AB - ABSTRACT: The following regions are pointed out as new territories with confirmed oil and gas bearing units: Shabva Depression (Yemen) with four oil and 8 gas formations detected; Lianos region (Colombia and part of Venezuela); Indian Ocean basin near the South African Republic the south of Mossel Bay with high production rate oil and gas formations discovered; the southeastern section of India in the land and ocean basin adjacent to Andhra Pradesh. Oil and gas bearing resources of newly surveyed regions of the Atlantic shelf near the U.S. coast and Bahamas, and some Central American states (Belize, Honduras, etc.) is not confirmed. Mesopotamian and Central European oil and gas provinces, and the Arctic-Norwegian section are distinguished among the old producing regions for extraordinary results. Gigantic oil formations in Venezuela, large formations in Mexico, terrestrial and marine areas of the Sirte (Libya), Suez and the Matrukh desert (Egypt), and oil and gas provinces as in the water basins of Guinea Bay (Nigeria) and Gabon are discovered. Petroleum bearing deposits in northwestern Africa and adjunct areas of the Atlantic Ocean (Morocco, Mauritania, Senegal, Gambia, Guinea-Bissau, Guinea) as well as in the margins of the Philippine area of the South China Sea, Cook Inlet in Alaska, the Mediterranean Sea near Spain and France and some other regions are not confirmed.
