A Review of Geological Characteristics and Improved Oil Recovery for a High Temperature Fractured Basement Reservoir, Vietnam

The White Tiger field is currently the biggest fractured basement reservoir on the continental shelf of Vietnam. This reservoir has a complicated geological structure with high temperature and closure stress. Thus, experiences that have been learned from this field operation are good lessons. This article reviews significant events in geological development, achievements in the early development, and late stage to improve oil recovery by special methods for fractured granite basement reservoirs, such as hydraulic fracturing, water flooding, water shut-off, surfactant flooding, and changing pressure regime. It is a worthy case study for both current and future development planning of basement reservoirs in the world.
