# Crude Oil Velocity Flow Within Rock-Soil Matrix

In order to run some numerical simulations, I would like to know some rough values (estimates) of the velocity at which the crude oil flows through the rock or soil matrix from which it is extracted. I found lots of data about production rates (bpd), which is the main parameter of interest from the engineering point of view, but so far, nothing about this technical aspect. One last thing, I am an outsider (civil engineer and applied mathematician), not an specialist.

• Search for interstitial velocity. A ballpark number is $10^{-5}$ m/s. – Biswajit Banerjee Oct 25 '15 at 5:50
