Real-Time Minimization of Mechanical Specific Energy with Multivariable Extremum Seeking
(Peer reviewed; Journal article, 2021)Drilling more efficiently and with less non-productive time (NPT) is one of the key enablers to reduce field development costs. In this work, we investigate the application of a data-driven optimization method called ... -
Search Space Reduction for the Thermal Unit Commitment Problem through a Relevance Matrix
(Peer reviewed; Journal article, 2022)Given the combinatorial explosion related to the operation decisions in the thermal unit commitment problem, this paper presents a new strategy to reduce the search space and to start the multi-modal optimization process. ... -
Simulation of stress hysteresis effect on permeability increase risk along a fault
(Journal article; Peer reviewed, 2019)CO2 sequestration projects will in the coming years include both aquifer and depleted oil and gas field sites, with different stress paths and history. Stress changes and stress concentration effects on faults will have ... -
A Space Reduction Heuristic for Thermal Unit Commitment Considering Ramp Constraints and Large-Scale Generation Systems
(Peer reviewed; Journal article, 2023)This paper expands the research around a recently proposed method to reduce the search space region for thermal unit commitment problems. The importance of such techniques comes from the combinatorial explosion regarding ... -
Use of concentric hele-shaw cell for the study of displacement flow and interface tracking in primary cementing
(Peer reviewed; Journal article, 2021)We present our new designed concentric Hele-Shaw cell geometry with dynamic similarity to a real field wellbore annulus during primary cementing, and then, the results of displacement flow of Newtonian and yield-stress ...
