Application of Integrating Seismic Attribute with Simulation in Volcanic Rock Reservoir

The conventional reservoir simulation is only reasonably consistent with history matching. An application will be presented in this paper by integrating seismic data and production data to achieve history matching. It is hard to accurately describe the reservoir and fracture modeling due to lack of fracture logging data in volcanic rock reservoir area of Bin 3. The study found that it has a close relationship between the distribution characteristics of volcanic rock and seismic attributes. The high-value region of coherence cube attribute usually correspond to tight basalts, so it is very like a fracture broken zone. With denser lithology and higher impedance value, the high-angle fractures will be better abundant. Great deals of intensive fracture and comprehensive effect have been simulated through volcanic rock reservoir simulation restricted by seismic data. By improving history matching, the approach also deepens the possible distribution pattern of fracture-developed zone in 3D space. On the basis of that, stable and high production wells have been designed and put forward.
