Resumen:

Application of type curves to interference testing has usually provided poor results due to match nan-uniqueness. In this paper, we present three new sets of type curves using the dimensionless pressure groups P D and the derivative of the dimensionless pressure versus the time function t DA IE/yE for case of an observation well in a rectangular reservoir. Three sets of type curves are generated for the case of the producing well at the corner, end or middle of the rectangular reservoir. The character of this set of type cunes, similar to Sourdet et al. type curves, provides a great improvement in obtaining a unique type curve match. Flow regimes covered in the analysis include infinite acting pressure response with wellbore storage and skin at both the active and observation wells as well as linear flow and pseudo-steady state flow. This study then explains the use of this new set of type curves for an interference test in a limited reservoir using the useful Bourdet et al. pressure derivative approach. A field example zs included to demonstrate the application of this method to actual test data and how cartesian methods can be used to verify the match. © Curran-Conference. All rights reserved.
