Abstract:
A surface unit reciprocates a rod string for a downhole pump in a slanted well. The unit has a beam with a bend and pivots at a pivot between the bend and the horsehead of the beam. A post of the unit supports the pivot and is oriented to support the beam's load along the post and reduce bending stress. A crank arm is rotated by a prime mover about a crank point and translates pitman arms to oscillate the beam on the pivot, which reciprocates the rod string at surface along the slanted axis. The unit can be set at various offset distances relative to the intersection of the well so the unit can be used at various inclinations of slanted axis. The horsehead defines a segment with a face to accommodate at least 70% engagement or greater with the rod load for both largest and smallest inclinations.

Claim (Index 7):
The unit of  claim 1 , wherein the first end of the beam comprises a first straight section having a first length, wherein the second end of the beam comprises a second straight section having a second length, and wherein the bend defines an angle between the first and second straight sections and inclining the first straight section downward toward the frame.
