Currently over 9, 000 MMCFG/D (255 MMCM/D) is being flared world wide in over 48 countries. In an effort to commercialize a precious resource and in anticipation of future world energy needs, Angola has set aggressive targets to eliminate routine gas flaring in the near future. In 2002 a consortium of Sonangol, Cabinda Gulf Oil Company Ltd, a subsidiary of ChevronTexaco Corporation, Total, and Eni approved the Sanha Condensate Project located offshore Angola in Area B of Block 0.The Sanha Condensate Project will provide up to 35 wells and the facilities to eliminate routine gas flaring in Area B of Block 0 by injecting produced gas into the Pinda reservoir while increasing oil, condensate, and LPG production, which generates an attractive economic return. The cross functional subsurface team is focused on the identification and mitigation of reservoir uncertainties to increase the probability of effectively cycling gas into a complex Cretaceous reservoir. Results from stratigraphic modeling, seismic attribute analysis, fluid analysis, reservoir modeling, and evaluation of existing wells are enabling the team to better understand this complex reservoir, and thus focus drilling efforts in areas of better reservoir quality and connectivity.
