摘要
A system and computer-implemented method for characterizing hydrocarbon gas net pay zones in a subterranean reservoir including determining a sweet zone indicator from well log data, determining rock properties from well log data, and identifying one or more classes of net pay zones from the sweet zone indicator and rock properties. The sweet zone indicator may be determined by computing neutron-density separation and using the neutron-density separation and the well log data. The rock properties determined from the well log data may include total water saturation, adsorbed gas saturation, total gas content, porosity, propensity for hydraulic fracturing, uncertainty level of the total water saturation, uncertainty level of the total gas content, and baselines for the porosity and total gas content. Using the sweet zone indicator and rock properties, one or more classes of net pay zones can be identified.
