Artificial lift
Three case studies consider the gas-related reasons electrical submersible pumps fail in unconventional shale environments.
Whether it’s reviving inactive gas-condensate wells or identifying overlooked reserves in brownfields, operators are making the most of older wells and fields.

Electrical submersible pumps (ESPs) are the backbone of artificial lift operations, enabling the extraction of hydrocarbons from challenging reservoirs. However, their effectiveness is often compromised by the extreme downhole environment, characterized by soaring temperatures, high pressures, and exposure to aggressive fluids.

An experimental study of a shroud-type downhole separator for a pumped horizontal or deviated well is presented in this study. -
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.

SponsoredRod lift failure frequency in horizontal wells drives significant operating expenses. Understanding why these failures occur leads to a solution — production optimization with automated setpoint changes, which can extend the life of this equipment and reduce downtime.

This paper describes an artificial-lift technology, a subsurface compressor system, that simultaneously removes liquids, increases gas production, and improves recoverable reserves in gas wells.

The way gas injection is used to lift oil and water to the surface needs to change because better control and data may mean more production. At a time when engineers are managing so many wells, they need help from machines.

Getting more out of gas lift requires understanding how gas injections interact with the oil, water, and gas flowing up the well—in other words, multiphase flow. Some papers are listed to get you started.
