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.
