Integrated milling and production device and method

An integrated milling and production device includes a production housing having a central bore, one or more flapper valves pivotally disposed within the central bore, and an actuator disposed within the central bore. The flapper valves are closed in a default position. Activation of the actuator permanently opens the one or more flapper valves. A connector is selectively secured below the production housing, a motor is secured below the connector, and a milling bit is secured below the motor. The motor rotates the milling bit. Activating the connector disconnects the connector from the production housing. The actuator may be a piston disposed above the flapper valves in a milling position and disposed through the flapper valves in a production position to open the flapper valves. In the production position, a fluid may flow from the wellbore through the production housing's central bore and to the surface for collection.
