Abstract
Methods of detecting and measuring in-situ elastic anisotropy in a subterranean rock formation penetrated by a well bore are provided. The methods basically include exerting pressure on the formation by way of the well bore, and measuring the incremental diametral displacements of the well bore at a location therein adjacent the formation as the pressure on the formation is increased. The magnitudes of the diametral displacements are compared to detect and measure elastic anisotropy in the formation.
