Offshore Drilling and Completion

Measured-pressure approaches (drilling, cementing, and completions) have offered much promise for some time but have been slow to reach widespread application. A spate of technical developments, deployments, trials, and applications, however, recently has pushed measured-pressure drilling (MPD) and its nuanced variants to their full potential as viable well-construction methods.

Development of fully integrated drilling, control, and management systems, along with surveillance and data-processing enhancements, have brought the idea of fully functional real-time measured-pressure management to reality. Increasing experience, design feedback, validation, and enhancements are making a number of derivatives of the approach widely applicable. As well as the drilling operations themselves, experience has increased to include all aspects of the well-construction process, including both cementing and completion running operations. Increasing equipment automation and surveillance and control systems is now providing confidence and accuracy with well-calibrated models of in-situ behavior. Additionally, the real-time management of operations creates a feedback loop that allows continuous improvement to be at the heart of execution and learning.

As broader industry experience and case history volume increases, the ability to deploy and use these approaches will provide additional flexibility to operators as they develop increasingly challenging formations and tight or complex pore-pressure fracture-gradient profiles and windows. Measured-pressure techniques and variants now appear to be coming of age, and wider application will continue to enhance and enrich their functionality. Continued automation, data management, and personnel training and experience will support the continued and increasing deployment of these approaches.
