1. n. [Formation Evaluation]

A method of analyzing the response of an induction logging tool that considers the contribution of each element of the formation as a perturbation from the average background conductivity. The development of the solution is similar to the Born approximation in quantum mechanics, since the latter also involves a single scattering. The Born response is valid for modest formation contrasts. The zero-conductivity Born response is identical to the geometrical factor.
