Semianalytical Modeling of Nonconventional Well Performance in Realistic Reservoirs
Abstract/Contents
- Abstract
- The applicability of a semianalytical technique for the modeling of nonconventional wells in complex geological settings is assessed. The semianalytical approach, based on Green's functions, is extended through the development of an improved approximation for near wellbore heterogeneity. The basic heterogeneity model, referred to as the s-k* permeability representation, describes the permeability field in terms of a locally varying skin s and a global effective permeability k*. The model is extended in this work to account for varying anisotropy in the fine scale permeability field, to treat inactive cells within the permeability description and to tune the model parameters using reference finite difference solutions. A treatment for multiple reservoir facies is also introduced.Using three different geological settings involving more than one facies and/or facies dependent anisotropy ratio in the fine-scale permeability field, we validate the applicability of the extended s-k* representation to real field problems. Results obtained in this work suggest that the semianalytical approach with the new s-k* representation is a practical tool to model the performance of nonconventional wells in complex geological settings.
