Technology Focus: Artificial Lift (October 2022)

Abstract

The oil and gas industry tends to have a poor reputation externally when it comes to innovation. Artificial lift is particularly notable in this regard, because the primary lifting techniques used today have existed in some form or format for more than a century. Artificial lift’s status as the “nursing home for wells” probably doesn’t help either. The medical and electronics industries often are praised for innovation, but some antiquated practices and dichotomies remain even in those fields. For example, although great advancements have been made recently in the medical realm in combating a certain virus, just last year I was required to fax something to my medical provider. (When was the last time you were asked to fax something?) And, although the electronics industry has consistently developed smaller, more-powerful computers with incredible storage capacities, the software residing on them has expanded to tax those processors and fill that space. How many megabytes do today’s operating systems require compared with the first version you ever used? It’s been widely reported that the electronics industry is reaching a turning point. Transistors can’t get much smaller because of heat-dissipation limitations, quantum interference effects, and other physics boundaries. Recent articles have lamented the end of Moore’s Law. New paths of thinking, designing, and engineering must be taken to sustain the march of computational progress. Serious attempts are now being made to advance new semiconductor materials, quantum computing, novel system architectures, optimized software, spintronics, and optical computing. Exciting, right? That brings us back to artificial lift, which has long been thriving in the exciting innovation zone that the electronics industry is only now approaching. Just when you think the artificial lift community knows everything, people find new ways to turn old maxims on their head. The selections this month, both the primary selections and recommended-reading selections, are true paradigm-changers. Some examples of hypotheses they challenge include the following: - SPE 204521 vs. “ESPs should never be deadheaded.” - SPE 205134 vs. “Gas-lifted well integrity is not possible to predict.” - SPE 209253 vs. “Rod pumps can’t be modeled using only pressure.” - And one of my favorites, SPE 207596 vs. “Brownfields can’t justify real-time surveillance.” I hope these selections pique your curiosity—or are you still trying to remember the last functional fax machine you encountered?
