MPD/UBD
This paper describes the path to implementation of full casing rotation during primary cementing jobs.
MPD was used to successfully drill through a pore pressure ramp and address a well-control event in conjunction with conventional methods.
Digitalization and automation successes are here to stay. Instead of making small incremental steps in well construction operations, allowing disruptive shifts can lead to tangible performance gains in efficiency, safety, and well integrity.

The influx-management-envelope (IME) concept is an advanced, innovative way to assess influx conditions in managed-pressure-drilling (MPD) operations, offering an improved tool for the decision-making process. -
An early commitment to integrate MPD into an HP/HT drilling operation can make MPD more than just an enabling tool and turn it into a performance tool that offers significant operational benefits.

This paper details the operational effects of closed-loop drilling to demonstrate its ability to yield operational-process-safety improvements and cost savings over conventional methods.
-
Managed-pressure drilling (MPD) challenges the conventional drilling paradigm, along with drilling-contractor and operator policies and standards. Conventional drilling practices for connections, flow checks, tripping, and well control have been long understood and standardized.
-
In the past, most wells have been drilled using conventional methods, but the landscape is changing as economic pressures have forced the drilling industry to refocus.
-
One common issue among operators in determining whether to install a managed-pressure-drilling (MPD) system for a campaign is the significant upfront cost.
-
The unique properties of deepwater formations pose significant challenges to the capabilities of conventional drilling rigs. Using automated drilling equipment, including MPD, efficiency and cost savings can accompany safety.
-
This paper describes experiences, challenges, and approaches to solving the problems related to creating an advanced early kick-detection system suitable for floating mobile offshore drilling units.
-
The operator of an offshore jackup rig in the North Sea required safe and efficient deployment of the completion string without killing the well during tripping.
