Self-adaptive differential evolution with a novel adaptation technique and its application to optimize ES-SAGD recovery process

Computers & Chemical Engineering, 2018
Abstract Differential evolution (DE) algorithm has shown good performance in many optimization problems. However, its control parameters greatly affect its performance and require many trials to determine the optimum values of control parameters for each specific optimization problem. In this paper, we present a self-adaptive DE with a new adaptation

Numerical Simulation of ES-SAGD Process in Athabasca Oil Sands with Top Water and Gas Thief Zones

All Days, 2011
Abstract Overlying top water and gas thief zones have a detrimental effect on the Steam-Assisted Gravity Drainage (SAGD) recovery process since steam penetrates into these zones which results in great heat loss.

Analysis of steam–solvent–bitumen phase behavior and solvent mass transfer for improving the performance of the ES-SAGD process

Journal of Petroleum Science and Engineering, 2015
Abstract Steam-Assisted Gravity Drainage (SAGD) has been the preferred thermal method for bitumen recovery from reservoirs in western Canada. To save energy and to be more environmentally friendly, Expanding-Solvent SAGD (ES-SAGD) is herein proposed by adding solvent into the injection vapor.
