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 de- velopment, such as reserves producing strategy and development mode, was conducted. The de- velopment 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. Keywords Turbidite Channel, Gas Cap, Heavy Oil, Viscosity Distribu
