  • Method of monitoring behavior of carbon dioxide in porous aquifer by using marine controlled-sources electromagnetic survey
    Patent number: 8384389
    Abstract: A method of monitoring a behavior of carbon dioxide in a stratum by using a marine Controlled-Sources Electromagnetic survey, includes: (S10) collecting a sample of sandstone at a stratum for charging carbon dioxide; (S20) calculating an effective porosity of the collected sample; (S30) measuring an electrical resistivity by saturating the collected rock sample with a pore fluid having a different concentration; (S40) forecasting a change of an electrical resistivity of stratum by charging carbon dioxide; (S50) carrying out a Marine CSEM exploration before and after charging the carbon dioxide separately in each step; and (S60) monitoring a charging behavior of carbon dioxide in stratum by a Marine CSEM exploration.

  • Method for evaluation of the ground reinforcement effect using 4-D electrical resistivity monitoring
    Patent number: 8217668
    Abstract: Disclosed is a method of evaluating a ground reinforcement effect using 4-D electrical resistivity monitoring, wherein the ground reinforcement is made up on an underground cavity through cement mortar grouting, the method including: (a) installing a survey line for measuring electrical resistivity in a ground reinforcement zone; (b) measuring the electrical resistivity of the ground reinforcement zone through the survey line before grouting mortar, and imaging three-dimensional electrical resistivity distribution in the ground reinforcement zone by applying a three-dimensional electrical resistivity inversion to the measured results; (c) measuring the electrical resistivity of the ground reinforcement zone through the survey line while or after grouting the mortar, and imaging the three-dimensional electrical resistivity distribution in the ground reinforcement zone by applying the three-dimensional electrical resistivity inversion to the measured results; and (d) calculating a change ratio of the electrical
