Co-optimization of carbon dioxide storage and enhanced oil recovery in oil reservoirs using a multi-objective genetic algorithm (NSGA-II)

Abstract

Climate researchers have observed that the carbon dioxide (CO 2) concentration in the atmosphere have been growing significantly over the past century. CO 2 from energy represents about global emissions. Because of impermeable cap rocks hydrocarbon reservoirs are able to sequester CO 2. In addition, due to high-demand for oil worldwide, injection of CO 2 is a useful way to enhance oil 2 storage and oil production is vital. Lack of suitable optimization techniques in the past led most multi-objective optimization problems to be tackled in the same way as a single objective optimization issue. However, there are some basic differences between the multi and single objective optimization methods. In this study, by using a nondominated sorting genetic algorithm (NSGA-II) for an oil reservoir, some appropriate scenarios are proposed based on simultaneous gas storage and enhanced oil recovery optimization. The advantages of this method allow us to amend production scenarios after implementing the optimization process, by regarding the variation of economic parameters such as oil price and CO 2 tax. This leads to reduced risks and time duration of making new decisions based on upcoming situations.

Carbon Capture, Utilization, and Storage in Saline Aquifers: Subsurface Policies, Development Plans, Well Control Strategies and Optimization Approaches—A Review

“…Meanwhile, in the absence of a direct relationship on how to achieve the technical strategy of co-optimizing CO 2 EOR and carbon storage in practice, a second group approached this difficulty by explicitly considering maximizing oil recovery, carbon storage, or a weighted combination of the two objectives using injection strategy techniques [123][124][125][126][127][128][129][130]. Furthermore, a third group of studies considers the economic aspects in the application of co-optimization of CO 2 EOR and carbon storage to honor the co-optimization policy by explicitly considering the maximization of the net present value (NPV) of the project profit or some related performance parameters [131][132][133][134][135][136][137][138][139][140].…”

Evaluating the Sealing Effectiveness of a Caprock-Fault System for CO2-EOR Storage: A Case Study of the Shengli Oilfield

“…Of the identified CGUS options, CO 2 -enhanced oil recovery (EOR) storage (CO 2 -EOR storage), which is different from the CO 2 -EOR operations traditionally used in Tertiary oil recovery, is a subject of increasing interest because of its overall advantages over other CGS options. CO 2 -EOR storage is essentially a cooptimization process of CO 2 storage and EOR designed to improve oil production simultaneously sequestrating CO 2 [5,6], which can achieve cost advantages and social and economic benefits [7,8].…”
