SPipe

Short description of sPipe tool

sPipe is a simple surface pipeline sizing tool. It calculates pressure drop in oil, gas or water flowlines. Featuring multiphase flow correlations and sensitivity analysis.

Typical applications include

* Estimation of flowrate with defined pressures at inlet and outlet
* Estimation of inlet and outlet pressures for achieving target flowrate
* Selection of pipeline size 
* Estimation of mixture velocity

Main features

* Plot of pressure profile vs length
* Result table with pressure, velocity and hold-up
* Sensitivity analysis
* Using prepared PVT models
* Account for elevation
