Abstract:
1. A method for horizon binning for an area of interest comprising: a. identifying an attribute file derived from a member of the group consisting of: b. merging the attribute file with attribute values with a second horizon file, wherein the second horizon file is a member of the group consisting of a time file with time values and a depth file with depth values, wherein merging the attribute file with the second horizon file forms a merged file; c. identifying an area of interest of the merged file forming an identified area file; d. identifying a time range for a time horizon file or a depth range for a depth horizon file over which to perform analyses on the identified area file; e. proposing a theory that the identified area has at least a portion that is contiguous between a hydrocarbon area and a water-bearing area; f. binning the identified area of interest using a member of the group consisting of file with a first value, wherein the first value is a member of the group consisting of time values and depth values, wherein binning the merged file with the first value forms a plurality of bins in specified increments; g. computing a calculated value for each bin forming a computed value, for at least one member of the group consisting of h. creating a plot by plotting the computed value relative to the first value for each bin; i. viewing the plot to ascertain if a discontinuity would correspond to a fluid contact; j. using a discontinuity with a water reservoir model and at least one hydrocarbon reservoir model to confirm the theory; and k. using the discontinuity to determine a boundary between the water reservoir model and the hydrocarbon reservoir model and the corresponding water reservoir and the corresponding hydrocarbon reservoir for an identified area.
