Abstract
A method for predicting hydrocarbon-bearing zones and estimating rock properties by analyzing fluids trapped in the pore spaces or adsorbed on the surfaces of rock samples. The trapped gases are removed under vacuum and analyzed by a mass spectrometer. Data peaks corresponding to petroleum constituent molecules provide an indication of presence and abundance of hydrocarbons. A decrease of the count rate over time is used to estimate permeability and other rock properties. Concentration ratios for selected constituents indicate oil quality and depth of the oil-water contact.
