Abstract
An Internal Bottom Hole Assembly (IBHA) for a Coiled Tubing (CT) enables the CT to be used with other devices downhole. The IBHA includes a connector, a valve assembly and an emergency disconnect device, all of which are mounted internally in the CT. The connector couples to the inside of the CT by means of wedges that are urged against the inside wall of the CT. The valve assembly may be mounted either between the connector and the disconnect device or may be on the side of the connector away from the disconnect device. The valve assembly includes one or more flapper valves that are able to pass a ball through at a minimum flow rate of fluid, enabling the ball to be used to operate the disconnect device.
