... cement slurry Equivalent Circulating Density (ECD) will fracture the formation while the cement is pumped into the open hole. Hence, the Managed Pressure Drilling (MPD) method was used to drill hole sections lower than 13 ⅜” casing as well during the cementing job and running in hole with 9 ⅝” casing...

... formations), as well as drilling fluid losses in highly permeable sands and the possible presence of natural fractures. To drill the reservoir section of the Sagari 7D well, managed pressure drilling (MPD) and managed pressure cementing (MPC) techniques were applied as a solution to address all those...

... the well due to insufficient operating window to drill ahead. After a year of suspension, a new drilling approach using a statically underbalanced mud weight (MW) in combination with an Automated Managed Pressure Drilling (MPD) system was introduced as the best solution for drilling into the well...

... of low annular velocity. The pressure increase in the wellbore due to the cuttings loading was sufficient to cause losses to the formation. A new managed Pressure Drilling (MPD) system, developed for drilling subsea wells, uses proven subsea mud pumps from the Riserless Mud Recovery (RMR) system...

... theoretical and physical explanations for the multiple phenomena observed during an actual well control event, and their impact on the interpretation of the well behavior. Moreover, this paper provides useful insights on the additional capabilities offered by the usage of the Managed Pressure Drilling (MPD...

.... The campaign saw a dramatic increase in non-productive time (NPT) due to differential sticking and loss of circulation as well as difficulty in working over these wells conventionally. Subsequently, Saudi Aramco started a campaign in late 2012 to workover these wells utilizing managed pressure drilling (MPD...

.... However, to mitigate identified operational challenges, the 7-in. liner depth was adjusted to cover the high pressure section of the reservoir, thus isolating the weaker reservoir zones at well total depth. Managed pressure drilling (MPD) was deployed to drill both sections to reduce the overall...

... and losses. 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...

...1. INTRODUCTION The MPD definition is documented as follows: Managed pressure drilling (MPD) is an adaptive drilling process used to precisely control the annular pressure profile throughout the wellbore. The objectives are to ascertain the downhole pressure environment limits and to manage...

... 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...

... an optimal and reliable drilling method that would address the challenges of pore pressure uncertainty in a safe and cost-effective way. The first step was to implement Managed Pressure Drilling (MPD) to control over-pressurized zones and determine the more suitable mud density to control the well...

..., a steady bottom hole pressure within that window was deemed critical to successfully drill to the section target depth. The application of Managed Pressure Drilling (MPD) was selected to drill the narrow drilling window and has resulted in being able to successfully drill to the targeted depth without...

... outweigh the reward of increased production. The effective variation of static and circulating densities must be minimized. A major project in the Gulf of Mexico posed such a problem. Managed pressure drilling (MPD) was adopted as the solution to manage a tight hydraulic window and effectively drill...
