Abstract
A method for determining at least one of a mud density or a standoff, includes determining, a short-spaced density, a long-spaced density, and a time of sound propagation between a tool body and a borehole wall. The method also includes determining, based at least in part on the short-spaced density and the long-spaced density, a formation density using a spine-and-rib-diagram. The method further includes determining a distance-to-spine value based on the short-spaced density, the long-spaced density, and the formation density. The method includes determining a mud density approximation, based at least on the distance-to-spine value. The method also includes determining a standoff approximation, based at least on the mud density approximation. The method further includes determining, based at least on the mud density approximation and the standoff approximation, at least one of a computed mud density or a computed standoff.
