REMOTE UNITS ELIMINATE UNPRODUCTIVE PUMPING
Henry R. Swartzlander Texaco USA Midland, Tex. Sucker-rod pumpoff controllers (POCS) based on available off-the-shelf remote terminal unit (RTU) components have been developed and installed by Texaco USA in its Midland, Tex., producing area. Market availability of off-the-shelf pumpoff controllers in the early 1980's was limited. However, the fundamental building blocks for a general RTU-based system were readily available.
