Artificial lift
In the wake of the falling number of exploratory wells in the country, Brazil-owned Petrobras addressed audience concerns as well as outlined new avenues for production at the Offshore Technology Conference.
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-pump (ESP) technology is a proven artificial-lift method for shallow, low-pressure reservoirs such as those found in the West Sak viscous oil field in Alaska. -
Fast-declining, older, unconventional oil wells require artificial lift experts to deal with and explore a population of miles-long horizontal wells that do not follow the established rules of thumb.

The 2018 Legends of Artificial Lift are announced. Recipients will be honored at the 2018 SPE Artificial Lift Conference and Exhibition to be held in The Woodlands, Texas.
-
Hundreds of rod-lift wells in North Dakota are about to get a big upgrade.
-
Venture groups spend their time evaluating hundreds of companies each year to only make a handful of investments. These two cover interesting ends of the upstream spectrum: aerial drones and downhole artificial lift.
-
This paper presents how a US onshore operator took a three-step approach to optimize more than 100 rod-pump wells. The approach involved data consolidation, automated work flows, and interactive data visualization.
-
This paper presents a comparison of conventional ESP methods and artificial-sump systems for which free gas and gas slugs are a challenge.
-
This paper describes the consequences of using an assumed R ratio in a gas-lift design that is not the same as the actual R ratio of the valve.
-
One of the more exciting aspects of artificial lift is the constant influx of new technologies and new ideas that the discipline invites. Inventors appear to be regularly developing “the next new thing” in artificial lift.

Subsea pumps are used for gas/liquid separation, subsea compression, and subsea boosting. Solutions aiming at cost reductions are crucial to make subsea processing projects feasible. A cost- and complexity-reduction solution for the subsea electrical power supply is a critical consideration.
