Abstract: Coring apparatus (10) and method are disclosed which provide for hydraulic latching of an inner core barrel (26) within an outer core barrel (12). The apparatus includes a valve face (48) disposed around the inner core barrel (26) and valve seat (52) disposed around the bore of the outer core barrel (12) that close to form a restriction in drilling fluid flow path (54). A hydraulic differential force is thereby created which holds the inner barrel (26) in place. Axially oriented bores (64) in a hanger assembly (58) and in stabilizers (62) ace disposed along the inner core barrel (26) to provide a flow path for the drilling fluid after the restriction is formed.
