Enhanced Gas Recovery: Benefits Seen in Downhole vs. Wellhead Gas Compression
Extensive analysis has led to the conclusion that downhole gas compression provides a greater increase in gas production than wellhead gas compression because of the additional drawdown created.

This paper presents an artificial-lift selection process to maximize the value of unconventional oil and gas assets.
Well-Performance Calculations for Artificial-Lift Screening
This paper focuses on a fit-for-purpose methodology to evaluate well-production performance for a wide range of artificial-lift techniques.
Two things stood out when I looked at this year’s abstracts. First, well over half of the abstracts were related to electrical submersible pumps (ESPs). This is a significant increase from the last couple of years. Second, there was a clutch of artificial-lift-method-selection papers.
With Over 200 Shale Well Installs, This Slug-Smoothing Lift Technology Is Boosted By Schlumberger JV
Slug flow has made the life of an unconventional production engineer a bit complicated, but a new downhole technology may smooth things right out by solving some big artificial lift problems for the shale sector.
Gas Lift Use Grows in Permian
Unconventional production patterns in the Permian Basin are leading producers to replace electrical submersible pumps (ESPs) with gas lift, which had been little used there.
Four Honored as Legends of Artificial Lift
The 2016 SPE Legends of Artificial Lift are announced. Recipients will be honored at the 2016 SPE Artificial Lift Conference and Exhibition for North America to be held this month.
Operators Begin Considering Pumps on Older Subsea Fields
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.
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.
Evaluation of Intermittent-Flow Behavior Upstream of Electrical Submersible Pumps
This work experimentally investigates the behavior of an intermittent multiphase liquid/gas flow that takes place upstream of an electrical submersible pump (ESP).
Run-Life Improvement by Implementation of Artificial-Lift-Systems Failure Classification
This paper describes a methodology for classification of artificial-lift-system (ALS) failures and addition of a commonly used root-cause failure classification.
Methodology Evaluates Artificial-Lift Requirements Amid High Uncertainty
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.
In-Well Dual Canned ESP Completion Test To Validate Safe Deployment in Deep Water
Deepwater and ultradeepwater completions use numerous hydraulic control lines for control and actuation of downhole equipment.
New Technology To Cut Electric Costs, Not Production
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.
Encapsulated ESP Handles Multiphase Flows To Extend Run Life and Boost Oil Recovery
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.
Balancing Artificial Lift, Chemical Injection To Achieve Production Goals Over Life of Well
Production engineers are often asked to manage both the artificial lift (AL) system and the upstream chemical injection program for a project.
Artificial Lift Experts Warn of Long-Term Production Issues in Horizontal Wells
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.

Paying Close Attention to a Gas Lift System Can Be Rewarding
When a gas lift system starts performing poorly, there is a good chance no one will notice. It is not an event that demands attention like a broken pump. A gas lift system will continue injecting gas into wells and oil will continue to come out. Just not as much oil as there could be.
