Global optimization of grey-box computational systems using surrogate functions and application to highly constrained oil-field operations
Computers & Chemical Engineering 2018
This work presents recent advances within the AlgoRithms for Global Optimization of coNstrAined grey-box compUTational problems (ARGONAUT) framework, developed for optimization of systems which lack analytical forms and derivatives. A new parallel version of ARGONAUT (p-ARGONAUT) is introduced to solve…
Dimensionality reduction for production optimization using polynomial approximations
Computational Geosciences 2017
The objective of this paper is to introduce a novel paradigm to reduce the computational effort in waterflooding global optimization problems while realizing smooth well control trajectories amenable for practical deployments in the field. In order to overcome the problems…
Data‐Driven Mathematical Modeling and Global Optimization Framework for Entire Petrochemical Planning Operations
AIChE Journal 2016
In this work we develop a novel modeling and global optimization-based planning formulation, which predicts product yields and properties for all of the production units within a highly integrated refinery-petrochemical complex. Distillation is modeled using swing-cut theory, while data-based nonlinear…

A multi-scale framework for CO2 capture, utilization, and sequestration: CCUS and CCU
Computers and Chemical Engineering 2015
We present a multi-scale framework for the optimal design of CO2 capture, utilization, and sequestration (CCUS) supply chain network to minimize the cost while reducing stationary CO2 emissions in the United States. We also design a novel CO2 capture and…
Nationwide, Regional, and Statewide CO2 Capture, Utilization, and Sequestration Supply Chain Network Optimization
Industrial Engineering & Chemistry Research 2014
We design a CO2 Capture, Utilization, and Sequestration (CCUS) supply chain network with minimum cost to reduce stationary CO2 emissions and their adverse environmental impacts in the United States. While doing so, we consider simultaneous selection of source plants, capture…
