HYDROCARBON ACCUMULATION MODEL FOR THE EASTERN STEEP SLOPE OF LAKE ALBERT SAG,UGANDA

CHEN Jingtan;HAN Wenming;QIU Chunguang;JIA Shen;CNOOC Research Institute;  
As the youngest petroliferous basin in the world,the sag of Lake Albert has still undergone rifting up to present.This specific geologic condition leads to a special model of oil and gas enrichment.In order to evaluate and predict the exploration potential on west side of the Lake Albert,we applied seismic and drilling data for studies of the structural characteristics of the sag,and the petroleum geological conditions and accumulation pattern of oil and gas on the steep slope zone.Results show that one-step slope is perfect for lateral hydrocarbon migration and accumulation.Two-step slope is fair,but dominated by vertical migration.Migration and preservation are believed the main controlling factors for oil and gas enrichment on a steep slope as such in the Lake Albert.In the western steep slope,first step slope is favorable zone for exploration.
