Abstract: A hanger apparatus inserted into the earth and from which the drill casing of a well is hung comprising a central sleeve having a plurality of structural arms extending outwardly therefrom, each terminating in a pile sleeve. A plurality of pipe joints, welded end to end are hammered into the earth through each of the pile sleeves thus "nailing" the central sleeve in fixed position in the earth mass surrounding it. As the pile is driven downwardly through each pile sleeve means it is driven progressively radially outwardly from the central sleeve means so that the piles define a pyramidal mass of earth therewithin that locks the central sleeve still further within the earthen mass. The casing ultimately is affixed such as by welding, to the central sleeve.

Abstract: A method and apparatus for controlling the depth at which deviation occurs of a conductor casing driven vertically into the ocean floor from an offshore oil platform. A retractable shear pin engages both members of an articulated joint inserted between two sections of the conductor casing, thus preventing relative movement and locking it into a uniform vertical alignment. This ambient pressure increases with depth, thereby tending to force the shear pin to retract. Movement of the shear pin is internally prevented until the force exerted by the pressure exceeds a desired precalculated valve. The shear pin disengages from the articulated joint, resulting in deviation of the path of the conductor casing at a remote point.

Abstract: A method and apparatus for deviating a conductor casing, or the like, after it has been driven into a substratum, generally beneath the floor of a body of water. The conductor casing is characterized by a drive shoe assembly on the end thereof having a bevel cut extending therethrough for up to 180 degrees of the circumference thereof, or more, and thereby providing a residual connection characterized as a hinge means. The conductor casing and drive shoe is characterized in operation by an entire linear configuration until they are driven beneath the floor into the substratum, at which time the hinge means allows closure of the distal end through the arc of the bevel cut thereby providing a deviated section which produces directional implacement of the conductor casing.
