In this paper, an extension of the multi-scale finite-volume (MSFV)
method is devised, which allows to Simulate flow and transport in
reservoirs with complex well configurations. The new framework fits
nicely into the data Structure of the original MSFV method,and has the
important property that large patches covering the whole well are not
required. For each well. an additional degree of freedom is introduced.
While the treatment of pressure-constraint wells is trivial (the
well-bore reference pressure is explicitly specified), additional
equations have to be solved to obtain the unknown well-bore pressure of
rate-constraint wells. Numerical Simulations of test cases with
multiple complex wells demonstrate the ability of the new algorithm to
capture the interference between the various wells and the reservoir
accurately. (c) 2008 Elsevier Inc. All rights reserved.
