Abstract

A method for determining a dip of a geological structure in a subterranean formation, involves generating, using a 3D resistivity analyzer, a first intermediate result describing the dip of the geological structure based on 3D resistivity data collected from a borehole penetrating the subterranean formation. The method further involves generating, using a borehole image analyzer, a second intermediate result describing the dip of the geological structure based on a borehole image collected from the borehole. The method further involves generating, by a computer processor combining the first intermediate result and the second intermediate result based on a pre-determined criterion, an integrated result describing the dip of the geological structure.
