Abstract
A device and method for determining strength properties of a subterranean formation. The device is insertable into a borehole formed in the formation, and includes a pair of inflatable semi-cylindrical members mounted on a shaft. The inflatable members when pressurized exert radial force in all directions except along the plane between the members, with the result that a higher parting force is exerted on the formation perpendicular to the plane between the members than across any other plane through the axis of the device.
