    摘要: 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; and 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.
