3.Calculated well data for use in integrated modeling
Data is stored row by row; the first row is the table header
Each row corresponds to a combination of parameters specified by the VFPCASES keyword
The parameter variation order matches the order specified by the VFPCASES keyword
The fastest-changing index corresponds to the first VFPCASES parameter, that is, FLOWRATE
Missing value -9999
If calculation is not possible for any combination of parameters specified by the VFPCASES keyword, all calculated data is filled with the missing value
List of available calculated data (IpmVlpResultType):
PRESSBOTTOM - bottomhole pressure, atm
TEMPBOTTOM - bottomhole temperature, C
TEMPTUBING - tubing head temperature, C
GASVELOCITY - gas velocity, m/s
LIQVELOCITY - liquid velocity, m/s
MIXVELOCITY - mixture velocity, m/s
FLOWRATE - liquid flow rate, m³/day (or oil, m³/day, or gas, thsd m³/day)
PRESSINTAKE - pump intake pressure, atm
