WebOnshore applications of direct current resistivity (DCR) along shorelines suffer a short-circuit-like phenomenon due to electrical current flowing through a more conductive body of water rather than ground. Our study of the numerical simulation of DCR data with a three-dimensional forward model demonstrated that the apparent resistivity was reduced as a … WebAug 1, 2024 · The project's primary objective is to evaluate the reducing capacity of an aquifer down-gradient of a roll-front ore zone to assess the mobility of uranium and other associated elements (e.g. arsenic, selenium, molybdenum, and sulfur). Assessing the reducing capacity of the aquifer requires characterization of the mineralogy, …

WebResistivity modeling for arbitrarily shaped three-dimensional structures. A. Dey, H. Morrison. Published 1 April 1979. Geology. Geophysics. A numerical technique has been developed to solve the three‐dimensional (3-D) potential distribution about a point source of current located in or on the surface of a half‐space containing an arbitrary ... WebCyclic loading affects the electrical conductivity and fluid permeability of kaolinite clay-bearing sandstone. The effective confining pressure on two sandstones was repeatedly raised and lowered between 3.5 and 31.5 MPa.
