Abstract:
A method of running a down hole rotary pump using a top drive, sucker rod or any drive shaft from surface. A first step involves providing a gear box having an input end and an output end. The gear box is being capable of receiving an input of a first speed at the input end and producing an output of a second speed which is one of either faster or slower than of the first speed at the output end. A second step involves positioning the gear box down hole with the input end coupled to a remote lower end of a sucker rod and the output end coupled to a rotary activated pump. A third step involves applying a driving force to the sucker rod to rotate the sucker rod at the first speed, with the rotational force being transmitted to the rotary activated pump through the gear box which rotates the rotary activated pump at the second speed.
