I have no idea why this thing stopped pumping oil during my recording - there were no people around, no security systems, nothing to stop it as far as I could tell! • However, Perdyfly1 wrote to say, The pumpjack stopped because it was on a timer. I repair the wellheads and often have to wait for the timer to restart the pumpjack so I can shut it down myself. Thanks for the info Perdyfly1!!!! • Anyway, a pumpjack can also be called a nodding donkey, pumping unit, horsehead pump, beam pump, sucker rod pump (SRP), grasshopper pump, thirsty bird, and jack pump. These types of pumps are used to mechanically lift liquid out of a well if there's not enough bottom pressure to naturally force the fluid up. • I found this particular unit near the town of Rangely, Colorado, about 440 kilometres (270 miles) west of Denver. • Ken Bailey provided this information on September 12, 2014: • This pump is on a well not far from the Blue Mountain Cutoff, about 2/3 of the way eastward through the ten-mile-wide Rangely Field. The pump model is a Lufkin conventional we used to call '64's, the approximate length in inches that the pump would pull the polished rod out of the well on each upstroke. In the 1950's, Rangely had 500 pumping wells; today only about 90 still have surface pumpers remaining (many are pumped from underground). This Lufkin is an older model, the curved lines on the Equalizer (the part of the rear of the walking beam where the arms from the crank come up to meet it) give it away. At one time, these stretched out in straight rows for as far as the eye could see, set apart from each other on neat 40' spacing like a checkerboard. It was a neat place to grow up, and I wandered the field freely as a kid, but I wouldn't recommend it today... • In August 2013 GilbertLA63 provided this info: • These Lufkin pumping units were ubiquitous in the Long Beach and Signal Hill areas of southern Los Angeles County in the 1950's. None of the pumping units then were on timers, and there were literally wells everywhere you looked. Of course, that included the whole Los Angeles basin. [ed note: as a small boy in Long Beach, during the sixties, I, myself, remember so wells still visible in Long Beach while my family lived there] • In October 2011 hefley4 provided this additional info: • Rangely is located in the great Uintah Desert in the extreme northwest corner of Colorado -- the desert stretches deep across the border into Utah, and much of Dinosaur National Monument is found on or near it. It is reputed to be the bed for an ancient inland sea, not surprising as many large oil deposits are found beneath former oceans that provided the immese pressure to crush the fossil remains into oil over long periods of time. • hefley4 added this information in October 2011 as well:: • Artesia's named was changed to Dinosaur somewhere around 1960 to capitalize on the growing tourist trade coming to view the amazing bone discoveries and spectacular scenery of Dinosaur National Monument. In my days in Rangely in the '60's, Dinosaur had no high school, and their kids were bussed the 20 mi into Rangely -- Dinosaur was the Rangely suburbs ... ! • In January 2011 hefley4 added this info: • This pump is a conventional walking beam horsehead type manufactured by Lufkin Industries, probably in the 1950's. Once found in Rangely by the hundreds, Lufkin conventional pumps shared the field with Bethlehem, National, Continental EMSCO, and Oil Well Supply model pumps on original placements, many under silver derrick towers. Most were black back than, before environmental rules mandated the sand paint. All ran continuously back then, but have auto-on-off load-sensors now. There was a picture on the Colo. School of Mines website of this same wellsite with a wooden derrick over a 'National Oil Supply' 1940's oil pump... • In December, 2010 lucincutoff provided this info: • Some wells have timers, others are controlled remotely etc.. I know exactly where this well is. It is about 2 miles west of the town of Rangely. This particular pump is one of the older styles found in the Rangely Weber Sand Unit and is more than 60 years old. • Here's my personal web page about fossil fuels and Peak Oil: • http://www.rogerwendell.com/fossilfue... • 08-23-2010
