A practical nonlinear regression technique for horizontal well test interpretation Academic Article

abstract

• A practical nonlinear regression technique for analysis of horizontal well pressure transient tests is presented. This technique can provide accurate and reliable estimation of well-reservoir parameters if downhole flow rate data are available. In situations without flow rate measurement, reasonably reliable parameter estimation can be achieved by using the detected flow rate from blind deconvolution. This technique has the advantages of eliminating the need for estimation of the wellbore storage coefficient and providing reasonable estimates of effective wellbore length. It provides a practical tool for enhancement of horizontal well test interpretation, and its practical applicability is illustrated by synthetic and actual field cases.
