  • Method of estimating rock mechanical properties
    Patent number: 9411071
    Abstract: A method of estimating at least one mechanical property value of a rock formation in the geologic past. In one embodiment, a correlation model is generated which correlates at least one mechanical property with a porosity value and a composition value relative to a first rock type. An estimation of a past porosity value and a past composition value is then generated for the rock formation at a point of time in the past. A mechanical property value at the point of time in the past is identified in the correlation model based on the estimated past porosity and past composition values.

  • Method for measuring absorbed and interstitial fluids
    Patent number: 6661000
    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.
