This abstract first appeared for US patent application 18455847 titled 'CAPROCK ANALYSIS METHODS AND SYSTEMS
Original Abstract Submitted
A method of analyzing a caprock of an aquifer includes determining, using a laboratory measurement device, a threshold hydraulic gradient of the caprock at which brine flows vertically in the caprock. The method further includes determining a breakthrough pressure of the caprock, wherein the breakthrough pressure reflects a difference between a COpressure in the aquifer and a brine pressure in the caprock. The method further includes calculating, via a computing system that includes one or more hardware processors, an effective breakthrough pressure of the caprock based on the threshold hydraulic gradient and the breakthrough pressure, wherein the effective breakthrough pressure accounts for non-Darcy flow of the brine within the caprock.
