Artificial lift
While equipment run life and reliability remain core concerns, experts say operators are increasingly turning to real-time surveillance and autonomous optimization to unlock new production gains.
This article from the SPE Artificial Lift Technical Section highlights a positive reality of our industry, one that centers on connecting and collaborating for success.
This case study describes how edge computing and industrial internet of things platforms were deployed to automate and optimize production operations across four distinct basins.

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. -
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.

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

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.
-
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.

A panel of experts says US shale producers need to rethink their drilling and completion designs as problems mount for horizontal wells when they go on pump. Hanging in the balance is whether long-term production from many shale wells will be achievable.

Production engineers are often asked to manage both the artificial lift (AL) system and the upstream chemical injection program for a project.
