Definitions
- This invention relates generally to oil and gas exploration, and in particular to forming and repairing wellbore casings to facilitate oil and gas exploration.
- a relatively large borehole diameter is required at the upper part of the wellbore.
- Such a large borehole diameter involves increased costs due to heavy casing handling equipment, large drill bits and increased volumes of drilling fluid and drill cuttings.
- increased drilling rig time is involved due to required cement pumping, cement hardening, required equipment changes due to large variations in hole diameters drilled in the course of the well, and the large volume of cuttings drilled and removed.
- the present invention is directed to overcoming one or more of the limitations of the existing procedures for forming and/or repairing wellbore casings.
- a cutter for an expandable wellbore casing is provided.
- FIG. 1 shows a schematic fragmentary cross sectional illustration of a casing cutter tool in a wellbore casing, with the cutter tool in a retracted non-cutting configuration and at a location in the wellbore casing below an overlapping joint between an expanded upper casing section and a partially expanded lower section that are joined together at an overlapping joint in a nested arrangement to form a mono diameter wellbore casing according to one aspect of the invention.
- FIG. 2 shows a schematic fragmentary cross sectional illustration of the casing cutter tool of FIG. 1 in an expanded cutting configuration according to one embodiment of the invention.
- FIG. 3 shows a schematic fragmentary cross sectional illustration of the casing cutter tool of FIG. 2 with an actuation device shown in a configuration for expanding cutter blades radially outward into a cutting position.
- FIG. 4 shows a schematic fragmentary cross sectional illustration of the casing cutter tool of FIGS. 1-3 raised to a location in the expanded portion of the lower wellbore casing for engaging with an unexpanded portion of the lower casing that projects above the overlapping joint of the upper and lower wellbore casing sections.
- FIG. 5 shows a schematic fragmentary cross sectional illustration of the casing cutter tool of FIGS. 1-4 further raised in the wellbore casing and rotated with radially projecting cutter blades engaged with the unexpanded portion of the lower casing.
- FIG. 6 shows a schematic fragmentary cross sectional illustration of a casing cutter tool of FIGS. 1-5 with radially projecting cutter blades severing the unexpanded portion of the lower casing and with the severed portion supported by the cutter tool for lifting it out of the wellbore.
- FIG. 7 shows a schematic fragmentary cross sectional illustration of a casing cutter tool with an actuation device shown in a configuration for retracting cutter blades radially inward into a non-cutting position.
- FIG. 8 shows a cross-section through an exemplary embodiment of the expander device for a cutter tool with cutter blades of the cutter tool in an expanded cutting position.
- FIGS. 1-5 illustrate several illustrative embodiment of a cutter tool 10 in a wellbore 12 for forming a mono diameter wellbore casing 14 and the method of using the cutter tool 10 .
- the invention is implemented using the methods and/or apparatus disclosed one or more of the following: (1) U.S. patent application Ser. No. 09/454,139, attorney docket no. 25791.03.02, filed on Dec. 3, 1999, (2) U.S. patent application Ser. No. 09/510,913, attorney docket no. 25791.7.02, filed on Feb. 23, 2000, (3) U.S. patent application Ser. No. 09/502,350, attorney docket no. 25791.8.02, filed on Feb. 10, 2000, (4) U.S. Pat.
- FIG. 1 shows a casing cutter tool 10 in a wellbore casing 14 in a wellbore 12 .
- the cutter tool 10 in a retracted non-cutting configuration and at a location in the wellbore casing 14 below an overlapping joint 16 between an expanded upper casing section 18 and a partially expanded lower section 20 .
- the expanded upper casing section 18 and the partially expanded lower section 20 are in a nested arrangement.
- the lower section 20 has been expanded into a bell portion 22 formed in the upper expanded section 18 of the wellbore casing 14 , thereby forming the overlap joint 16 in preparation for cladding to seal together the upper and lower casing sections 18 and 20 .
- the lower section 16 of casing 14 has an extra portion 24 extending upward into the upper casing section 18 a distance greater than is required for forming an adequate joint 16 .
- the bell portion 22 may be preformed, before the lower casing section 20 is expanded, or may be formed at the same time as the lower casing section 20 is expanded. Where the upper casing section 18 is not previously expanded to form a bell portion 22 , expanding the lower section 20 at an overlapping joint 16 would require a significant amount of force and work to expand both the lower casing section 20 and the upper casing section 18 at the same time. Where the expanded bell portion 22 has been previously formed in the upper casing section 18 , the subsequent expansion of the lower casing section 20 does not require significantly more force at the joint 16 .
- a preformed bell portion 22 facilitates the process. Whether or not the bell portion 22 is pre-formed or formed upon expansion of the lower section 20 , it has been found by applicants by providing the cutter tool 10 of the present invention, the expansion of the lower casing section 20 may be terminated after a sufficient length of overlapping joint 16 is formed. This will leave an extra unexpanded portion 24 .
