An adaptive drilling process used to precisely control the annular pressure profile throughout the wellbore (IADC definition).

The session will cover an area of growing interest, given increasing concern about wellbore integrity and well control. As with other MPD systems, SMD technology offers early detection of influxes (kicks) and minimizes downhole losses to weak subsurface formations. This paper describes a number of system enhancements, including the ability to display and analyze not only the critical parameters of drilling hydraulics but also other information that allows different perspectives in considering the closed-loop system. The paper demonstrates the successful application of advanced automated managed-pressure-drilling (MPD) technologies on the Dover well close to Fort McMurray, Alberta, Canada. The development of the Kanowit field offshore Sarawak, Malaysia, requires the drilling of two subsea development wells with a semisubmersible rig.
A North Sea field development included installation of long 4½-in. To minimize overall risk, the operator planned to use managed-pressure drilling (MPD). This paper discusses an expandable-liner-hanger (ELH) system that provides liner rotation during the liner deployment and the cementing operation while providing a hydraulically energized liner-top seal upon setting.
With the US Bureau of Safety and Environmental Enforcement as a cochair of the steering committee, SPE held a 2-day summit in April to discuss the development and implementation of an industrywide safety-data sharing framework. More precise measurement can create a dilemma. One example is the precise fluid flow measurements used to control managed pressure drilling (MPD) systems. A scientist hired by federal regulators to look for ways to reduce the risk of well blowouts said it is time for the oil and gas industry to treat kicks taken while drilling the same way doctors treat heart attacks. The United States’ top offshore regulator said his agency is adopting new policies and measures to improve its working relationship with the offshore industry.
Despite the drilling industry’s shift toward managed pressure drilling (MPD) over the past half-decade, underbalanced drilling (UBD) continues to be a desirable option for many operations today. A brief primer on managed pressure drilling (MPD) and how it compares with underbalanced drilling (UBD). New technology and innovation will always be key elements for the successful development of oil and gas reserves, and continued R&D activities are essential to meet this objective.
This paper describes how a technique known as applied-surface-backpressure managed-pressure drilling (ASBP-MPD) can alleviate the limitations of conventional deepwater well control. 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. 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. On the basis of safety performance results achieved through automation downstream, an operator set out to achieve the same advances in its upstream business. Australian technology developer MezurX is touting its newly introduced flow, density, and mud monitoring system as a significantly better alternative to the widely used Coriolis meter.
