ABSTRACT of Presentation

 

This presentation will discuss recent updates and progress regarding the use of a modified technique for extended exponential decline curve analysis, which is especially useful in shale reservoirs. In the original Arps paper on decline curve analysis (DCA), the b-factor of the hyperbolic equation was assumed to be a constant and limited to values less than or equal to 1.0.  However, many literature papers and field observations have shown that the b-factor changes with time in shale wells and, in many cases, can be well above 1.0. As a result, evaluators have modified the original DCA to incorporate a b-factor greater than 1.0 and a minimum exponential decline rate (Dmin) at the late-time.  Zhang, Rietz, and Lee, et. al presented the Extended Exponential Decline Curve Analysis (EEDCA) in 2015 as an alternative method with advantages to forecast shale well performance without requiring an a priori prediction of Dmin. It can also be used to calculate the transient b-factor over time and determine a value for Dmin.
