Apparatus (50, 51) and method for creating a hole (310) in a subsurface formation (305). An inner assembly (50), which may include a coring barrel (6), a piston cylinder (23) and a piston rod member (15), is connected to an elongate member (18) such as a wireline. The inner assembly (50) may include a member such as a packer (30) capable of engaging one of an outer assembly (51) and the borehole (200). Furthermore, the coring barrel (6) may have a cutting member (1, 6) for creating the hole (310) in the subsurface formation (305).

A core sampler, particularly for oil prospecting, including a coring bit (2), an outer barrel (3) for rotating the coring bit (2), and an inner barrel (5) for receiving the core sample (7) in its internal space (8) during coring, the inner (5) and outer (3) barrels being substantially coaxial, and further comprising an intermediate barrel (15) coaxially arranged between the inner (5) and outer (3) barrels and defining a first longitudinal coring fluid channel (16) with the outer barrel (3), and a second longitudinal coring fluid channel (17) with the inner barrel (5), as well as said longitudinal channels (16, 17) and means for at least temporarily selectively causing and/or cutting off coring fluid communication between the rear end (17B) of the second longitudinal channel (17) and/or the rear end (16B) of the first longitudinal channel (16) and/or the rear end (8B) of the internal space (8).
223 CORING ASSEMBLY AND METHOD EP94927337 1994-08-31 EP0715677A4 2001-04-04 ORMSBY RONALD D
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) are disposed along the inner core barrel (26) to provide a flow path for the drilling fluid after the restriction is formed. The bores are calibrated to produce a pre-determined hydraulic force on the inner barrel (26). A bearing assembly (30) is used to prevent transmission of outer barrel (12) rotation to the inner core barrel (26). The outer surface of the bearing assembly (30) forms the valve face (48) so as to form the drilling fluid restriction and also provides an axial stop that prevents further axial movement of the inner barrel (26) towards the core head (14).

A plurality of recesses (5B) are formed about an inner circumferential wall at one end of the drive sub (18) and a landing seat (32) formed about the inner wall upstream of the recesses (58). The area of the interior wall between the landing seat (32) and recesses (58) is profiled with a series of tapered and level surfaces. The tool (20) includes a slidable cradle (176) extending from one end about which the bit segments (22) are held during installation and retrieval. The bit segments (22) being held in place about the cradle by an elastic band (198). The insert (24) is provided at one end with a series of keyways (218) which locate over the bit segments (22) when the bit segments are locked to the drive sub (18). The insert (24) is always retained within the drive sub (18). Bit segments (22) are carried by the tool (20) to the drive sub (18) and locked in place by the insert (24). The tool (20) can then be withdrawn and the drill (12) operated in the normal manner. To retrieve the bit segments (22), the tool (20) is relowered into the drill and then withdrawn a short distance to retract the insert (24) so that the bit segments (22) collapse back onto the cradle (176) and can then be withdrawn from the drill (12).

235 A device in core barrels EP81850183.5 1981-10-07 EP0050104A2 1982-04-21 Eriksson, Sune Wilhelm

A device in core drilling for indicating when a core barrel placed in a rotatable hollow drill rod is no longer capable of receiving a further quantity of reamed-out core material includes a valve which at said condition of the barrel constricts the passage for flushing medium flowing between the core barrel and the bore of the drill rod so that a readable flushing medium pressure increase occurs. The valve closes off said passge incompletely to allow a minor quantity of flushing medium to be taken to the drill bit mounted at the bottom of the drill rod, thereby to prevent said drill bit from being burnt out.
