need urgent help on history Match
Hello All
I need some guidance on history match in simulation in terms of parameters to change
for example what parameter to change in order to match:
Cumulative production
GOR
Water cut
Oil Rate
Thank you All for help!

Hello petro,,,
There are a lot of parameters to match that numbers:
- You have to check the PVT data set.
- Check the reservoir volume OIP from volumetrics, OIP from initialization run, OIP from MBE.... etc.
- Validate the reservoir pressure points.
and then for Oil Rate (and cum oil production):
- Permeability (Kh & Kv)
- Aquifer parameters (Aquifer volume and strength).
- Relative permeability for Oil and end points.
For GOR :
- Vertical permeability.
- Relative permeability for gas.
- Check the GOC or GWC if any
- Check the Gas cap volume.
- Check the Gas PVT.
For Water Cut :
- Relative permeability for water.
- Aquifer parameters.
Generally speaking in the first trial you should assign the gross volume as a control node to match the pressure, then assign the oil rates as a control node to match the rest of other parameters.
