Abstract
Official abstract text for this publication.
A convergent solution is provided for a coupled system where oil flow from a subsurface reservoir formation enters a number of pipes of a multi-branch well in the formation. An iterative linear system solver computer implemented methodology is developed, capable of handling a large number of unknowns which are present when modeling a multi-branch well. A systematic approach which defines proper boundary conditions at the reservoir level and at the wellhead is provided and utilized.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer implemented method of forming a model of fluid flow rates of a multilateral well in which fluid from a subsurface reservoir enters perforations in a plurality of pipes off a main bore of the well, the model being based on data measurements regarding the fluid, well and reservoir, and comprising the computer implemented steps of: determining an initial measure of transmissibility of the pipes based on the data measurements and on the pipes having f…
