Abstract: Drill string components having at least two threads extending around a body. The leading end of each thread can have a configuration having increased strength and resistance to jamming and cross-threading. In particular, the leading end of each thread can comprise a planar surface normal to the body. The leading end of each thread can provide an abrupt transition to full thread depth that helps reduce or eliminate cross-threading and can be oriented at an angle relative to the axis of the drill string component. Each thread can further provide at least one of a variable thread width and a variable thread pitch configured to create an axial progressive fit. Each thread can also provide a cylindrical thread root and a thread crest that circumscribes a frusta-cone over at least a portion of the axial length of the threads configured to create a radial progressive fit.

Abstract: An apparatus for setting a liner in a wellbore that includes a setting tool attached to a work string. The setting tool includes a stretching mandrel and a liner top releasably attached to the setting tool. The liner top includes banded elastomer sheaths positioned in multiple locations along its length. The apparatus may also include a roller screw, operatively attached to the setting tool, so that a rotational movement imparted to the work string causes a forward, rotational movement of the stretching mandrel and engages the stretching mandrel with an inner portion of the liner top so that a protuberance is formed on the inner portion of the liner top and a groove is formed on an outer surface of the liner top.

Abstract: A helical screw pile includes a longitudinal shaft having a top end and a bottom end with a plurality of helical plates arranged on the shaft in increasing diameter from the top to the bottom. The largest diameter helical plate is located toward the bottom of the shaft. A second helical plate having a diameter smaller than that of the first plate is located above the first helical plate. A smaller third helical plate is located above the second helical plate so that the smallest is located toward the top of the shaft. The helical plates can be spaced apart along the shaft or coupled together in an end-to-end manner to form a continuous helix.
