Streamlines are unique in allowing determining drainage volumes associated with producers or irrigation volumes associated with injectors. Furthermore, since streamlines change with time it is possible to display and quantify the changing volumes associated with each well as well rates change and/or new wells come online.

(above) Streamlines connected to producer WW2 defining the drainage volume associated with the producer at that a particular moment in time. The drainage volume is found by finding all the gridblocks of the underlying static Eulerian grid that are being intersected by the all the streamlines associated with producer WW2.

(above) Streamlines connected to injector WW4 defining the irrigation volume associated with the injector at that a particular moment in time. The irrigation volume is found by finding all the gridblocks of the underlying static Eulerian grid that are being intersected by the all the streamlines associated with injector WW4.
