The present invention relates to a drill tool for rotary and/or percussive drilling comprising a central pilot bit (12) and a, in the feed direction of the tool, behind the pilot bit located eccentric reamer (11; 11′) that via guide means (10) is connected to a drill string that is rotatably coupled to a drill machine, said drill string and the guide means (10) being at least partially surrouned by a casing tube (15). The drill tool also comprises means to supply flush medium and means to remove flush medium and cuttings. The characterizing for the invention is that the reamer (11; 11′) is driven through a co-operation between a tongue (21; 21′) and a shoulder (22,24; 22′,24′), said tongue (21; 21′) can be located either on a portion (16) that receives the reamer (11) or on the reamer (11′) itself and the shoulders (22,24; 22′,24′) either on the reamer (11) or the portion (16′) that receives said reamer (11′). |

| A casing-while-drilling bottom hole assembly is releasably connected with a casing string. A retrieval tool is run into the casing string and latched to the bottom hole assembly. Slips are mounted to the retrieval tool, the slips being retracted during running in. Differential pressure moves the retrieval tool and bottom hole assembly upward, and the slips engage the casing string to prevent downward movement if the pressure differential drops too low. A flow passage extends through the retrieval tool and the bottom hole assembly. A check valve in the retrieval tool allows downward flow through the flow passage but prevents upward flow, so that fluid may be circulated through the retrieval tool and bottom hole assembly while suspended with the slips. | ||||||

| A liner drilling system employs a bottom hole assembly that may be retrieved before reaching the total liner depth. The system includes an outer string made up of a liner and a profile nipple. An inner string including a running tool, drill pipe, and a drill lock tool are lowered into the outer string and rotationally and axially locked to the outer string. Drilling may be performed by rotating the inner string, which also rotates the outer string. The operator may retrieve the inner string by pulling the inner string and the liner upward until the upper end of the liner is located at the drilling rig floor. While supporting the liner at the drilling rig floor, the operator retrieves the inner string, then re-runs it back into the outer string. | ||||||

| A method and apparatus for conducting earth borehole operations include a reel (28) of continuous coiled casing (30), and an injector (20) for moving the coiled casing. The bottomhole assembly including at least a motor (54) and a bit (56) is connected to the free end of the coiled casing, and injected into the earth while circulating fluid through the coiled casing to form a drilled earth borehole having a borehole wall. The coiled casing drill string may be retrieved from the borehole, the bottomhole assembly removed, and the coiled casing again injected into the borehole, then suspended from a wellhead assembly. After severing the coiled casing, a bonding agent such as a cementitious material may be injected into the suspended coiled casing and into the annulus between the coiled casing and the borehole. | ||||||

| 117 | Expandable bit | US10526360 | 2003-09-05 | US20060096785A1 | 2006-05-11 | Bruno Walter; Per Angman |
| A bit has been invented that is expandable from a collapsed position, useful for tripping, to an radially expanded position for use. The bit is useful to form a borehole through an earthen formation. In one embodiment, the bit can be used alone, without a separate under reamer, to expand a well bore below a casing string, either during casing drilling or when extending a well bore below an installed casing string. The bit cutter face includes a center cutter face on a mandrel and an outer cutter face mounted on an expandable section of a housing disposed about the mandrel. The outer cutter face can be expanded by axial movement of the mandrel within the housing. | ||||||
| 118 | Reverse circulation drilling system with bit locked underreamer arms | US09702277 | 2000-10-30 | US06394197B1 | 2002-05-28 | Ardis L. Holte |
| A underreamer drill bit assembly including a pilot bit and extendable underreaming arms operatively connected to the pilot bit. The underreaming arms have an extended position for underreaming, and a retracted position in which the overall diameter of the underreamer drill bit assembly is less than the inside diameter of the well casing, permitting the entire bit assembly to be withdrawn through the well casing. In another aspect of the invention, the bit assembly is operatively connected to a dual wall pipe assembly. A supply of compressed air is conducted through the annulus of the dual wall pipe assembly to a down hole pneumatic hammer. Exhaust air from the down hole hammer is directed to the bit assembly for continuous removal of drilling debris through a central evacuation tube of the dual wall pipe assembly. In another aspect of the invention, a pressurized, incompressible fluid is injected into the annulus between the well casing and the downhole pneumatic hammer. | ||||||

| A drilling tool for boring in earth and rock formations includes a pilot bit which defines a longitudinal tool axis and includes a cam part having a cam axis arranged eccentrically relative to the tool axis. A reamer includes a hollow reamer body mounted on the cam part for rotation relative thereto about the cam axis. Relative rotation in one direction causes the reamer to be radially extended, and relative rotation in an opposite direction causes the reamer to be radially retracted. The reamer body carries cutting elements for enlarging a hole drilled by the pilot bit when the reamer is in its extended position. The cam part carries a first removable insert on which a first stop surface is formed. The reamer carries a second removable insert on which a second stop surface is formed. The stop surfaces are engageable with one another when the reamer body is radially extended, for transmitting rotational cutting forces to the reamer. The stop surfaces are formed of a material harder than a material from which the cam part and the reamer body are formed. The stop surface of the insert carried by the reamer may be formed by a plurality of rotary ball bearings. | ||||||

| A retractable drill bit system (10) comprises a drive sub (18) which is adapted for connection to a lower end of a drill (12), a tool (20) for installing and retractable drill bit segments (22) from the drive sub (18); and an insert (24) for selectively locking the bit segments (22) to an end of the drive sub (18) and releasing the bit segments (22). 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 receive 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). | ||||||
