A reduced random sampling strategy for fast robust well placement optimization
(Journal article; Peer reviewed, 2019)Model-based decision-making in oilfield development often involves hundreds of computationally demanding reservoir simulation runs. In particular, well placement optimization under uncertainty in the geologic representation ... -
At-bit estimation of rock density from real-time drilling data using deep learning with online calibration
(Peer reviewed; Journal article, 2021)We present a novel streaming learning approach, utilizing a deep neural network (DNN) to learn from data available during operation to estimate at-bit density using drilling parameters. Since every wellbore is different, ... -
Black-oil minimal fluid state parametrization for constrained reservoir control optimization
(Journal article; Peer reviewed, 2016)We propose to solve a black-oil reservoir optimal control problem with the Direct Multiple Shooting Method (MS). MS allows for parallelization of the simulation time and the handling of output constraints. However, it ... -
A dynamic model of two-phase flow for simulating gas kick and facilitating model-based control in drilling operations
(Peer reviewed; Journal article, 2021)A low-order two-phase dynamic flow model for drilling operations with gas kick is developed. The purpose is to enable fast and robust simulation of the behavior and propagation of influx gas in the bore hole, and the effects ... -

Reservoir Characterization in Under-balanced Drilling with Nonlinear Moving Horizon Estimation with Manual and Automatic Control Conditions
(Peer reviewed; Journal article, 2020)This paper discusses the state estimation of the Under-Balanced Drilling (UBD) system in the presence of parametric uncertainties. During this process, the production indices of oil and gas from the reservoir into the well ...
