“The Plunger Lift app helps me optimize and manage over 300 wells. All the functionality I need is there and the software tools and support resources are really useful.”

PLC SHIFT
PLUNGER LIFT
Optimize production of your gas well with advanced features such as critical flow and automatic tuning.
PLUNGER LIFT is a complete plunger lift control and optimization application for PLC SHIFT that increases production from liquid rich natural gas wells. As water or hydrocarbon liquids build up in the well the hydro static head pressure impedes gas flow. A plunger is placed in the well and the flow valve is actuated to bring this liquid to the surface and reduce pressure on the formation. This actuation is determined based on numerous factors.
Key Features
Arrival Time Optimization
Automatically adjust Flow and Shut-In condition set points in real-time to maintain a desired plunger arrival time
GAS LIFT App Integration
Seamless integration for Gas Assisted Plunger Lift (GAPL) and Plunger Assisted Gas Lift (PAGL)
Critical Flow Calculation
Determine the minimum flow rate to naturally bring liquid to surface, Turner and Coleman calculations supported
GAS FLOW App Integration
Flow measurement for Flow and Critical Flow conditions
Plunger Recovery Mode
Temporarily increase Off Time to recover a stuck plunger
