A small library of browser-based engineering tools and open-source utilities for natural gas well operators. Use them as quick references at the truck or as planning aids before you commit to a workover. None require an account.
Enter tubing ID, flowing tubing pressure, temperature, gas SG, and liquid type. Get critical velocity (ft/s) and critical rate (Mcfd) from all three correlations side-by-side, with a regime-aware recommendation for which one to use as your operational threshold.
The Python companion to the calculator above. Compute Turner / Coleman / Lea critical velocity and critical rate programmatically. Useful when you need to run the calc across a portfolio, embed it in a notebook, or drop it into a SCADA pipeline. Apache-2.0 licensed.
The SCADA signals that fire 5-14 days before MCF rate confirms a well is loaded. With critical-velocity context, a 24-hour decision tree, and the cost of misdiagnosis ($10k–$40k per workover).
Pre-tuning data, target arrival velocity by plunger type, cycle and afterflow tuning rules, fall-time triggers, and a tune-vs-redesign decision matrix. Field-engineer-grade reference.
Liquid loading, paraffin, artificial lift drift, chemical program drift, and gathering/RTU faults — the SCADA signatures of each, the cost exposure, and why daily automated review catches them faster than manual scroll.
WellRX charter partners (20-200 well gas operators) get every well diagnosed against critical velocity, the seven early-warning signs, the 21-point plunger checklist, and 40+ other patterns daily, before 6:30 AM CT. Setup waived, 50% off three months, penalty-free wind-down at week 12.
