ABSTRACT:
A wye block apparatus provides selective physical access to multiple downhole tubing strings while permitting fluid communication with each of them. In a described embodiment, a wye block apparatus is resistant to malfunction due to debris therein, in substantial part by providing an elongated deflection member which is axially rotatable within an outer housing assembly. A J-slot device is utilized to rotate the deflection member in response to axial displacement of an operating sleeve. Rotation of the deflection member selectively aligns a guide surface formed on the deflection member with one of the tubing strings attached to the wye block apparatus.
