... riser gas. This study is limited to the situation in which a rig has an MPD system installed, and the integrated riser joint is in the riser, but could have the RCD sealing assembly installed or not. When it is not installed, the operator can install it before performing such activity. The Riser Gas...

... Abstract MPD operations have been consistently performed in deep water well construction for +10 years. Some even may advocate it has become commonplace. The consideration of being a fully dominated technology can lead to a false sense of safety. Even though MPD techniques unlock unattainable...

... Abstract Extending the MPD engineering analysis into lower-completion string designs in addition to the MPD approach during drilling operations has proven critical in mitigating operational challenges in a multi-well campaign offshore Ivory Coast. This location is known for depleted reservoirs...

... Abstract MPD for reservoir characterization in green field applications is often seen as vital for providing operators with valuable information about the reservoir's physical properties while drilling. This aspect of Managed Pressure Drilling (MPD) in mature fields is not often a driver...

... Abstract This work discusses the experience and results of generating a rig-specific riser gas handling (RGH) procedure based on previous project experiences and the IADC Riser Gas Handling Guidelines developed by the Riser Gas Handling sub-committee of the IADC Underbalanced Operations...

.... However, it is worth describing to provide better context on the drilling operation. These overburden sections are summarized as follow: Abstract Kvitebjørn is a gas and condensate field in the Norwegian sector of the North Sea which was discovered in 1994. Kvitebjørn produces from Middle Jurassic...

... Abstract Managed Pressure Drilling (MPD) is becoming a common practice in the drilling industry and is getting more utilized and accessible to even the smallest operators. Albeit, we often see a need for a more fundamental understanding of MPD, where it should be used, what its limitations...

... by maintaining a positive RCD pressure (20-50 psi). As drilling progresses deeper, a higher loss rate zone / vugs or caves might be encountered, and the static loss rate can increase substantially. In this case. the annulus could be displaced to LAM (underbalanced mud) and become a standard PMCD operation...

... Figure 1 Conceptual IME plot showing the different operational zones. Figure 2 Potential zones of IME expansion when accounting for RGH. Figure 5 Liquid flow rate at MGS during RGH circulation of two kick volumes (18 and 40 bbl) at three intensities in WBM system (top...

... and the communication protocol required when making connections. Again, prior to the start of the MPD well sections, a second round of on site and operationally focused training as both a refresher and more specific focus on procedures was completed with the wellsite drilling team. Initially, the operational window...

... it is managed, especially with a long reservoir interval thickness exposed. Even with detailed fingerprinting data to understand the expected flowback signature for these operations, it can still be challenging to detect an influx during a conventional connection due to the effects of flowback, drain back...

... replacement of the bearing assembly. RCD Monitoring System Requirement The challenges encountered in managed pressure drilling operations and maintaining the closed pressurized loop have led to the development of condition monitoring equipment to understand the factors causing the rotating component...

... control operations from an influx can take days. On the contrary, a false negative will force drillers to perform secondary well control procedures that may lead to loss of circulation if excessive and unnecessary pressure is exerted on the formation. MPD allows for a systematic approach to identify...

.... It achieved bottom hole pressure (BHP) control within a 0.1 - 0.2 ppg operational window. This paper will discuss how, operationally, this 1-man per shift MPD crew communicated with the rig and operator personnel, delivered accurate pressure control on connections, performed dynamic formation integrity tests...

... Abstract With the current uncertain situation regarding the stability of oil prices in the world, operators have been pushed to develop their available resources in a cost-effective way. Lately, there has been increased interest in the application of Coiled Tubing Drilling, especially...

... Abstract Drilling the Point Pleasant-Utica formation in the Appalachian Basin has posed challenges to most operators, especially in Western Pennsylvania. A recent well drilled in this region demonstrated that with proper buy-in from the Operator, Constant Bottomhole Pressure (CBHP) Managed...

... has the ability to actively control the rig, performing a series of commands to space out, stop the top drive, shut down the pumps and shut-in the BOP. Abstract Digitalisation and automation can account for massive efficiencies in wells operations. Managed Pressure Drilling (MPD) and Automated...

... and precise on-site coordination between CML and gravel pack operations. In the target reservoirs, the margin between the pore and fracture pressures is too small to place gravel packs using conventional methods. CML was identified as an opportunity to resolve this problem. A primary design phase goal...
