Abstract

The Pre-Tertiary fractured basement is an important hydrocarbon-bearing reservoir in Vietnam. Due to their very small matrix porosity, basement rocks become reservoirs only when they are strongly fractured, consequently it is a big challenge to construct the porosity model for the basement. Based on the good seismic imaging of the Hai Su Den basement, different seismic attributes have proved to be effective tools in basement fracture characterisation, and the integration of 3D seismic attributes, well data and other geological information by using Artificial Neural Network (ANN) and Co-Kriging techniques has been demonstrated as a good way to construct porosity model for the Hai Su Den fractured basement reservoir. The accuracy of the model has been verified by well results.
