... with a reduction in production. The water injection also yielded high uncertainty of the downhole environment in both planning and execution phases of the drilling process, resulting in several MW adjustments when observing influxes into the wellbore. Managed Pressure Drilling (MPD) represents an advanced...

... drilling. This paper describes the effective use of the constant bottom hole pressure (CBHP) variant of Managed Pressure Drilling (MPD) in the wildcat well of X-1 to explain the successful drilling of the reservoir section, providing an incredibly narrow window of 0.08 SG across Lockhart & underlying...

... Abstract Digital Transformation through MPD Automation is revolutionising the oil and gas industry. Digital technologies provide access to higher-quality information about operations performance and allow companies to react quickly when unexpected events occur due to weather or equipment...

... Abstract Managed pressure drilling (MPD) technology is a widely accepted technology for wells with narrow pore- pressure/fracture-pressure (PP/FP) gradient window. Whilst MPD is often associated with high capital expenditures (CAPEX) that further erodes the project economics especially...

... challenges, a hybrid solution combining Underbalanced (UBD) and Managed Pressure Drilling (MPD) was applied. UBD was used to characterize the reservoir in terms of pressure and productivity index to ultimately enhance productivity by eliminating formation damage. MPD was used next to continue drilling...

... Abstract In pursuit of efficiency and well construction cost optimization, the oil and gas industry demand continuous improvements and constant evolution of the service providers’ hardware and software, including Managed Pressure Drilling (MPD) technologies. Recently deployed in the Caspian Sea...

... Abstract While drilling highly depleted gas reservoirs with a very narrow drilling window, Common drilling methods like utilizing loss of circulation pills, wellbore strengthening materials and managed pressure drilling (MPD) are being used in several reservoirs, yet it cannot be successful...

.... The uncertainty in determining the pore pressure adds another challenge as the mud weight must be higher than the expected pore pressure. Managed Pressure Drilling (MPD) addresses these challenges by enabling determining the pore pressure while drilling and adjusting the Equivalent Circulation Density (ECD...

... size and location. MPD was proposed to utilize a mud weight that minimizes the differential pressure between the producing and injecting layers within reservoir which mitigates the drilling problems related to high differential pressure. The game plan was to start drilling the depleted zone...

... on a previous well drilled in the same field (Well-A), the drilling team has identified Managed Pressure Drilling (MPD) a key enabling technology that can help in mitigating the drilling hazards of (Well-A). A task force was formed with the MPD service provider to plan the MPD system deployment on Well-B...

.... On the other hand, drilling through Marrat section encounters drilling difficulties such as mud loss and differential sticking in depleted middle Marrat layers juxtaposed to high-pressure layers of upper intervals. Keeping the above problems in mind, Managed pressure Drilling (MPD) was applied first time...

... &thermos-dynamic flow simulation using MPD with CBHP mode: – Kick tolerance requirements – Kick intensity – Safety margin including choke margin for well control event and minimum surface pressure loss caused by MPD equipment and piping – Static mud weight for calculating kick...

... Abstract Managed Pressure Drilling (MPD) is an increasingly common technique in narrow margin HPHT wells. However, MPD is sometimes viewed as a 'bolt-on' technology, only added after much of the planning work has been carried out and all other alternatives have been exhausted. By this stage key...

... techniques are needed to develop Shakal field potential. In case of Shakal-2 and Shakal-3 exploration wells, the 12-¼" and 8-½" hole sections applied Managed Pressure Drilling (MPD) technique and Microflux ® control system technology to reach planned objectives and reduced a combined 15 days of drilling...

.... The circulation mode can be selected between Manual, Constant Bottomhole pressure (CBHP), Reference depth and Kill sheet. In order to simulate MPD, the CBHP mode is selected, since it is a variation of MPD. Using this mode, the choke pressure during kick circulation is calculated automatically to keep...

... out being drilled conventionally and had to be changed to managed pressure drilling (MPD) using the rig choke. For the final two wells, the client chose to use constant bottomhole pressure (CBHP) MPD with an automated choke from the start of the section. For each well, a historical analysis...

... 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...
