... such as kaolinite or illite. In carbonates, high capillarity may be attributed to microporosity caused by recrstallization, dolomitization or oolites that creates seconday porosity.1,2 Most formations logged for potential oil or gas production consist of rocks which without fluids would not conduct an electrical...

Ruppel and Bebout (1996) divided the Grayburg into four high-frequency sequences (HFS) that range from 50 to 100 ft in thickness. The South Cowden reservoir is primarily located in HFS 4, which is divided into eight chronostratigraphic high...

These models use the porosity values displayed by the density and neutron logs, assuming that both tools investigate the same gas saturation profile. They also assume that the variation of gas density and mud...
