A slender-body theory is developed for the axisymmetric Darcy flow from a large reservior to an isolated well bore. The resulting analysis serves to eliminate from the standard petroleum-engineering formula: [image omitted] the generally undefined parameter re, representing fictitious distance from an injection or production well to the undisturbed reservoir. In particular, we show that, upon equating re, to the well length l, one can interpret the above formula as an exact asymptotic result under fairly general circumstances including variations of the local well-bore pressure pw and radial injection velocity v0 with axial position. We also present higher-order corrections to the asymptotic result, in terms of the well slenderness ratio re/l, by making use of a previous perturbation analysis of Handelsman and Keller (1967) for axisymmetric potential flow. Our results have application to other problems involving the potential field around slender sources. |
