Abstract:
A method of balancing a beam pumping unit can include securing counterweights to crank arms, thereby counterbalancing a torque applied at a crankshaft at a maximum torque factor position due to a polished rod load and any structural unbalance. A well system can include a beam pumping unit including a gear reducer having a crankshaft, crank arms connected to the crankshaft, a beam connected at one end to the crank arm and at an opposite end to a rod string polished rod, and counterweights secured to the crank arms, and in which a torque applied at the crankshaft at a maximum torque factor position due to weights of the crank arms, the counterweights and wrist pins equals a torque applied at the crankshaft at the maximum torque factor position due to a load applied to the beam via the polished rod and any structural unbalance.

Claim (Index 5):
The method of  claim 1 , in which the securing comprises positioning the counterweights at respective positions along the crank arms, so that a torque applied at the crankshaft at the maximum torque factor position of the crank arms due to weights of the crank arms, the counterweights and one or more wrist pins equals the torque applied at the crankshaft at the maximum torque factor position of the crank arms due to the polished rod load and any structural unbalance of the beam pumping unit.
