... very little mention of the implications of using NTG in flow equations within a reservoir simulator. The paper discusses the derivation and implied assumptions for the simulator NTG formulation and possible errors and proposes modifications to account for inconsistencies. Resolving the NTG flow...

We present an alternative approach in fractional flow theory in which the two-phase displacement problem is analyzed without invoking the shock assumption. The shock-free approach eliminates the triple...
