Title: Examples of Electrical Logs in Fractured Rocks: ABSTRACT

Author(s): R. D. Ford, Milton E. Loy

Article Type: Meeting abstract


A discussion of electrical logs in fractured rocks is of interest in this symposium because, to the geologist and engineer, not only does a fractured rock reservoir require a different interpretive technique, so also does the electric log. Inasmuch as the electrical characteristics of basement rocks, fractured shales, and cherts may all be similar, all are referred to as fractured rocks.

Slides are shown illustrating the following areas:

Santa Maria cherts   Elk Hills chert and shales
Edison schist        Newport Beach--fractured shales
Maricopa shales      Wilmington schist

These illustrations show that there is apparently very little correlation between Previous HitresistivityNext Hit and production. This Previous HitapparentNext Hit lack of correlation may be attributed to the fact that the physical characteristics controlling Previous HitresistivityTop are not necessarily the same as those which control production.
