The ever‐increasing quest to identify, secure, access, and operate oil and gas fields is
continuously expanding to the far corners of the planet, facing extreme conditions toward …

Most model-based control and estimation techniques put limitations on the structure and
complexity of the models to which they are applied. This has motivated the development of …

Automated managed‐pressure drilling (MPD) is a method to enhance downhole pressure‐
control performance and safety during drilling operations. It is becoming more common to …

The problem considered in this paper is that of controlling downhole pressure during oil and
gas well drilling, with a particular focus on handling gas kicks leading to two-phase gas …

Modern approaches to process monitoring, optimization and control promise enhanced
robustness and performance through the merger of process knowledge encoded in …

Drilling into offshore deep water, high-pressure high-temperature reservoirs is a very
challenging process. The most important task in these drilling operations is to control …

The problem of heave-induced-pressure fluctuation during drilling is considered. The
surge/swab pressures created by the vertical motion of the pipe can excite resonances that …

This paper presents a modification to L 1 adaptive control that allows for disturbances
entering at the output and application of this control strategy to Managed Pressure Drilling …

This paper presents a constrained model predictive control scheme for regulation of the
annular pressure in a well during managed pressure drilling from a floating rig subject to …

This paper presents a constrained finite horizon model predictive control (MPC) scheme for
regulation of the annular pressure in a well during managed pressure drilling from a floating …
