Closed-loop predictions in reservoir management under uncertainty
(Journal article; Peer reviewed, 2017)Uncertainty is a major challenge in reservoir management. To take the uncertainty into consideration, optimization can be carried out over a set of scenarios. Most approaches on reservoir management under uncertainty ... -
Exploiting wired-pipe technology in an adaptive observer for drilling incident detection and estimation
(Peer reviewed; Journal article, 2021)We deploy an adaptive observer recently developed for general hyperbolic partial differential equation (PDE) systems to detect and diagnose various drilling incidents. The well is modeled by a distributed PDE which, contrary ... -
Simulation of heave-induced pressure oscillations in Herschel-Bulkley muds
(Journal article; Peer reviewed, 2017)Heave induces pressure oscillations when drilling offshore from floating rigs. A time-domain model is proposed to analyze and predict such pressure oscillations. The model considers the coupled dynamics of the mud and the ...
