Rod pumps with isolated tailpipe systems have been growing in popularity over the past few years and applied in basins all over the US. Some earlier system component designs had vital shortcomings that became more evident over time with the growing install base.
The important fact is that these lessons learned have been a driving force in making positive strides to improve installation procedures, component design, and material selections. Another vital element leading to improved consistencies and better results is an accelerated and expanded knowledge regarding the required nodal analysis to properly predict required production and reservoir properties to yield optimal system function.
This paper will cover the process that has been endured to get to the current improved state of operations and how further success is assumed to be obtained as rod pumps with isolated tailpipes are applied in unconventional wells for years to come.
