Abstract
A method for the determination of anisotropic material properties in subterranean rock formations by means of radially oriented and generally equally angularly spaced sidewall cores obtained by use of a rotary sidewall coring tool. The measurement values obtained from testing of the sidewall cores are utilized to obtain an accurate prediction of the shape of the ellipse that describes the variation in the material property under consideration as a function of direction in the bedding plane of the subterranean rock formation.
