1. A method of controlling the fluid flow from a subsea well, comprising:

  • connecting at least two separate subsea blowout apparatus above different proximal end branches of a subsea multi-path apparatus, wherein said multi-path apparatus comprises at least two proximal ends that define separate injection conduits converging to a common distal end;

    connecting above the respective proximal end of at least one of said at least two separate subsea blowout apparatus at least one riser conduit wherein said riser conduit has a proximal end at or near the surface;

    inserting at least one injection conduit having a proximal end at or near the surface into at least one of said riser conduit;

    pumping fluids from the surface into said subsea well through the at least one conduit having a proximal end at the surface and a distal end below the surface, wherein different fluids are injected down the separate injection conduits through the separate subsea blowout apparatuses with said pumping from surface of said fluids.
