Flow correlation matching
To determine the most suitable flow correlation
Select the required flow correlations
Enter known pressure and temperature at
different measured depths (MD) Enter known boundary conditions
Results show each correlation and the entered
data

Pressure/temperature profile
Compute the pressure and temperature profile for
a system and also vary some other parameters
within system
Enter sensitivity variable Enter boundary conditions
Resulting PSPLOT shows pressure or
temperature against depth (well) or elevation
(flowline)

System analysis
Set up model to compute
Outlet Pressure with given Flowrate
Inlet Pressure with given Flowrate
Deliverability with given any other system variable
In addition, also sensitivity test on
One variable
Several variables that change together
Several variables permuted against one another
Combination of above

Nodal analysis
Classical nodal analysis at any point
Break the system into two and compute the inflow
and outflow around that point
Resulting PSPLOT shows the classicalinflow/outflow curves

Reservoir tables
Produce a table of bottom-hole pressure that
can be utilised by reservoir simulator
Interface to common reservoir simulators such
as:
ECLIPSE VIP

Artificial lift performance
Allows artificial lift performance curves (gas or
ESP) to be generated and also varies some other
parameters within system
To produce input performance curves for GOAL
Resulting plot is gas lift quantity (or ESP power)
versus oil production rate

Horizontal well performance
A horizontal well with multiple sources along the
wellbore which encounters reservoir drawdown
and wellbore pressure drop
Accurately predicts hydraulic wellbore
performance in the completion
Productivity investigation via Optimum horizontal
completion length option

Optimum Horizontal Well Length
Specify:
- reservoir pressure
- outlet pressure
- completion length