- the cutter tool 10 of the present invention is useful to cut off and remove the unexpanded extra portion 24 of the lower casing section 20 . Time and effort need not be expended to expand the extra portion 24 of the lower section 20 . Time and effort to carefully calculate and position each next lower section is also saved by simply choosing to always leave a sufficient extra length for the extra portion, knowing that it can be conveniently removed with the cutter tool 10 of the present invention.
- the cutter tool 10 is a modular device including a tubular support 28 that can be attached at a conventional upper coupling 30 axially aligned with a conventional drill pipe or other portion of a down hole string (not shown).
- a conventional upper coupling 30 axially aligned with a conventional drill pipe or other portion of a down hole string (not shown).
- other conventional tools, other conventional expansion tools or other tubular expansion tools as described in patents and co-pending patent applications incorporated above by reference may be connected at a conventional lower coupling 32 .

- a torsional force transmitter device 46 is provided to transmit rotational forces between the tubular support 28 and the cutter blades 34 .
- the interleave dummy blades also facilitate maintaining the proper orientation of the cutter blades 34 and transmission of rotational forces there between.
- the expander cone 44 is supported for axial sliding on a mandrel portion 48 of the tubular support 28 and is axially movable relative to the cutter blades 34 .
- An actuator 50 is provided that is selectively activateable to move the expander cone 44 axially along the mandrel portion 48 so that each ramp surface 40 is moved in ramping engagement with the interior surfaces 42 of each blade 34 .
- the actuator 50 may be a conventional device for actuating relative axial motion between sliding portions of down hole tools. The relative axial movement causes cutting tips 52 of the cutter blades 34 to pivot radially outward to the cutting position.
- the cutting tips 52 of the plurality of cutter blades 34 will define a cutting diameter D that is smaller than the expanded inside diameter ID 2 of the lower casing 20 and larger than the unexpanded inside diameter ID 1 of the extra portion 24 of the lower casing 20 .
- the actuator 50 includes a hydraulic device coupled to the expander cone 44 to move the ramp surfaces 40 relative to the cutter blades 34 .

- the opening dart 76 A can be blown out with increased fluid pressure and a closing dart 76 B can be injected to seat at seat 82 .
- the closing dart 76 B provides a relief passage 92 axially aligned with the opening port 68 and annulus 84 to permit escape of fluidic material from the opening chamber 62 so that pressure therein is reduced.
- a closing passage 94 is aligned with the closing port 72 and annulus 88 to provide fluidic material 78 into the closing chamber 64 so that pressure therein is increased.

- This invention relates generally to oil and gas exploration, and in particular to forming and repairing wellbore casings to facilitate oil and gas exploration.
- Conventionally, when a wellbore is created, a number of casings are installed in the borehole to prevent collapse of the borehole wall and to prevent undesired outflow of drilling fluid into the formation or inflow of fluid from the formation into the borehole. The borehole is drilled in intervals whereby a casing which is to be installed in a lower borehole interval is lowered through a previously installed casing of an upper borehole interval. As a consequence of this procedure the casing of the lower interval is of smaller diameter than the casing of the upper interval. Thus, the casings are in a nested arrangement with casing diameters decreasing in downward direction. Cement annuli are provided between the outer surfaces of the casings and the borehole wall to seal the casings from the borehole wall. As a consequence of this nested arrangement a relatively large borehole diameter is required at the upper part of the wellbore. Such a large borehole diameter involves increased costs due to heavy casing handling equipment, large drill bits and increased volumes of drilling fluid and drill cuttings. Moreover, increased drilling rig time is involved due to required cement pumping, cement hardening, required equipment changes due to large variations in hole diameters drilled in the course of the well, and the large volume of cuttings drilled and removed.
- The present invention is directed to overcoming one or more of the limitations of the existing procedures for forming and/or repairing wellbore casings.
- According to one aspect of the present invention, a cutter for an expandable wellbore casing is provided.
