An improved downhole well control tool (“WCT”) allows for the control of in-situ fluid flow from a production well having one or more production zones. The WCT is installed in a tubing string in a zone to be controlled. A ported seal stem having an orifice of a size and shape to provide the desired choking is seated in the WCT using wireline tools to allow for the production of oil and/or gas. The WCT has an orientation sleeve that causes the seal stem to rotate and align the orifice with a port in the WCT. The seal stem may be removed to fully-open the port of WCT for injection operations, or a non-ported seal stem may be seated in the WCT to seal off the zone. WCTs of different diameters allow for multiple zones to be controlled.
