SR-13Foundational
PVT Modeling & EOS Tuning
Extracts fluid study data from decades of laboratory reports and tunes the equation of state against all of it, not against the one report someone had to hand.

Automated Nodal Analysis
In one sentence
Runs the inflow-outflow calculation for every well in the field on a schedule, instead of for a few wells when someone has time.
The problem
Nodal analysis is the standard tool for finding where a well is constrained, and it is typically applied to perhaps five per cent of wells in a year because each model is built by hand.
How it works
Well models are generated automatically from the completion database and calibrated against the latest well test, then run field-wide on a schedule. Results identify whether each well is inflow-constrained, tubing-constrained or surface-constrained, which determines whether the answer is a stimulation, a tubing change or a facilities fix.
Data required
- Completion geometry and tubing detail per well from the master database
- Latest well test with flowing pressures
- PVT properties by reservoir
- Separator and network back-pressure
What you get
- Operating point and constraint type per well, refreshed monthly
- Sensitivity to tubing size, choke and back-pressure change
- Field-wide ranking of wells by unrealised potential
What it cannot do
Automatically generated models are as accurate as the completion database behind them, and completion records in brownfields frequently disagree with what is physically in the well. The system cross-checks the model against the well test and flags wells where the two cannot be reconciled, which is typically ten to twenty per cent of a mature field — and those wells need a records exercise, not a better model.
