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: Systems and methods are described herein for approximating spatial and temporal saturation and pressure of a carbon dioxide injection into an aquifer. In an example, the well is divided into segments for modeling purposes. A user provides initial input parameters for the bottom of a first segment, including an initial temperature and pressure. The initial parameters are used as input in an algorithm corresponding to the leak type. The algorithm outputs new property parameters corresponding to the top of the first segment. The new parameters are used as inputs in the algorithm in the next highest segment. This continues until all segments have been calculated. The outputs are aggregated and presented in a graphical template that includes edges representative of the output properties that connect nodes representing the well and surrounding wells and features.
