Abstract

This comprehensive review of oil and gas production and potential from pre-Silurian reservoir rocks of North America, Africa, Asia, and Australia indicates a major frontier for petroleum exploration. About 90 percent of the production comes from well-known fields in the midcontinent and southwestern United States, but recent discoveries in Libya, Morocco, and Algeria have achieved significant production; pre-Silurian marine rocks in Asia and Australia are virtually untested. At present, pre-Silurian production of oil and gas constitutes only 3.4 percent of the world production. Rock-age itself should be no barrier; the writers believe the petroleum industry has suffered from a 'basement complex'--a fear of being in rocks that are too old and too deep--which has inhibited development of pre-Silurian rocks.
