The boundary integral method for the D.C. geoelectric problem in the 3-layered earth with a prismoid inhomogeneity in the second layer
The paper presents algorithm and numerical results for the boundary integral equations (BIE) method of the forward D.C. geoelectric problem for the three-layered earth which contains the prismoidal body with sloped faces in the second layer. This situation occurs in the sedimentary basins. Although...

| description | The paper presents algorithm and numerical results for the boundary integral
equations (BIE) method of the forward D.C. geoelectric problem for the three-layered
earth which contains the prismoidal body with sloped faces in the second layer. This
situation occurs in the sedimentary basins. Although the numerical calculations are more
complicated in comparison with faces orthogonal to the x, y, z axes, the generalization to
the sloped faces enables treatment of the anomalous fields for the bodies of more general
shapes as rectangular prisms. The graphs with numerical results present isoline maps of
the perturbing potential as well as the resistivity profiles when the source field is due to
the pair of D.C. electrodes at the surface of the earth. Also presented apparent resistivity
curves for the Schlumberger array AMNB sounding. |
