چکیده
This framework is constructed based on in depth understanding of the physics in the parameter space of interest for geologic sequestration of CO2, accurate and computationally efficient numerical algorithms for modeling of highly detailed descriptions of large-scale porous formations, and a flexible extensible computational framework for the optimization of real CO2 projects during both the injection and long term storage periods.

A Numerical Simulation Framework for the Design, Management and Optimization of CO2 Sequestration in Subsurface Formations
The overall objective of the project is the development of a numerical framework for the simulation of subsurface CO2 sequestration processes. The following important research areas were pursued simultaneously during this three-year GCEP project: (1) accurate modeling of CO2 trapping by dissolution and residual trapping, (2) analysis and construction of consistent and high-order adaptive implic...
متن کاملWellbore associated problems due to gas injection into non-horizontal structures
The rapid growth in natural gas consumption has increased the need for gas storage, in particular in the form of injection into depleted reservoirs. Also, CO2 sequestration into the depleted reservoirs has attracted a large attention recently. However, it is important to ensure that the injection pressure is maintained below a certain limit to avoid unsealing the cap rock or reactivation of any...
متن کاملA Numerical Simulation Framework for the Design, Management and Optimization of CO2 Sequestration in Subsurface Formations
The objective is to develop a numerical simulation framework for modeling subsurface CO2 sequestration operations. We have made significant progress on several interrelated areas of investigation. The vertical migration of CO2 plumes, which are immiscible with the surrounding brine, was investigated using high-resolution simulation. The flux function for buoyancy driven immiscible flow plays an...
متن کاملModeling and Simulation of Alternative Injections of CO2 and Water into Porous Carbonate Formations
Water alternating gas (WAG) technique is used in the petroleum industry to inject carbon dioxide (CO2) into underground formations either for sequestration or enhanced oil recovery (EOR) processes. CO2 injection causes reactions with formation brine or aquifer and produces carbonic acid, the acid dissolves calcite and changes flow behavior significantly. Modeling and investigating effects of CO...
متن کاملCapacity Investigation of Brine-Bearing Sands of the Frio Formation for Geologic Sequestration of CO2
The capacity of fluvial brine-bearing formations to sequester CO2 is investigated using numerical simulations of CO2 injection and storage. Capacity is defined as the volume fraction of the subsurface available for CO2 storage and is conceptualized as a product of factors that account for two-phase flow and transport processes, formation geometry, formation heterogeneity, and formation porosity...
