Modelling the radio imaging method using electric dipoles in a homogeneous whole space
Bibliographic record
Abstract
Summary Information as to how the signal of the Radio Imaging Method (RIM) changes when the system parameters change or the rock properties change is not well documented. Having a better understanding of the impact of these changes would assist in interpretations of RIM data. To quantify the impacts, a simulation of a RIM system was created in Matlab®. Representing the transmitter as a harmonic electric dipole, the simulation was set up to allow calculations of the amplitude and phase of the radiation at any point in a homogeneous whole space. This basic model allows an investigation of how the response changes due to three different types of variables: 1) the physical properties of the rock that the radiation passes through (conductivity, dielectric permittivity, and magnetic permeability); 2) the geometric parameters of the system (the distance between, and the angle between the two boreholes; and 3) the characteristics of the transmitter (frequency, current, and size). An investigation of the RIM signal in the context of varying these parameters will assist in understanding the results and the interpretation of complex geometric situations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
