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 sharp downturn in the offshore oil business has sparked interest in using subsea pumps to add production. If those conversations turn into orders, it may convert this rarely used option into a commonly used tool for extending the life of offshore fields.

This work experimentally investigates the behavior of an intermittent multiphase liquid/gas flow that takes place upstream of an electrical submersible pump (ESP).

This paper describes a methodology for classification of artificial-lift-system (ALS) failures and addition of a commonly used root-cause failure classification.
-
When evaluating artificial-lift requirements, sometimes data present uncertainties at the initial planning stage. This paper presents the integrated and structured methodology that was used to deal with high-uncertainty conditions.

Our problem is that we are dealing with multiphase, multicomponent fluids whose compositions change spatially and temporally inside imperfectly understood heterogeneous reservoirs whose characteristics also change spatially and temporally.

Everhart Energy Technology, a startup company based in Beverly Hills, California, has developed a system it believes will help small to medium-sized operators cope with the reality that, while oil prices have fallen, their electric bills have not.

Deepwater and ultradeepwater completions use numerous hydraulic control lines for control and actuation of downhole equipment.

In maturing oil wells, oil production is often restricted as reservoir pressure depletes. Two case studies highlight the application of two-screw multiphase pump systems in to extend well life.

Electrical submersible pump (ESP) systems are critical to achieving the maximum production rates and reservoir pressure drawdown that improve ultimate recovery. But variable volumes of gas in unconventional wells can pose challenges for performance of the ESP.
