Measurement of fractures, slickensides and associated striae is accomplished using a state-of-the-art electromagnetic goniometer. The natural densities of the total and dominant fracture types identified (presented as 1:200 fracture density log) are calculated, and a description of each fracture with respect to its condition, origin and any fluid or mineral fill is developed.

Detailed core description is performed to characterize the different depositional facies and includes a description of lithologies, fabrics, sedimentary structures, bedding thickness, and other pertinent features. The data is compiled and computer-drafted into a lithlog format that includes other rock properties data such as porosity, permeability, mineralogy, fluid saturations, and wireline log curves if available. The vertical succession of texture and sedimentary structures help define the depositional facies of the sequence. The depositional facies define the geometry of the potential hydrocarbon reservoir. Other applications include characterization of flow barriers, lithostratigraphic and chronostratigraphic relationships from well data for integration with seismic data in the sequence stratigraphic analysis, and development of core-calibrated models for log-based lithofacies identification.
