Coordinate-related despiking of hydrocarbon reservoir data

A non-transitory computer-readable storage medium storing instructions executable by one or more computer processors, the instructions when executed by the one or more computer processors cause the one or more computer processors to:

• receive a plurality of datapoints of a geomechanical property of a hydrocarbon reservoir modeled by a three-dimensional (3D) grid, each datapoint of the plurality of datapoints corresponding to 3D coordinates of the 3D grid;
• for each datapoint of the plurality of datapoints, aggregate the datapoint with a noise component generated using the 3D coordinates corresponding to the datapoint wherein the plurality of datapoints is converted to a higher data precision to preserve an accuracy of the geomechanical property;
• determine that the aggregated datapoint is unique to the plurality of datapoints at the higher data precision;
• perform a transform on the plurality of datapoints at the higher data precision for Gaussian simulation;
• and
• generate, by a display device of a computer system, a graphical representation of the geomechanical property of the hydrocarbon reservoir based on the Gaussian simulation of the transformed plurality of datapoints.
