The Blake Plateau is a deeper "trough" that lies about 140 miles 

 off Georgia and Florida in water depths of between 1,500 feet and 6,000 

 feet. 



The Southeast Georgia Embayment and the Blake Plateau trough are 

 not as favorably looked upon as potential petroleum provinces as other 

 areas because of the relatively thin sequence of sediments in the first 

 case and the deep water conditions in the second. 



The Gulf of Mexico is divided into two zones geologically separated 

 into an eastern province with relatively simple geologic structures and 

 a western province of complex structures involving faulting and intrusion 

 of salt beds. Hydrocarbon potential extends from inshore to depths over 

 1,200 feet. 



The Gulf of Mexico has been extensively developed and is the source 

 of 15 to 20 percent of the Nation's petroleum production. At present, 

 the known prime areas of the Gulf have been leased, particularly during 

 the 1970-1975 period. The remaining years of the 1970' s will see less 

 exploratory drilling and increased development drilling in the Gulf. 



The Pacific Continental Shelf includes the following three sectors: 

 Southern California, central and northern California and Washington- 

 Oregon DCS sectors. The Southern California PCS is a complex geologic 

 structure which includes islands, banks, ridges, submarine canyons and 

 basins. The basins lie in water depths varying between 1,900 feet 

 and 6,200 feet. 



The Central -and Northern California CCS is a region that contains 

 six structural basins that are extensions of onshore basins. These 

 basins include from south to north: the Santa Maria, Outer Santa Cruz, 

 Bodega, Point Arena, and Eel River basins. 



Oil has already been produced in the onshore Santa Maria basin (609 

 million barrels to the end of 1973) and the onshore stratigraphic and 

 structural trends are anticipated to continue seaward. For similar 

 reasons, the Eel River basin is believed to be an excellent prospect. 



The Washington-Oregon OCS is a region that is part of a trough _ 

 extending from the Cascade Mountains near the coastline to the continental 

 slope on the west. Although oil and gas seeps and petroliferous muds 

 have been found onshore near the coast, there has been little production. 

 However, limited offshore drilling and geophysical surveying suggest that 

 the offshore presence of suitable sediments exists together with 

 stratigraphic-structural traps. 



Alaska is the northern terminus of the mountain system which 

 extends in a continuous belt along North and South America (the American 

 Cordillera). Surrounding Alaska offshore are a number of sedimentary 

 basins that are potential or proved oil and gas provinces. These basins 

 lie in southern Alaska, the Bering Sea, Chukchi Sea and Beaufort Sea.
