Pipe:

One phase Moody’s correlation with Haaland’s correlation are

used for calculation of the turbulent friction coefficient;

Beggs&Brill’ s multiphase correlation.

Choke:

Mechanistic correlation for subcritical/critical flow regimes;

Ashford&Pierce’s correlation for subcritical/critical flow regimes.

Pump/Compressor, the calculation can be based on:

pressure ratio;

pressure difference;

pressure after equipment;

equipment power.

Development plans: VFP Designer

Well design modeling: casing column, tubing string, perforations, packer

Creating vertical flow performance (VFP) tables for wells and surface network

Matching based on experimental points

Updating VFP tables at time steps based on the current fluid composition

Taking into account well design: different VFP tables for different well’s segments
