need urgent help on history Match

Post by petro »

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.

Hello adrian,
Unfortunately, sorry.

I really can't share it.

What do you think if we share a simple model for discussion.

Let me search for an appropriate one for both of you and for all members to discuss the influence of these factors on the history match.
