Artificial lift
The paper presents successful field tests designed to decrease electrical-submersible-pump cooling rates by inducing controlled deadheads rather than shutting down the pumps.
The authors of this paper develop a model that can predict well-risk level and provide a method to convert associated failure risk of each element in the well envelope into a tangible value.
The paper presents results of single-phase and multiphase electrical-submersible-pump tests as well as operation data, lessons learned, and failure examples gathered over 10 years of operation in a highly viscous offshore oilfield.

Do you know how many of your organization’s wells are artificially lifted? Or, more importantly, do you know what fraction of your production volumes are dependent on artificial lift? I would wager that the percentages are higher than you would expect, and I encourage you to seek out that information and share it.
