Petroleum Geochemical Characteristics and Accumulation in Offshore of Senegal Basin
摘要
Abstract
Senegal Basin is the largest passive margin basin with salt in western Africa, but it has limited petroleum exploration activities. Only non-commercial petroleum and heavy oil have been discovered before 2010. However, some oil exploration breakthroughs have been made in offshore area in recent five years. The paper analyzed the oils and source biomarkers as well as source rocks rock hydrocarbon potential. The results show that Aptian-Albian and Cenomanian-Turonian source rocks exist in offshore area. The former is characterized by light δ13Corgand lower Sulfur content. The maturity is at oil window or more. The latter is typical of heavy δ13 Corg and medium sulfur content. The maturity is at oil window or low. Oil-source correlation indicates that F-1 Albian oil was generated from Aptian-Albi-an source rocks and F-1 Turonian oil from Cenomanian-Turonian source rocks. While the S-1 Albian oil shows mix sources characteristics.关键词
