Abstract
A method of reducing uncertainty, which exactly finds the hydraulic conductivity and the specific storativity of a rock sample in pressure pulse-decay measurement. Axial and confining pressures are applied to the rock sample, and upstream and downstream reservoirs are connected to the rock sample. Coordinate values representing minimum values of a contour of a graph of an objective function, in which the hydraulic conductivity and the specific storativity obtained through the pressure pulse-decay measurement scheme to apply pressure pulses from the outside are expressed in horizontal and vertical axes are found from the graph. The coordinate values are set as the hydraulic conductivity and the specific storativity of the rock sample. Graphs of objective functions obtained by repeating the pressure pulse-decay measurement while changing boundary conditions are shown in overlapped, thereby reducing the uncertainty of the hydraulic conductivity and the specific storativity of the rock sample.
