US Patent 7533732 Dual entry apparatus for a subterranean borehole

A borehole entry apparatus is disclosed. The apparatus includes a dual entry apparatus for use in borehole entry applications, such as slick line and/or wireline (electric wireline) applications. Exemplary embodiments of this invention enable first and second borehole entry apparatuses, such as slick line and wireline tool assemblies, to be simultaneously coupled to a well head. Use of the invention tends to advantageously save rig time and thus reduce the cost of slick line and wireline operations, in particular on a deep-water offshore drilling rig.
