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 16):
A reciprocating pump system for a well having a wellbore axis intersecting at an inclination relative to surface, the system comprising:\n a downhole pump disposed in the well; and a pumping unit disposed at the surface and coupled to the downhole pump by a rod string, the unit comprising:\n a frame disposed at the surface and having a fulcrum point; and \n a beam having first and second ends and defining a bend therebetween, the first end connected to the rod load extending from the well at the inclination, the beam pivotable at a pivot on the fulcrum point of the frame, the pivot disposed between the bend and the first end of the beam.
