Abstract: Electromagnetic (EM) survey processing comprising operating an electronic device to model expected EM field components to be measured by an EM apparatus associated with a subterranean formation, wherein the EM apparatus comprises at least one EM source and at least one EM receiver. The electronic device may be operated to determine one or more ratios of the modeled EM field components. The at least one EM source may be operated to emit an EM signal into the subterranean formation, and the at least one EM receiver may be operated to measure actual EM field components of the EM signal. The electronic device may then be operated to compare the one or more ratios of the modeled EM field components with one or more ratios of the actual EM field components. The one or more ratios of the modeled EM field components may then be updated based on the comparison.

Abstract: A method analyzes a subterranean formation. At least one property of a well casing in the subterranean formation is determined and a plurality of current source vectors at respective positions along a trajectory of the well casing are determined. The effect of the well casing is determined based upon the plurality of current source vectors and the at least one property of the well casing.

Abstract: In one embodiment, a method includes receiving one or more datasets including measured vertical electric and magnetic fields excited by one or more radial and azimuthal electric field antennas from a downtool into one or more processors, wherein each of the one or more datasets corresponds to a different position of the one or more radial azimuthal electric field antennas, simultaneously inverting the one or more datasets using the one or more processors, and as a result of the simultaneous inversion, generating by the one or more processors a three-dimensional (3D) image of a portion of the geological formation.

Abstract: Systems, methods, and apparatuses to generate a crosswell data set are described. In certain aspects, a method includes producing a first electromagnetic field at the earth's surface with a transmitter at a first location, detecting in a first borehole a first field signal induced by the first electromagnetic field, detecting in a second borehole a second field signal induced by the first electromagnetic field, and generating a crosswell data set from the first field signal and the second field signal. A formation model may be created from the crosswell data set.

Abstract: A method may include modeling a bulk electromagnetic (EM) characteristic of a composite material including a fracturing fluid, a proppant, and a sensing additive. The method may further include generating a modeled propped fracture pattern for a subterranean formation having the composite material injected therein, and generating a three dimensional (3D) arrangement of cells based upon the bulk EM characteristic and the modeled propped fracture pattern using an effective medium theory (EMT) model, with each cell having a modeled localized EM characteristic associated therewith. The method may also include injecting the composite material into the subterranean formation to cause an actual propped fracture pattern, collecting EM data based upon the sensing additive within the actual propped fracture pattern, and determining a respective actual EM characteristic for each cell based upon the modeled localized EM characteristics and the collected EM data.

Abstract: An electromagnetic (EM) data acquisition method for a geological formation may include operating EM measurement devices to determine phase and amplitude data from the geological formation. The EM measurement devices may include at least one first EM measurement device within a borehole in the geological formation, and at least one second EM measurement device at a surface of the geological formation. The method may further include processing the phase data independent from the amplitude data to generate a geological constituent map of the geological formation, and identifying different geological constituents in the geological constituent map based upon the measured amplitude data.
