The Williston Basin digital stratigraphic data files contain stratigraphic correlations including formation tops, lithologic picks, and significant intraformational markers for large areas or basins. These digital data files expedite the search for oil and gas by providing explorationists with a consistent regional geodigital (stratigraphic) framework necessary for the integration of other disparate subsurface data types such as drill stem tests, cores, perforations, stimulations, plugging methods, casing programs, mud programs, drill bit programs, production information, and many others. Explorationists need this depth-related information to begin detailed geologic analyses and mapping of hydrocarbon trends.

     Experience in regional stratigraphic studies, tested scientific methodologies, and commitment to superior quality have resulted in the largest commercial library of interpreted, regionally-correlated digital stratigraphic data files in the Williston Basin. These Williston Basin digital stratigraphic data files contain information on 16,413 wells. Forty-eight Paleozoic and Mesozoic intervals and markers were correlated in 15,043 of these wells which have the relevant geophysical logs necessary to make correlations. Locations and basic header information are also provided for the remaining wells.

Internally Consistent Correlations

    These Williston Basin digital stratigraphic data files were developed by a scientific team experienced in the regional

stratigraphy of the Williston Basin to ensure an internally-consistent system of picking tops and markers.

Rigorous Error Checking

     The data have been subjected to rigorous error-checking routines using computer-generated statistics and contour maps. Williston Basin experienced geologists also hand-contoured maps to check for regional consistency and compatibility with the stratigraphic models of the area.

Corrected Elevation and Location Data

    All reported well locations were evaluated using the header data off well logs compared to vendor data. Elevation data from logs was cross-checked with vendor data and, where necessary, with 71/2 minute topographic maps.

Client Tested Files

    The Williston Basin digital stratigraphic data have been client tested and designed for optimum quality and applicability.

Personnel Invested

    A 17-member geologic team contributed a total of ten people-years worth of work to the Williston Basin digital stratigraphic data file.
