Latest Patents

Coates' latest patents include groundbreaking inventions such as the "NMR logging apparatus and methods for fluid typing." This novel method and apparatus focus on the separation of fluid phases in borehole measurements. The technique involves selecting an optimum contrast mechanism and a corresponding set of measurement parameters tailored to specific borehole environments. The contrast mechanism can utilize various factors, including diffusion, relaxation time, or hydrogen index differences among different fluid types. Initial measurements are made, and the parameters are compared to predetermined values to estimate the types of fluids present in the geological environment. If necessary, measurements can be repeated to achieve optimal fluid typing for the estimated fluid types.

Another significant patent is the "NMR apparatus and methods for measuring volumes of hydrocarbon gas and oil." This invention presents a multifrequency method using triple-wait-time to determine gas- and light-oil-filled porosity across a wide range of reservoir conditions. The method enhances the signal-to-noise ratio and improves the determination of T values for hydrocarbons, particularly in reservoirs containing various fluid types. Conditions are derived to select optimum acquisition parameters for logging applications, enabling accurate determination of pore volumes occupied by each hydrocarbon phase and water.
