Miscible Gas Injection Issues in a Thick Carbonate Volatile Oil Reservoir

D09 MISCIBLE GAS INJECTION ISSUES IN A THICK CARBONATE VOLATILE OIL RESERVOIR Abstract 1 This paper discusses a number of challenges around the development by miscible gas reinjection of the Kashagan field situated in the North Caspian. The Kashagan field is a highly pressured sour carbonate oil reservoir. Due to the lack of a significant local gas market and the cost associated with treating the sour products re-injection of the associated gas is intended from early in the field development. This is not only environmentally and economically very sound but will also significantly enhance the recovery efficiency due to the
