... pressure and pressure derivative. The flow regimes include wellbore storage, transition flow from wellbore storage to cave storage, wave propagation and fluid flow in cave, formation flow. The four regimes can be used to characterize the features of fluid fow in carbonate reservoirs with caves. All of wave...

... inversion. This study presents a new way to numerically simulate flow of slightly compressible fluid which is solved rigorously with wellbore storage and skin. This paper shows that the use of Orthogonal Collocation method is feasible and that, in many cases, it results in solutions that are more realistic...
