    摘要: A drive shoe (10) for penetrating soil is a larger size than a conductor pipe (11) and connected to the bottom section of the conductor pipe. An exterior band (40) is mounted on the outer diameter and proximate the lower end of the drive shoe. Teeth (28) are spaced at a predetermined interval and extending form and forming the bottom of the drive shoe to enhance penetration into earth formations. The teeth (28) are formed by cutting a beveled section such that the bevel is angled from the drive shoe outer surface towards the drive shoe inner surface. The drive shoe may also have an inner band (41) mounted on the inner surface to further compress the soil away form the interior surface of the drive shoe.

    摘要: An elevator apparatus (10) for manipulating well bore tubing (12) includes a circular body (16) having a top (18) and a central cavity (26) around a body axis (28). The cavity (26) has a diameter allowing the collar portion (14) of the tubing (12) to pass longitudinally therethrough. A plurality of cavity restricting members (36) above the body (16), supported on and spaced apart around the top (18) of the body (16), have proximal (38) and distal portions (40) in respect to the cavity (26). One or more actuators (60) are operatively associated with the petal plates (36) for moving the proximal portion (38) of each cavity restricting member (36) into the cavity (26) an extent sufficient, in combination with the other cavity restricting members (36) so moved, to prevent passage of the collar portion (14) of the tubing (12) through the cavity (26), thereby to hold the tubing (12) with the elevator (10).
