Dimensionality reduction for production optimization using polynomial approximations

Computational Geosciences 2017

B. Beykal Christodoulos A Floudas E. Gildin Fani Boukouvala N. Sorek

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…

ARGONAUT: AlgoRithms for Global Optimization of coNstrAined grey-box compUTational problems

Optimization Letters 2016

Christodoulos A Floudas Fani Boukouvala

The algorithmic framework ARGONAUT is presented for the global optimization of general constrained grey-box problems. ARGONAUT incorporates variable selection, bounds tightening and constrained sampling techniques, in order to develop accurate surrogate representations of unknown equations, which are globally optimized. ARGONAUT…

Data‚ÄźDriven Mathematical Modeling and Global Optimization Framework for Entire Petrochemical Planning Operations

AIChE Journal 2016

Baoguo Zhao Christodoulos A Floudas Fani Boukouvala Guangming Du Hongwei Liu Jie Lie Xin Su Xin Xiao

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…
