circulation...

... the annular hydraulic pressure profile accordingly, avoiding continuous influx of formation fluids to the surface. Any influx will be early detected, managed and safely contained. MPD may include semi-automatic or full automatic control of annular backpressure, fluid density, fluid rheology, annular fluid...

.... While drilling, these limits were ascertained within the range of 1.26 SG EMW - gas influx and 1.32 SG EMW - fluid losses. The CBHP drilling mode enabled to manage the ECD in between influxes and losses only adjusting the well head pressure to obtain instantaneous changes in the Bottom Hole Pressure...

... Abstract This paper presents a different approach in handling well control kick circulation. The existing method is to monitor the drill pipe pressure and manage the choke to hold the bottom hole circulating pressure above formation pressure while circulating the influx out of the annulus...

It is also shown that the frequency of poor bonding across shale does show a dependence on depth. It was concluded that these observations imply that fluid influx...
