This paper presents techniques for detecting and evaluating fractured reservoirs from porosity (sonic, neutron, or density) and resistivity logs. It is shown that the porosity exponent of a naturally fractured reservoir should be small compared with the porosity exponent of the matrix. A series of charts was generated for estimating the porosity exponent as a function of total porosity, matrix porosity, and the porosity exponent of the matrix. Three examples are presented.
