Abstract: The present invention relates to a method whereby two well locations are employed to find a distribution of points where additional well locations can be found. The distribution of points form an arc defined as a trap slice. This distribution is determined in accordance with the equation An=Ae&thgr; cot &agr; wherein cot &agr; is a constant value determined on the basis of geometric data complied from existing well locations.

Abstract: A method of relating three or four producing wells in an existing fossil fuel drilling field utilizes the equation Y2+X·Y−X2=0. The independent variable X represents the distance between any two known producing wells in the field. The dependant variable Y represents a distance between a known producing well and another well location, wherein each of the known producing wells and well locations depend upon which method utilized. In one method, a first origin well can be selected as a known producing well and then a distance from the origin well to a second producing well can be determined. Utilizing the above equation, a third well location can be determined by calculating a distance Y from the origin well to the third location. This well location can represent either an existing producing well located a distance from the origin well, or a new location at which a producing well can be drilled within the existing drilling field.
