This paper focuses on the preparation for, and implementation of, well-control training, while highlighting the integration of people skills into curricula and what advantages operators and drilling contractors have obtained. This paper presents the design considerations, methodology, and results of two deepwater MPC operations conducted to cement production casing strings within a target operating window of approximately three-tenths of a pound. This paper presents lessons learned regarding design, testing, and installation of a completely integrated managed-pressure-drilling (MPD) control system on a deepwater drilling rig. This work focuses on the development of specific methodologies to support managed-pressure-dilling (MPD) operations implemented on real-time diagnostic software. This paper describes challenges faced in a company’s first deepwater asset in Malaysia and the methods used to overcome these issues in the planning stage.
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.
The Italian operator reported positive appraisal and exploration results from wells drilled some 10,000 km apart. This paper discusses how managed-pressure-drilling (MPD) technology led to cost savings in two wells drilled in the Hai Thach gas field offshore southern Vietnam. One common issue among operators in determining whether to install a managed-pressure-drilling (MPD) system for a campaign is the significant upfront cost. Managed-pressure drilling (MPD) has been used in Vietnam since 2007 to address a number of drilling and reservoir challenges.
Thank you for attending the SPE Workshop. This workshop was an exclusive platform for industry practitioners to share their latest experiences in Managed Pressure Drilling (MPD) and to learn from each other on improving all aspects of MPD; from initial contracting, equipment standards, supply issues, technology developments, and operational and staffing challenges in a recovering oil market. The workshop aimed not only to address the common issues affecting operators, drilling contractors, and service providers, but also to identify and discuss the differing challenges each group may be currently facing. The workshop was aimed at operators who are drilling or planning to drill MPD wells, service companies who provide MPD service offerings, and drilling contractors whose rigs may be expected to be ‘MPD capable’ prior to or during contract initiation. At the same time, the workshop may have enabled host drilling authorities to gain a better understanding of the MPD challenges and opportunities provided by today’s technology offerings.
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.
The biggest drilling company appears interested in becoming the most innovative. It is testing inventions ranging from a blowout preventer that is not hydraulically powered to power systems designed like a hybrid car. 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 new well control rule is evidence that memories of the Macondo blowout remain a powerful force for caution. Despite the rhetoric on both sides of this hot-button issue suggesting big changes, the final changes were incremental. 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.
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. More precise measurement can create a dilemma. One example is the precise fluid flow measurements used to control managed pressure drilling (MPD) systems.
