Patent ID: 7363158

Claim:
A method for creating a stratigraphic model comprising the steps of: a) obtaining a core from a wellbore, the wellbore having an interval of stratigraphic interest including a cored interval from which the core was obtained; b) examining the core and creating a graphic core description from the core; c) obtaining wireline data, including a borehole image, over an interval of stratigraphic interest which contains the cored interval; d) processing the wireline data into an interpretable borehole image; e) comparing the detailed graphic core description with a portion of the borehole image corresponding to the cored interval to create a catalogue of geologic image facies; f) comparing the borehole image to the catalogue of geologic image facies to create a preliminary pseudocore for the interval of stratigraphic interest; g) examining the interpretable borehole image and the preliminary pseudocore to create a master pseudocore interpretation; h) obtaining a second wireline data from a second wellbore covering a second interval of stratigraphic interest, the second wireline data including a second borehole image; i) processing the second wireline data into a second interpretable borehole image; j) comparing the second borehole image to the catalogue of geologic image facies to create a second preliminary pseudocore for the second interval of stratigraphic interest; k) examining the second interpretable borehole image and the second preliminary pseudocore to create a second master pseudocore; and l) correlating between the first and second master pseudocores of the wellbores to create a stratigraphic model.
