Patent ID: 8321190

Claim:
A method of simulating fluid transport in a system for enhancing productivity of a well in a material formation of a resource reservoir, the system comprising a conduit element arranged in said well, the conduit element comprising a conduit wall including one or more openings for discharging a fluid into the material formation surrounding the conduit element; the method comprising establishing and numerically processing a transport model of fluid transport inside the conduit element; wherein the method comprises establishing a transport model of longitudinal fluid transport along a longitudinal axis of the conduit and of lateral fluid transport away from said longitudinal axis into the material formation, wherein the transport model includes a grid of volume cells; characterized in that the transport model further includes a model of fluid transport in a predetermined annulus space around said conduit element between the conduit element and the formation for modeling displacement of mud by acid; and that the grid of volume cells includes cells of a number of different cell types including a first type of cells representing the conduit element and a second type of cells representing the annulus space around said conduit element, and wherein the transport model includes respective, local models for modeling fluid flow between adjacent volume cells.
