Methods and computing systems for determining gas storage capacity in a reservoir

A computer program for determining gas storage capacity in a subsurface area of interest (“AOI”), the computer program comprising a non-transitory computer-readable medium comprising code configured to:

• receive a stratigraphic forward model representing at least a portion of the AOI, the stratigraphic model being calibrated using one or more geo-parameters associated with the AOI;
• receive at least sensor data associated with the one or more geo-parameters of the stratigraphic model from one or more sensors deployed about the AOI;
• determine boundary condition data for the one or more geo-parameters of the stratigraphic model based on the sensor data;
• impose computational bounds on the one or more geo-parameters of the stratigraphic model using the boundary condition data thereby initializing the stratigraphic model for the AOI;
• execute a simulation operation on the stratigraphic model by varying one or more values of the one or more geo-parameters within limits constrained by the computational bounds imposed on the one or more geo-parameters to generate a multi-dimensional simulation dataset for the AOI;
• resolve the multi-dimensional simulation dataset to generate a report associated with the AOI, the report comprising one or more of:
• one or more multi-dimensional images that visually indicate one or more gas storage capacities of the AOI as a function of one or more time-steps, or
• textual data indicating a quantification of the one or more gas storage capacities of the one or more multi-dimensional images;
• in response to selecting, using the computer processor and based on the report, a first time-step comprised in the one or more time-steps, generating, on a graphical interface, one or more of:
• a first visual representation of a volume of space comprised in the AOI for storing gas at the first time-step comprised in the one or more time-steps, or
• a first quantifier comprised in the textual data that corresponds to a quantification of the volume of space comprised in the AOI.
