Artificial lift
This paper presents a robust workflow to identify optimization opportunities in gas lift wells through real-time data analysis and a surveillance-by-exception methodology.
To overcome operational constraints tied to ball-and-seat valves, an operator tested a spring-loaded alternative downhole.
Field results highlight how rethinking tubing-anchor-catcher design can reduce gas interference and support late-life production.

The performance of artificial-lift systems on horizontal wells is greatly influenced by both the volume of gas produced and the tendency for gas slugging. -
Of the many steps in the journey toward maximizing run life, the first steps should be to identify the system requirements and communicate those to the vendor. This can be challenging, because operators and suppliers often speak different languages. Fortunately, international standards can help.

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.
