    Abstract: An assembly for use to cement an uncased wellbore and create a sidetrack of a wellbore with a single trip into the wellbore. The assembly includes a mill selectively connected to a whipstock. A snorkel tube is positioned within a bore of the mill and within a bore of the whipstock. The assembly is connected to drill string and positioned within an openhole portion of the wellbore. After the assembly has been anchored, cement may be pumped down the drill string and through the snorkel tube. The mill may be removed from the whipstock by shearing a shearable device connecting the mill to the whipstock. The mill is used engage a diverting surface on the whipstock and create a sidetrack. The mill may also mill a portion of the snorkel tube or the snorkel tube may be removed from wellbore up the drill string prior to milling the sidetrack.

    Abstract: A tubular string is run into a wellbore with a remotely actuated valve near a lower end adjacent a cementing shoe. The valve is triggered to operate without intervention such as by mud pulses generated at the surface and recognized by a sensor linked to a processor adjacent the valve to trigger the valve to close. Alternative actuation systems are envisioned for the valve that is located near the cementing shoe.
