ABSTRACT:
A new and improved sinker bar has a substantial portion of its body square in cross section which increases rigidity and decreases wall to wall contact downhole in the production of fluids utilizing a sucker rod string. In addition, when the bars are used with a certain percentage of sucker rods, a greater efficiency and thus reduction of friction is accomplished in production of the fluids downhole.
