Hi guys,

I am working with linear flow reservoirs at the moment, and I have been using the conventional oil rate transient approach to estimate reservoir properties, etc. These equations, however, are based only on oil flow and do not consider a second phase (gas) nor a third (water)

I'm wondering if any of you know of a method similar to 1-phase rate transient, that can give me information about a reservoir producing oil gas and water. In other words, are there any rate transient methods for multiphase flow?

Thanks.
