Deepwater oil and gas field in West Africa are large, but conventional development methods have poor effects and the economic evaluation results are very marginal, due to the special deposit types and complex fluid characteristics. This paper takes A heavy oil field with gas cap which is turbidte deposition located in Congo deepwater in West Africa for study. Detailed studies on sub division of turbidite channel, reservoir connectivity, oil viscosity distribution and other geological reservoir characterization were carried out. Optimization study of main factors affecting the development, such as reserves producing strategy and development mode, was conducted. The development strategy and methods for improving development effect were presented. The paper also has some guidance and reference value for how to improve the economical values of such marginal oil field development.
