Paper Number: SPE-208786-MS
... Abstract Traditionally, well control systems have been entirely reliant on a single human reliably and accurately detecting an influx and shutting-in the well.  The human condition means the driller can be distracted, or unexpectedly influenced by extraneous factors. Over-reliance...

... the surface, leading to a major well control risk. Integrated Pressure Activated Valve (PAV) with Autonomous Inflow Control Valve (AICV) offers a unique solution to manage well control risks, allowing safe deployment of lower completion in such challengeable situations. The PAV module is mounted in series...

... Automating a well control process is a much simpler task than managing pressure during an MPD application. Some MPD systems today are managing bottom hole pressure within a 50-psi window. Several of the transient effects that must be calculated and managed during MPD are not in play during a well...

... the first optimization iteration is used to construct the snapshot matrix. The results demonstrate how refining the control approximation with more decision variables per well lead to better NPV values, but with a higher computational cost. The best NPV was achieved using the highest refining level...
