20140069183 | METHOD OF REDUCING UNCERTAINTY IN PRESSURE PULSE-DECAY MEASUREMENT - Disclosed is 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. | 03-13-2014 |
20150027696 | METHOD OF COLLECTING SAMPLE USING MULTI-PACKER AND APPARATUS THEREOF - Disclosed are a method of collecting samples and an apparatus thereof. The method of collecting a sample using a multi-packer includes (A) dropping a sample collecting container into a borehole to collect a sample; (B) confirming whether the dropped sample collecting container arrives at a predetermined depth; (C) allowing a first packer surrounding an outer portion of a top end of the sample collecting container and a second packer surrounding an outer portion of a bottom end of the sample collecting container to adhere closely to a wall of the borehole by expanding the first and second packers when the dropped sample collecting container arrives at the predetermined; (D) collecting the sample at an outside of a casing constituting the borehole; (E) separating the first and second packers from each other when the collecting of the sample is completed; and (F) retrieving the sample collecting container filled with the sample from the borehole. | 01-29-2015 |
