[54] AUTOFILL AND CIRCULATION ASSEMBLY AND METHOD OF USING THE SAME
[57] Abstract: A wellbore system comprising an autofill and circulation assembly comprising a housing defining a flowbore and comprising a first port and a second port, and a first sleeve slidable within the housing from a first position to a second position and from the second position to a third position, when the first sleeve is in the first position, the assembly allows fluid communication from an exterior of the housing to the flowbore via the first port and does not allow fluid communication from the flowbore to the exterior of the housing via the first port, when the first sleeve is in the second position, the assembly allows bidirectional fluid communication between the exterior of the housing and the flowbore via the second port, and, when the first sleeve is in the third position, the assembly disallows fluid communication between the exterior of the housing and the flowbore.
