Claim 10:
11. A method for placing a fluid in an annulus of a well, the method comprising:
providing a casing string having a casing outer circumferential surface that delineates a boundary of the annulus, wherein the casing string further comprises a flow control apparatus having:
a tubular body having a conduit delineated by a tubular inner circumferential surface, a first end, and a second end, wherein the first end is connectable to the casing string and the conduit comprises a hydraulic connection with the annulus in a second direction;
a float valve, fixed within the conduit of the tubular body, configured to block flow in a first direction and allow flow in the second direction;
a disk, fixed above the float valve and within the conduit of the tubular body, configured to prevent flow in the second direction until the disk is broken by a pre-determined force;

filling the casing string with a fluid while running the casing string into the well;
running a stinger, using a deployment device, into the conduit of the tubular body;
applying the pre-determined force to the disk to break the disk using the stinger; and
pumping a fluid, in the second direction, from the stinger to the annulus.
