The present disclosure generally provides apparatus and methods for removing a subsea well head. The apparatus may include an embedded shear comprising a pile and a shear cutter integrated into the pile. The shear cutter may be mounted within the pile near a lower end thereof. The pile may include a well head conductor receptacle adapted to receive a subsea well head, and the shear cutter may include a shear blade that extends across the well head conductor receptacle when activated. The method may include providing a pile with a shear cutter integrated therein, lowering the pile over the well head, pumping water out of the pile to drive the pile into the seafloor to a desired cutting depth, activating the shear cutter to cut off a portion of the well head, and pumping water into the pile to drive the pile out of the seafloor.
