Abstract:

A method for creating a stratigraphic model is provided. A core is obtained from a wellbore and a detailed graphic core description is created. Wireline data, including a borehole image, is obtained for a cored interval corresponding to the core and processed into an interpretable borehole image. The core description is compared with the interpretable borehole image to create a catalogue of geologic image facies. The borehole image from the entire interval of interest is compared to the catalogue to create a preliminary pseudocore description. The interpretable borehole image is interactively examined and compared with the preliminary pseudocore description to create a master pseudocore interpretation. A second master pseudocore is developed for a second wellbore. A stratigraphic model, and subsequently a reservoir model, may then be created by correlating between the master pseudocores of the first and second wellbores.
