Latest Patents

Brian Spies holds a patent for "Methods and apparatus for dynamically estimating the location of an oil-water interface in a petroleum reservoir." This patent outlines methods for locating an oil-water interface by taking resistivity and pressure measurements over time. The apparatus includes sensors arranged as distributed arrays. The first method involves acquiring resistivity and pressure measurements simultaneously during a fall-off test. These measurements are used to estimate the radius of the water flood front around the injector well based on known local characteristics. The flood front radius and fall-off pressure measurements are then utilized to estimate the mobility ratio. The second method involves acquiring resistivity and pressure measurements at various times, where prior knowledge about reservoir parameters is quantified in a probability density function (pdf). By applying Bayes' Theorem, prior pdfs are combined with measurement results to obtain posterior pdfs that quantify the accuracy of additional information. The third method represents uncertainty about reservoir parameters using Gaussian pdfs, with the relationship between measurements and parameters approximated by a linear function.
