Decide plunger lift feasibility
in minutes, not weeks.

A purpose-built petroleum engineering workbench for screening, sizing and optimising plunger lift systems. Enter well data once — get pressure analysis, cycle timing, operating envelope and a suitability grade you can defend.

Everything an analyst needs, nothing they don’t.

Built around the calculations and visualisations petroleum engineers actually use in plunger lift screening reports.

Foss-Gaul Pressure Engine

Industry-standard CPmin calculation decomposed into line pressure, plunger weight, liquid load and gas-expansion components.

Operating Envelope

CPmin vs depth across slug volumes — identify the safe operating zone before committing to a design.

Cycle Timing Gantt

Fall → Buildup → Rise → Afterflow timing with plunger depth trajectory overlaid.

Wellbore Schematic

Scaled visualisation of tubing, casing and plunger position through the cycle.

Executive Dashboard

Suitability grade, KPIs, GLR feasibility, and prioritised recommendations — at a glance.
