Electromagnetic effects of steel-cased wells
In oil and gas production environments, controlled-source electromagnetics can be used to aid brownfield exploration, development, and reservoir monitoring efforts. However, such environments typically have many highly conductive steel-cased wells in the area of interest. In this paper, we present a modeling algorithm using a method of moments approach to calculate the electromagnetic response of multiple 3D steel-cased wells of arbitrary geometry in a layered earth conductivity model. First, we divide each casing into a collection of segments, each carrying a uniform current density. Next we ...
