Abstract
Since progressive exploration started in Block 1/2/4, Sudan Six new oil fields have been discovered, namely Talih East 1, Talih East 1, Talih South, West Unity 2, Unity 69, Unity 22 and El Full-6. The new Ghazal thick oil-bearing series in Talih and Talih West has been found, with 677 MMSTB of OOIP (178 MMSTB reserves) and more than 80k STB/D production was added to the daily production plateau of GNPOC, Sudan. The main techniques applied include merging existing 3D seismic data to eliminate the marginal effect, optimizing appraisal well locations by comprehensive geological study, reviewing logging data of existing producers, identifying low resistance pay zone to confirm oil bearing structure, determining well location by integrating the results of the nearby producer performance analysis and well pattern optimization.
