摘要

The total porosity in a shale gas reservoir is the key parameter to evaluate its potential production capability. Petroleum geologists have been pursuing an accurate way of predicting total porosity in shale gas reservoirs from logging curves. In the Fuling area near Chongqing in China, we use core test data and well logging data, in order to establish a logging response model for porosity. Through the analysis of the data, we found that the porosity and the P-sonic (P-velocity) have a strong correlation. By combining our results with previous research (i.e., physical rock data), we establish a new model which better predicts the total porosity of a given a shale reservoir than the models established in previous research.
