Artificial Lift

Two things stood out when I looked at this year’s abstracts. First, well over half of the abstracts were related to electrical submersible pumps (ESPs). This is a significant increase from the last couple of years. Second, there was a clutch of artificial-lift-method-selection papers. I have not seen many of those recently. Because this appears to be a topic of interest at the moment, I chose papers from that topic. They are good papers, and it is a good general-interest topic, but selecting them meant that I had to leave out more-specialized papers.

I am primarily an ESP guy, so I have to be cautious about bias when looking at papers. Biased or not, I thought several of the ESP-related papers stood out. SPE 185128 discusses ways to operate an ESP below 800 psi. This has been a problem in multifractured horizontal wells. SPE 184216 discusses the effect of horizontal-well multiphase-flow behavior on ESP operations. Long gas/liquid slugs are another problem I have been seeing. SPE 172736 discusses casing corrosion induced by stray currents from weakened ESP-power-cable insulation. This is a topic of interest in the Middle East but is largely ignored in the US.

I also admit to having a biased interest in multifractured horizontal shale wells. I thought SPE 180833 might be of interest because it discusses optimization of oil-well plunger lift. I have been wondering if plunger lift might be a viable late-life lift method for these wells. Last, SPE 180470 seemed like a solid gas lift optimization paper. As much as it pains me to admit it, by the book, gas lift should be the default lift method for shale wells.
