... Abstract Conventional DCA methods, developed for boundary dominated flow (BDF), yield unrealistic values for expected ultimate recovery (EUR) when used for unconventional reservoirs with long-duration transient linear flow. Moreover, the developed model parameters are not functions of reservoir...

... such as the decline exponent and time to boundary dominated flow are discussed and compared between wells. Differences in well design such as well length and proppant tonnage impact the well performance and are covered in this paper with a suggested methodology for normalizing the performance data. Finally, a key...

... horizontal wells since 2006. Reported production data enables comparisons of well performance during these eras. This study employs the log-log graph of rate (q) versus material balance time (Q/q) to diagnose transient (slope −¼ or −½) and boundary dominated flow (BDF) (slope −1) behavior. Wells from the 3...

... Abstract Analysis of flow rate and pressure data, relies on the solution derived using the "constant rate" boundary condition. However, most of the time, production rates are variable. Therefore, superposition (convolution) must be used to make variable rates look like their equivalent constant...

For conventional gas reservoirs, the average reservoir pressure was utilized to evaluate pseudotime and worked very well during boundary...

The results, presenting in a type curve format under various conditions, have shown that SRV region is strongly related to the fracture influenced/dominated boundary flow regime and appears as a region possessing a less than 1 slope in pressure and reciprocal rate derivative curves, which indicates...

This agreement shows that analyzing the late time pseudosteady state data (boundary dominated flow regime) complements the linear transient analysis. Specifically, the proposed pseudosteady...

Shear deformation or changes in total stresses, and the resulting stress re-distribution in the reservoir, can be caused by non-uniform reservoir flows; boundary, corner and arching...

... Abstract The evaluation of Expected Ultimate Recovery (EUR) for tight gas wells has generally relied upon the Arps equation for Decline Curve Analysis (DCA) as a popular approach. However, it is typical in tight gas reservoirs to have limited production history that has yet to reach boundary...
