Well Nodal Analysis Software
PQplot software is the core petroleum engineering engine of the pengtools.
PQplot software calculates inflow performance relationship IPR and vertical lift performance VLP curves for oil and gas wells.
PQplot software is available online at www.pengtools.com.
Typical applications
- Calculating the Well Nodal Analysis [1] model of the well
- Matching the Well Nodal Analysis model to the well test data
- Calculating and exporting the IPR curves: Vogel's IPR, Composite IPR
- Calculating and exporting the VLP tables to Excel or reservoir simulator
- Estimation of well's Production Potential and absolute open flow (AOF)
- Tubing sizing
- Gas lift design
- Selection of the operating wellhead pressures
- Estimation of the effects of reservoir pressure depletion
- Sensitivity studies
Main features
- Multiphase flow correlations
- Plot of Inflow performance curve IPR and Vertical lift performance curve VLP
- Rate and pressure at intersection point
- Tubing, annular and tubing+annular flow types
- "Default values" button resets input values to the default values
- Switch between Metric and Field units
- Save/load models to the files and to the user’s cloud
- Share models to the public cloud or by using model’s link
- Export pdf report containing input parameters, calculated values and plots of the PQplot
- Continue your work from where you stopped: last saved model will be automatically opened
- Download the chart as an image or data and print (upper-right corner chart’s button)
- Export results table to Excel or other application
Demo
The demo is a copy of a training seminar. This video demonstrates basic functionality of the PVT Software and PQplot software. It is shown how to create the well nodal analysis model, run sensitivity, save the model.
In this demo we are solving the homework where it was asked to:
- Calculate the flowing bottomhole pressure.
- Construct VLP curve
- Construct IPR and calculate AOF
- Calculate current production efficiency (production/AOF)
- What is the production potential and what actions do you propose to close the performance gap?
- What will be production increment from the proposed actions?
