Abstract: Methods, systems, and computer-readable media for assessing porosity and water saturation cutoff values for hydrocarbon volume estimation are described. The techniques can include determining a plurality of water saturation and porosity value pairs for locations regularly-spaced along at least one borehole. The techniques can further include plotting the plurality of water satoration and porosity value pairs on a graph and representing a plurality of percentiles of the estimated maximal hydrocarbon volume on the graph. The techniques can also include causing the graph to be displayed to a user, such that the user can visually observe a combined sensitivity to porosity and water saturation cutoffs values. The user can take various actions based on the display.

Abstract: A method of predicting a subsurface property value includes obtaining a plurality of geospatial datapoints; selecting a plurality of modelling areas of the geospatial datapoint, wherein each modelling area overlaps at least a portion of a neighboring modelling area; determining a local model for each modelling area; assigning a local model value for the subsurface property to the local cells based on values of the plurality of geospatial datapoints within the modelling area; determining a global model for the plurality of geospatial datapoints; assigning at least one global model value for the subsurface property to each global cell of the global model; predicting a calculated value of the subsurface property at a selected location based at least partially on the global model value of a selected global cell of the global model; and planning a subsurface well based at least partially on the calculated subsurface property.
