Supervisory control for underbalanced drilling operations

Good flow and pressure control is essential for successful Underbalanced Drilling (UBD) operations. This work evaluates the use of Model Predictive Control (MPC) for integrated control of well conditions and the topside separation system during UBD. The downhole well pressure, separator liquid levels, and the separator pressure are controlled by manipulation of the rig pump, the choke, and the ...

Feasibility of Supercritical Carbon Dioxide as a Drilling Fluid for Deep Underbalanced Drilling Operations

Feasibility of drilling with supercritical carbon dioxide to serve the needs of deep underbalanced drilling operations has been analyzed. A case study involving underbalanced drilling to access a depleted gas reservoir is used to illustrate the need for such a research. For this well, nitrogen was initially considered as the drilling fluid. Dry nitrogen, due to its low density, was unable to ge...

Mitigating Supervisory-level Interruptions in Mission Control Operations

This paper introduces a new interruption recovery tool designed to mitigate the negative effects of interruptions on team supervisors in complex, mission control operations. This tool, called the Interruption Recovery Assistance (IRA) tool, provides team supervisors with a visual summary of historical mission changes, in the form of an event timeline. It also enables supervisors to gather more ...

Supervisory Control for Nondeterministic Systems Supervisory Control for Nondeterministic Systems

In this paper we present the rst results of our attempt to set up a supervisory theory for nondeterministic discrete event systems. The supervisory control problem for nondeterministic systems is speciied and motivated. A necessary and suucient condition for the existence of a supervisor is derived. Also an algorithm is presented that will automatically generate a supervisor. The results are ex...

An adaptive observer for hyperbolic systems with application to UnderBalanced Drilling

We present an adaptive observer design for a first-order hyperbolic system of Partial Differential Equations with uncertain boundary parameters. The design relies on boundary measurements only, and is based on a backstepping approach. Using a Gradient Descent technique, we prove exponential convergence of the distributed system and estimation of the parameter. This method is applied to the esti...
