IDENTIFICATION & CHARACTERIZATION OF FAULTS & FOLDS USING BOREHOLE ELECTRICAL IMAGES

DAVIS, Robert J., Schlumberger, 4900 California Ave, Suite 401A, Bakersfield, CA 93309, [email protected]

Since the introduction of Electrical Borehole Images over twenty years ago many very useful applications have been developed for this data. These include applications, which range from hand picked bed dips to fracture analysis, from thin-bedded pay determination to measuring vugular porosity, from fault geometry determination to facies analysis. These applications are made possible because of the high resolution provided by these images. The images provide the means to perform detailed high-resolution reservoir characterization at the borehole. This presentation will concentrate on structural aspects of borehole image interpretation. Fault and fold examples from different basins across the USA will be examined with an emphasis on the San Joaquin and Los Angeles Basins in Southern California.
