A manifold device connects in series between the wellhead and the outer casing of a well for providing access to the outer casing of the well without removing the wellhead. The device includes a tubular body for receiving the tubing string of the well therethrough. Plural access passages are formed in the tubular body to extend generally in the longitudinal direction of the body between an external end which is spaced radially from the hollow interior of the tubular body and an internal end converging in communication with the hollow interior at the bottom end of the manifold device. Well servicing tools can be inserted into the casing annulus defined between the outer casing and the tubing string of the well through one of the access passages formed in the tubular body of the manifold device.
