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.
