Claim 0:
1. A system for placing a fluid in an annulus, the system comprising:
a casing string with a casing outer circumferential surface, wherein the casing outer circumferential surface delineates a boundary of the annulus;
a flow control apparatus comprising:
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, and
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; and

a stinger, deployed in the casing string by a deployment device, having a bottom end with an outer diameter smaller than a diameter of the conduit,
wherein the stinger applies the pre-determined force to the disk to allow a flow of the fluid, in the second direction, from the stinger to the annulus.
