Convertible Autofill Float Equipment Having Poppet Valve and Sliding Sleeve

A method used for a tubing string in a wellbore, the tubing string having a throughbore for fluid flow, the method comprising:

• deploying the tubing string in the wellbore while allowing fluid flow in an upbore direction and a downbore direction through a bypass pathway of a float assembly in an opened state, the float assembly disposed on the tubing string and having a sleeve, at least one valve, and a shifting assembly, the sleeve disposed in the float assembly, the at least one valve disposed in the sleeve, the shifting assembly disposed in the sleeve and disposed downbore of the at least one valve;
• converting the bypass pathway of the float assembly from the opened state to a closed state by:
• pumping fluid flow in the downbore direction;
• restricting fluid flow pumped in the downbore direction through the shifting assembly;
• moving the sleeve in the float assembly from an opened condition to a closed condition relative to the bypass pathway of the float assembly in response to fluid flow pumped in the downbore direction to a first predetermined level;
• and
• closing off fluid communication of a bypass port in the sleeve with the bypass pathway in response to the sleeve moved to the closed condition;
• and
• permitting fluid flow only in the downbore direction through the at least one valve with the bypass pathway of float assembly in the closed condition.

A float assembly for use on a tubing string having a throughbore for fluid flow, the float assembly comprising:

• a housing configured to couple to the tubing string, the housing defining a housing bore therein communicating with the throughbore of the tubing string;
• a sleeve disposed in the housing bore and being movable from an opened condition to a closed condition relative to a bypass pathway defined in a space between the sleeve and the housing bore, the sleeve defining a flow passage and defining a bypass port, the bypass port with the sleeve in the opened condition being disposed in communication with the bypass pathway, the bypass port with the sleeve in the closed condition being disposed out of communication with the bypass pathway;
• at least one valve disposed in the flow passage of the sleeve, the at least one valve permitting fluid flow in a downbore direction and preventing fluid flow in an upbore direction;
• and
• a shifting assembly disposed at least partially in the flow passage of the sleeve, the shifting assembly being convertible between a first condition and a second condition, the shifting assembly in the first condition permitting fluid flow in at least the upbore direction, the shifting assembly in the second condition being configured to move the sleeve from the opened condition to the closed condition in response to fluid flow in the downbore direction above a first predetermined level.
