.... If a maximum injection rate constraint is defined, the well(s) might have to be choked back via a surface choke (as illustrated in Figure 2 ) to obtain a wellhead pressure low enough to respect that constraint. But this low wellhead pressure will force the wellhead flowing conditions towards CO 2...

... to the same location under wellhead pressure. A novel separation and pumping system has been conceived which allows an integrated separator and pump to be installed within a conventional 30" conductor in a dummy well. This novel configuration has been called VASPS (Vertical Annular Separation and Pumping...