-

FIG. 1 shows acasing cutter tool 10 in awellbore casing 14 in awellbore 12. Thecutter tool 10 in a retracted non-cutting configuration and at a location in thewellbore casing 14 below an overlapping joint 16 between an expandedupper casing section 18 and a partially expandedlower section 20. The expandedupper casing section 18 and the partially expandedlower section 20 are in a nested arrangement. Thelower section 20 has been expanded into abell portion 22 formed in the upper expandedsection 18 of thewellbore casing 14, thereby forming the overlap joint 16 in preparation for cladding to seal together the upper andlower casing sections lower section 16 ofcasing 14 has anextra portion 24 extending upward into the upper casing section 18 a distance greater than is required for forming an adequate joint 16. Thebell portion 22 may be preformed, before thelower casing section 20 is expanded, or may be formed at the same time as thelower casing section 20 is expanded. Where theupper casing section 18 is not previously expanded to form abell portion 22, expanding thelower section 20 at an overlapping joint 16 would require a significant amount of force and work to expand both thelower casing section 20 and theupper casing section 18 at the same time. Where the expandedbell portion 22 has been previously formed in theupper casing section 18, the subsequent expansion of thelower casing section 20 does not require significantly more force at the joint 16. Thus, a preformedbell portion 22 facilitates the process. Whether or not thebell portion 22 is pre-formed or formed upon expansion of thelower section 20, it has been found by applicants by providing thecutter tool 10 of the present invention, the expansion of thelower casing section 20 may be terminated after a sufficient length of overlapping joint 16 is formed. This will leave an extraunexpanded portion 24. Thecutter tool 10 of the present invention is useful to cut off and remove the unexpandedextra portion 24 of thelower casing section 20. Time and effort need not be expended to expand theextra portion 24 of thelower section 20. Time and effort to carefully calculate and position each next lower section is also saved by simply choosing to always leave a sufficient extra length for the extra portion, knowing that it can be conveniently removed with thecutter tool 10 of the present invention. - In the exemplary embodiment illustrated, the
cutter tool 10 is a modular device including atubular support 28 that can be attached at a conventionalupper coupling 30 axially aligned with a conventional drill pipe or other portion of a down hole string (not shown). Similarly other conventional tools, other conventional expansion tools or other tubular expansion tools as described in patents and co-pending patent applications incorporated above by reference, may be connected at a conventional lower coupling 32. In the illustrated embodiment of thecutter tool 10,cutter blades 34 are expandably attached circumferentially space around thetubular support 28. Anexpander device 36 is attached to the tubular support for selectively moving thecutter blades 34 to expand or to retract. - With reference to
FIGS. 1 and 2 , the operation of theexpander device 36 is shown for expanding thecutter blades 34 from a non-cutting position with thecutter blades 34 retracted radially inwardly (as shown inFIG. 1 ) to a cutting position with thecutter blades 34 expanded radially outwardly (as shown inFIG. 2 ). Conventional mechanisms for radially expanding tools from a shaft or tubular member may be used to causecutter blades 34 to move to and from the cutting position. Dummy blades 37 (hidden from view inFIGS. 1-6 ) are provided positioned circumferentially around thetubular support 28 and interleaved with thecutter blades 34. In the illustrated embodiment, thecutter blades 34 are pivotably attached to thecutter tool 10 at apivot connection 38 and the dummy blades are pivotably attached at apivot connection 39. Theexpander device 36 includes aramp surface 40 for sliding engagement with aninterior surface 42 of each of thecutter blades 34. Anupper expander cone 44 is provided having a plurality of ramp surfaces 40 for sliding engagement with theinterior surfaces 42 of each of the circumferentially spacedcutter blades 34. A torsionalforce transmitter device 46 is provided to transmit rotational forces between thetubular support 28 and thecutter blades 34. The interleave dummy blades also facilitate maintaining the proper orientation of thecutter blades 34 and transmission of rotational forces there between. Theexpander cone 44 is supported for axial sliding on amandrel portion 48 of thetubular support 28 and is axially movable relative to thecutter blades 34. Anactuator 50 is provided that is selectively activateable to move theexpander cone 44 axially along themandrel portion 48 so that eachramp surface 40 is moved in ramping engagement with theinterior surfaces 42 of eachblade 34. It will be understood that theactuator 50 may be a conventional device for actuating relative axial motion between sliding portions of down hole tools. The relative axial movement causes cuttingtips 52 of thecutter blades 34 to pivot radially outward to the cutting position. In the cutting position, the cuttingtips 52 of the plurality ofcutter blades 34, will define a cutting diameter D that is smaller than the expanded inside diameter ID2 of thelower casing 20 and larger than the unexpanded inside diameter ID1 of theextra portion 24 of thelower casing 20. - In the illustrative embodiment, shown in greater detail in
