... law exponential decline" method seems to be promising in predicting the production rate over both transient and BDF regimes. In this paper, we examine the applicability of the power law exponential decline for different cases. We evaluate its behavior during both the transient and boundary-dominated...

... in the waterflood life. However, that is not to say that exponential (b=0) or "super" exponential decline (b<0) never occur. When they do occur, usually non-reservoir factors are involved. This paper also shows how incremental oil recovery can be calculated using decline methods accounting for changes in fluid...

..., arbitrarily using an exponential decline approach (log(q o ) versus time assumed to be linear) for water drive, solution gas drive, and gravity drainage systems is neither technically nor empirically correct. Use of exponential decline during periods of increasing volumetric sweep efficiency will generally...
