Volume Estimation of the Carbonate Fracture-cavern Reservoir - A Physical Model Study

The carbonate fracture-cavern reservoir is the main target for petroleum exploration and development in the Tarim basin located in western China. The volume of fracture-cavern reservoir is difficult to calculate due to the seismic resolution and these reservoirs’ scale. For this, a simple physical experiment is conducted in which the main step and theory of how to estimate the volume of fracture-cavern reservoirs is presented. Furthermore, a complex physical model is constructed, a wide azimuth seismic data is acquired and processed, and a set of calibration template for reservoir volume estimation is obtained and applied to the field seismic data.
