When Core data is not availiable!

[rhosseiny]

Dear Engineers,
we are going to simulate a reservoir which doesn't have any core data! (resistivity log is available).
did you encounter in this situation yet?
do you have any idea to solve this problem?

Regards

rhosseiny;
This a usual case in simulation, you can build the model but with so high uncertainty and it depends on the history match you will get and it depend mainly on the understanding of your reservoir and the available data, so if the core data is the only unavailable data, it can be a matching parameter but in this case you have to decide which matched model is satisfying your experience.

i'd like to talk this topic with you,
firstly i want to ask you one question ,core data is unavailable, so you dont have relative permeability curve,
it is easy to use nearby reservoir curve
any other purposes?

Rel-perm curves on analogy might work, if the homogeneity extends beyond your lease area; but like the post above correctly states, the output of the model would still need to satisfy the oilman's nose

Dear Rhosseiny, some avices for your model:

1. Populating Porosity and Permeability: For terrigenous rocks use Nelson's catalog available at the following website:

[link Point to another website Only the registered members can access]
2. Relative Permeability: refer to Hornapour's book "Relative permeability of petroleum reservoirs", there you can find various correlations for calculating 2-phase and 3-phase kr. You could also use petrography and Burdine's theory on paper SPE 225-G "Relative perm calculations from pore size distribution data".

3. Capillary Pressure data: it is a function of pore-throat size and some other parameters. Just look for some correlations based on pore-throat size (determined from drill cuttings).

I hope this helps.

there is some empirical relationship to determine the relative permeabilities which functons of initial water saturation, instantaneous water saturation and residual oil saturation so in case of no core data available you can use these equations.
thanks
