Abstract
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.
