ABSTRACT:
A method of locating hydrocarbon reserves comprising: selecting on the basis of a hydrocarbon hypothesis from a region of interest below the surface of the earth patches having probabilities of containing hydrocarbon reserves greater than a predetermined probability; defining from structural data a respective structural closure for each of the patches, each structural closure comprising an area capable of enclosing a hydrocarbon reserve and having a perimeter of constant depth substantially equal to the deepest point of the patch; determining a measure of the geometrical match between each patch and the respective structural closure; and selecting each patch having a measure of the geometrical match exceeding a predetermined measure. Particular geometrical matching methods include those relating to the height, area, volume and perimeter outline of the potential reserves.
