Derivative-free trust region optimization for robust well control under geological uncertainty
Silva, Thiago Lima; Bellout, Mathias; Giuliani, Caio M.; Camponogara, Eduardo; Pavlov, Alexey (Peer reviewed; Journal article, 2022)A Derivative-Free Trust-Region (DFTR) algorithm is proposed to solve the robust well control optimization problem under geological uncertainty. Derivative-Free (DF) methods are often a practical alternative when gradients ... -
Introducing Approximate Well Dynamics into Production Optimization for Operations Scheduling
Hulse, Eduardo O.; Silva, Thiago Lima; Camponogara, Eduardo; Rosa, Vinicius R.; Vieira, Bruno F.; Furtado, Alex Teixeira (Journal article; Peer reviewed, 2020)Most of the literature on short-term production optimization concerns the computation of optimal system settings for steady-state operations. Such methodologies are applicable when the scales of time are faster than reservoir ... -
Network-Constrained Production Optimization by Means of Multiple Shooting
Silva, Thiago Lima; Codas, Andrés; Stanko, Milan; Camponogara, Eduardo; Foss, Bjarne Anton (Journal article; Peer reviewed, 2019)A methodology is proposed for the production optimization of oil reservoirs constrained by gathering systems. Because of differences in scale and simulation tools, production optimization involving oil reservoirs and ... -
Optimal preventive policies for parallel systems using Markov decision process: application to an offshore power plant
Machado, Mario; Lima Silva, Thiago; Camponogara, Eduardo; de Arruda, Edilson; Ferreira Filho, Virgílio (Journal article; Peer reviewed, 2023)This work proposes a Markov Decision Process (MDP) model for identifying windows of opportunities to perform preventive maintenance for multi-unit parallel systems subject to a varying demand. The main contribution lies ...
