Reservoir rocks have much lower electrical conductivity if they are saturated with oil rather than salt water. This is the principle, well known from borehole logging, which is exploited in Sea Bed Logging.
Halliburton fracs more wells than any other company. It is therefore hardly surprising that a Halliburton company, Landmark, is developing cutting edge tools to optimize the drilling of successful wells in unconventional reservoirs.
Historic drilling and production data can be used to enhance exploration strategies focused on stratigraphic and subtle combination traps.
