... Abstract Integrated Riser Joints (IRJ) have become a key component of deepwater Managed Pressure Drilling (MPD) operations. They enable the surface MPD system to be integrated with the riser, allowing for safe and fast installation and retrieval despite complexities. Deepwater MPD integrated...

...Conclusions The detailed analysis of MPD versus conventional drilling in the Permian Basin, with a focus on the WolfCamp-D (Cline) wells, underscores the numerous advantages of MPD. These advantages include significant time savings, the use of lighter and cost-effective mud systems...

... Figure 1 shows an example deepwater well. The RKB depth to mudline is 1,100 m. It is intended to drill the 12 1/4 in. section (out of the 14 in. intermediate casing) to TD using MPD. A 9 7/8 in. high collapse casing is then planned to be run to TD and cemented using MPC. Without loss...

... technologies. Constant Bottom Hole Pressure (CBHP) variant of Managed Pressure Drilling (MPD) was identified as an enabling technology to help mitigate the risk of drilling the reservoir through the presence of highly pressure depleted sands and wellbore cooling risk mixed with virgin pressure stringers...

... The main MPD equipment consists of the following: Rotating Control Device (RCD) – the first major difference in doing MPD relative to conventional drilling is converting the open to the atmosphere system to a closed loop one. This is made possible by the installation of the RCD above the rig...

... Abstract While drilling through the Permian Zechstein Group, North Sea operators can encounter a permeable overpressured interval which cannot be statically stabilized with conventional methods. An operator proposed drilling with Liner (DwL) in combination with managed pressure drilling (MPD...

... contractors. The use of advanced drilling simulators provides a new environment where drilling crews can not only be trained in how to react and implement the well control procedures, but also allows the implementation of new technologies such as Managed Pressure Drilling (MPD) in highly sensitive...

... Abstract Managed Pressure Drilling (MPD) enables safer operations and reduces non-productive time and thus provides the opportunity to reduce well costs. Many operators however, are not fully embracing the opportunity offered by the technology, due to strict regulatory requirements...

... enters the BOP stack. MPD For MPD operations, the trip tank pump does not have sufficient discharge pressure to work with a pressurized closed loop system, and the well often does not accept a static condition with returns open to atmospheric pressure. In this case, the back pressure pump...

... Abstract As the industry-wide adoption of managed pressure drilling (MPD) continues, the recent emergence of reliable continuous flow systems (CFS) are right on its heels, offering many parallels in wellbore pressure control and protection. The question then presents itself—does continuous flow...

As with all conventional casing designs, the resulting pipe has limited capacity to withstand increased burst and collapse loads associated with extending hole sections if the opportunity arises.

Abstract Managed pressure drilling (MPD) has heralded an era of accurate and precise downhole pressure control. Not only can today’s MPD systems...

... Abstract With the increasing use of Managed Pressure Drilling (MPD) to mechanically control bottomhole pressures for drilling narrow mud-weight windows, little consideration has been given until recently to integrating drilling fluid design and MPD operations for a specific application...

... wells) for the upper limit, both estimations were done at the top of the reservoir. The drilling window for Managed Pressure Drilling-MPD was validated by determining the Bottom Hole Pressure where both, an influx from the formation and fluid losses occurred. These values were later used to establish...

... Abstract This paper presents the control system, the preparations and some test results for a managed pressure drilling (MPD) operation at the Gullfaks oil field in Norway. The control system was developed with the objective of maintaining the bottom hole pressure (BHP) within a narrow pressure...
