Latest Patents

Yogeshwar Sharma holds a patent titled "Method for determining horizontal and/or vertical permeability of a subsurface earth formation." This patent focuses on pressure and flow measurements made during the extraction of fluid samples using a borehole logging tool equipped with a single extraction probe. The method analyzes these measurements to derive separate values for both horizontal and vertical formation permeability. By utilizing build-up measurements, the slope of variation of formation pressure is derived concerning a spherical time function. This value is then incorporated into an expression for a dimensionless variable that relates pressure, flow rate, porosity, compressibility, and probe radius. The resulting dimensionless constant provides an index into a look-up table obtained through a new analysis of fluid dynamics in the vicinity of the probe for anisotropic formations. This table yields values for two or more dimensionless variables from which permeability values can be derived.
