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 8):
The unit of  claim 1 , further comprising:\n a prime mover disposed adjacent the frame; a crank arm connected to the prime mover and rotatable thereby about a crank point, the crank point disposed at a first (K) dimension relative to the fulcrum point; and a pitman arm having a second (P) dimension and connected between a first bearing point on the crank arm and a second bearing point on the second end of the beam, the first bearing point disposed at a third (R) dimension from the crank point, the second bearing point disposed at a fourth (C) dimension relative to the fulcrum point, whereby the crank arm rotated by the prime mover about the crank point translates the pitman arm to oscillate the beam on the fulcrum point and reciprocates the rod load along the wellbore axis.
