Abstract: Techniques for simulating carbon dioxide injection into a saline aquifer. The techniques include obtaining geological reference data that is correlated to a saline aquifer formation layer and establishing a set of carbon dioxide injection parameters to be tested. The simulation is computationally practical and efficient by mathematically partitioning the aquifer formation layer into a plurality of discrete partitions based on the geological reference data and utilizing fast analytical solutions to obtain relevant properties of interest within each partition. Thus, estimating carbon dioxide flow characteristics for each discrete partition of the plurality may take place based on the geological reference data and the carbon dioxide injection parameters.

Abstract: Techniques for simulating carbon dioxide injection into a saline aquifer. The techniques include obtaining geological reference data and establishing carbon dioxide injection parameters. With this data and parameters in mind, a node-based resistance grid may be established that is used to schematically generate flowlines across the saline aquifer. From the flowlines, tessellated partitions may be developed and potentially subdivided into manageable platonic shape portions. Thus, a mathematical manner of estimating flow characteristics for the proposed injection application may be simulated in a fast and reliable manner.

Abstract: A method may include identifying known parameters based on a geological model representative of a subsurface region and identifying uncertain parameters associated with the geological model based on the known parameters and field operations previously performed within the subsurface region. The operations may also include generating a simulated test design to estimate the uncertain parameters based on the known parameters by determining a sensitivity coefficient matrix at different time points for each of one or more simulated measurements associated with estimated uncertain parameters based on the simulated test design and determining a residual uncertainty associated with the estimated uncertain parameters based on the sensitivity coefficient matrix. The method may also include generating an updated simulated test design to estimate the second set of parameters based on the known parameters in response to the residual uncertainty being greater than a threshold.
