Petroleum Generation History of Sirte Basin Source Rocks,Lib

发布时间：2022-02-10 04:01

　　This thesis aims to describes and to evaluate the source rocks in the largest and richest sedimentary basin in Africa and Libya with approximate area around 600,000 km²,in the main basin troughs which includes（Dur Al Abd-Zallah trough,Hagfa trough,Ajdabiya trough,Kotla trough,Dur Attlha trough,Maragh trough and Eastern Sirte Basin troughs）from where the Sirte basin hydrocarbons generated,expelled and migrated.This work basically based on different types of data mainly geochemical data...