FIG. 3 , theactuator 50 includes a hydraulic device coupled to theexpander cone 44 to move the ramp surfaces 40 relative to thecutter blades 34. When theactuator 50 is activated to “open”, thecutter blades 34 are moved to the cutting position and when theactuator 50 is activated to “close”, thecutter blades 34 are retracted position to the non-cutting position. Theactuator 50 has acylinder 54 and anopening piston 56 coupled to a slidingsleeve 58 that slides relative to themandrel 48 and engages theexpander cone 44. Adivider ring 60 is secured to themandrel 48 for sliding within thecylinder 54 and forms an openingchamber 62 on one side of thedivider ring 60, toward theopening piston 56, and aclosing chamber 64 on the other side of thedivider ring 60, toward aclosing piston 66. Theclosing piston 66 is coupled to the slidingsleeve 58 that engages theexpander cone 44 and slides relative to themandrel 48. Anopening port 68 extends between the openingchamber 62 and an up-stream fluid passage 70 through the interior of themandrel 48. A closingport 72 extends between the closingchamber 64 and adownstream fluid passage 74 in the interior of themandrel 48. - An
activation device 76 is provided, for example, the activation device may include anopening dart 76A, that is ported to directfluidic material 78 into and out of the opening andclosing chambers dart 76 provides and entryfluidic passage 80 that is in fluid communication with theupstream fluid passage 72, and seats at seat 82 within theupstream fluid passage 72 axially aligned with the openingport 68 and anannulus 84 to provide a path forfluidic material 78 into theopening camber 62, regardless of the rotational orientation of theopening dart 76A. Anexit fluidic passage 86 is also provided in theopening dart 76A. When the opening dart seats at seat 82, thefluidic passage 86 becomes aligned with the closingport 72 and anannulus 88 for allowingfluidic material 78 to escape from the closingchamber 64, and into thedown stream passage 74 in the interior of themandrel 48. Thus, a differential pressure results and theopening piston 56 is moved. Movement of theopening piston 56 causes the slidingsleeve 58 to slide, thereby causing the ramp surfaces 40 to move under and along the interior surfaces 42 of thecutter blades 34. Thecutter blades 34 are thus pivoted outwardly thereby moving the cuttingtips 52 radially outward to a cutting position. It will be understood based upon the present disclosure that a conventional actuating device for selectively directing fluidic material in a down hole tool may be used as an alternative to the illustratedactivation device 76. It will also be understood that a conventional device for otherwise selectively actuating thecutter blades 34 to expand may also be used as an alternative to theactuator 50 without departing form certain aspects of the invention. - With reference also to
FIGS. 4 and 5 , thecutter tool 10 with radially expandedcutter blades 34 is moved axially upward toward atransition area 90 between thelower casing section 20 and theextra casing portion 24. Thecutter tool 10 is also rotated within thecasing 14. Rotational force is transmitted to thecutter blades 34 and the cuttingtips 52 engage with thetransition area 90 between the expandedlower casing portion 20 and unexpandedextra casing portion 24. - In
FIG. 6 , thelower casing 20 is completely severed from theextra portion 24. Theextra portion 24 is supported by the radially expandedtips 52 of thecutter blades 34 and is lifted up and removed from the wellbore. -
FIG. 7 shows an embodiment of thecutter tool 10 activated by aclosing dart 76B to retract thecutter blades 34 to a non-cutting position. In situations where thecutter tool 10 needs to be withdrawn from thewellbore casing 14, after it was previously actuated to the cutting position, theopening dart 76A can be blown out with increased fluid pressure and aclosing dart 76B can be injected to seat at seat 82. Theclosing dart 76B provides arelief passage 92 axially aligned with the openingport 68 andannulus 84 to permit escape of fluidic material from the openingchamber 62 so that pressure therein is reduced. Also, aclosing passage 94 is aligned with the closingport 72 andannulus 88 to providefluidic material 78 into the closingchamber 64 so that pressure therein is increased. Theclosing piston 66 is thus actuated by the differential pressure to move the slidingsleeve 58 to retract thecone 44 and thereby allow thecutter blades 34 to retract radially inward to a non-cutting position. -
FIG. 8 shows a cross-section through an exemplary embodiment of theexpander device 36 withcutter blades 34 in the expanded condition. Theinterior surface 42 of thecutter blades 34 are supported byramp surfaces 40 oflower cam arms 44 a of theexpander cone 44.Dummy blades 37 are interleaved with thecutter blades 34 and supported on aupper expander cone 96 withupper cam arms 98. The cutter blades are pivoted, atpivot point 38, outwardly so that cuttingtips 52 are at a diameter for cutting the extra casing section 24 (not shown inFIG. 8 ) as described above. Rotational force is transmitted to theexpander device 36 with torsionalforce transmitter device 46, shown as messing teeth 46 a formed at an upper end ofupper expander cone 44. The rotation is transferred down the tool to the actuator and slidingsleeve 58 and to any other devices connected below, through another torsionalforce transmitter device 98 as with meshingteeth 98 a. - Thus what has been disclosed in the several exemplary embodiments is a cutter tool for a wellbore casing including a rotatable tubular support, at least one cutter blade supported on the rotatable tubular support, the cutter blade having a retracted position for insertion into the wellbore casing and an expanded position for cutting engagement with the wellbore casing and an actuator for moving the cutter blade from the retracted position to the expanded position for cutting engagement with the wellbore casing.
