Hydrocarbon pore volume Injected (HCPVI)
Hello Everyone:
I have the volume of water injected in reservoir barrels and I can compute the hydrocarbon pore volune. so How do I compute the hydrocarbon pore volume injected?
Thanks for the help.

Yes, you need to plot IWR, Injection withdrwal ratio. it is relly very important indicator for water flood
You know the water volume, it is no problem
About Hydrocarbon (withdrawl) you should have the Formation volume factor for your both oil and gas measured in lab test (PVT)
Once you get the FVF for oil and gas at the current reservoir pressure, and you have the quanteties of oil and gas at standard conditions (surface pressure and temp.) you can multiply your monthly Cum. oil by Oil FVF and add it to multiply Cum. monthly gas prod. by Gas FVF
If you didnt get it clearly please provide us with these values so we can calculate it together

Aries,
You can calculate the fraction of the HCPV injected by (Iw*Bw/(Reservoir Volumes of OIL and GAS) Add GIIP if there is a gas cap. This gives the % of the PCPVI and then plot PCPVI% vs WC or Recovery Factors to monitor the WF
For reservoir volumes you need to multiply stock tank volumes by either Bo or Bg, whatever is the case.
