  • FLOAT VALVE PRODUCING TURBULENT FLOW FOR WET SHOE TRACK
    Publication number: 20240344425
    Abstract: A float tool is used for controlling flow in tubing. The float tool comprises a housing, at least one valve, and at least one inset. The housing is configured to install on the tubing and has a longitudinal bore therethrough. The at least one valve is disposed in the longitudinal bore. The at least one valve is configured to allow the flow in a downbore direction through the longitudinal bore and is configured to prevent flow in a upbore direction through the longitudinal bore. The at least one inset is disposed in the longitudinal bore and is disposed downbore of the at least one valve. The at least one inset defines an orifice therethrough. The orifice has one or more vanes angled relative to the longitudinal bore. The one or more vanes are configured to produce turbulence in the flow in the downbore direction through the longitudinal bore.
