Definitions
- the present invention relates to methods and apparatus for forming a lateral wellbore in a well, more particularly the invention relates to the formation of lateral wellbores with greater efficiency and with fewer trips into the wellbore.
- Lateral wellbores from a central cased wellbore is well known in the art.
- Lateral wellbores are typically formed to access an oil bearing formation adjacent the existing wellbore; to provide a perforated production zone at a desired level; to provide cement bonding between a small diameter casing and the adjacent formation; or to remove a loose joint of surface pipe.
- Lateral wellbores are advantageous because they allow an adjacent area of the formation to be accessed without the drilling of a separate wellbore from the surface.
- Any number of lateral wellbores may be formed in a well depending upon the needs and goals of the operator and the lateral wellbores can be lined with tubular like the main wellbore of the well from which they are formed.
- the most well known method of forming a lateral wellbore uses a diverter or whipstock which is inserted into the main wellbore and fixed therein.
- the whipstock includes a concave, slanted portion which forms a surface for gradually directing a cutting device from the main wellbore of the well towards the wall of the wellbore where the lateral wellbore will be formed.
- the cutter is fixed at the end of a string of rotating pipe. Thereafter, an opening or “window" is formed in the wellbore casing as the cutter is guided through the wall by the whipstock.
- Forming a lateral wellbore with a whipstock assembly typically proceeds as follows: a whipstock assembly including an anchor portion therebelow is lowered into the well to the area below the point where the window is to be formed. The assembly is then fixed in the well with the anchor securely held within the wellbore casing. A drill string with a cutting tool disposed at the end thereof is then lowered into the well and the drill string and cutter are rotated in order to form the window in the wellbore.
- the drill string and cutter can be installed in the well at the same time as the whipstock assembly by attaching the two with a shearable mechanical connection between the whipstock and the cutter. Thereafter, the cutter and drill string are removed from the well and the cutter is replaced with a drill bit. The drill string and drill bit are then lowered once more into the wellbore and the lateral wellbore is drilled using the conventional drill bit. After the lateral wellbore is formed, it is typically lined with its own casing which is subsequently cemented in place.
- the formation of a lateral wellbore requires several separate pieces of equipment and more importantly, requires several trips into the well to either install or remove the downhole apparatus used to form the window or the lateral wellbore.
- a mill/drill is a special bit specifically designed to both mill through a casing and drill into a formation.
- Use of a mill/drill can eliminate the use of a separate mill and drill bit in a lateral wellbore operation and therefore eliminate the need to pull the mill out of the wellbore after forming the window in order to install the drill bit to form the lateral wellbore.
- the mill/drill includes materials of different physical characteristics designed to cut either the metallic material of the well bore casing to form a window or designed to cut rock in formation material as the lateral wellbore is formed.
- inserts are installed in the drill bit whereby one set of inserts includes a durable cutting structure such as tungsten carbide for contacting and forming the window in the wellbore casing and a second set of inserts is formed of a harder material better suited for drilling through a subterranean formation, especially a rock formation.
- the first cutting structure is positioned outwardly relative to the second cutting structure so that the first cutting structure will mill through the metal casing while shielding the second cutting structure from contact with the casing.
- the first cutting structure can wear away while milling through the casing and upon initial contact with the rock formation, thereby exposing the second cutting structure to contact the rock formation.
- Combination milling and drill bits such as the foregoing are described in U.S. Patent Nos. 5,979,571 and 5,887,668 .
- a drill bit is disposed at the end of a tubular that is of a sufficient diameter to line the wall of the borehole being formed by the drill at the end thereof. Once the borehole has been formed and the liner is ready to be cemented in the borehole, the drill bit at the end thereof is either removed or simply destroyed by the drilling of a subsequent, smaller diameter borehole.
- Drilling with liner can typically be performed two ways: In the first method, the liner string itself with the drill bit fixed at the end thereof rotates. In a second method, the liner string is non-rotating and the drill bit, disposed at the end of the liner string and rotationally independent thereof, is rotated by a downhole motor or by another smaller diameter drill stem disposed within the liner that extends back and is rotated from the surface.
- the bit includes radially extendable and retractable arms which extend outwards to a diameter greater than the tubular during drilling but are retractable through the inside diameter of the tubular whereby, when the wellbore is completed, the bit can be completely removed from the wellbore using a wireline device. The foregoing arrangement is described in U.S. Patent No. 5,271,472 .
- a non-rotating tubular is used with a two-part bit having a portion rotating within the end of the tubular and another portion rotating around the outer diameter of the tubular.
- the rotation of each portion of the bit is made possible either by a downhole motor or by rotational force supplied to a separate drill stem from the surface of the well. In either case, the central portion of the bit can be removed after the wellbore has been formed.
- the liner remains in the wellbore to be cemented therein.
- Yet another emerging technology offering savings of time and expense in drilling and creating wellbores relates to rotary steerable drilling systems. These systems allow the direction of a wellbore to be changed in a predetermined manner as the wellbore is being formed.
- a downhole motor having a joint within the motor housing can create a slight deviation in the direction of the wellbore as it is being drilled.
- Fluid-powered motors have been in use in drilling assemblies in the past.
- Another means of directional drilling includes the use of rotary steerable drilling units with hydraulically operated pads formed on the exterior of a housing near the drill bit.
- the mechanism relies upon a MWD device (measuring while drilling) to sense gravity and use the magnetic fields of the earth.
- the pads are able to extend axially to provide a bias against the wall of a borehole or wellbore and thereby influence the direction of the drilling bit therebelow.
- Rotary steerable drilling is described in U.S. Patent Nos. 5,553,679 , 5,706,905 and 5,520,255 .
- Technology also exists for the expansion of tubulars in a wellbore whereby a tubular of a first diameter may be inserted into a wellbore and later expanded to a greater inside and outside diameter by an expansion tool run into the wellbore on a run-in string.
- the expansion tool is typically hydraulically powered and exerts a force on the inner surface of the tubular when actuated.
- FIGS 1 and 2 are perspective views of the expansion tool 100 and Figure 3 is an exploded view thereof.
- the expansion tool 100 has a body 102 which is hollow and generally tubular with connectors 104 and 106 for connection to other components (not shown) of a downhole assembly.
- the connectors 104 and 106 are of a reduced diameter (compared to the outside diameter of the longitudinally central body part 108 of the tool 100), and together with three longitudinal flutes 110 on the central body part 108, allow the passage of fluids between the outside of the tool 100 and the interior of a tubular therearound (not shown).
- the central body part 108 has three lands 112 defined between the three flutes 110, each land 112 being formed with a respective recess 114 to hold a respective roller 116.
- Each of the recesses 114 has parallel sides and extends radially from the radially perforated tubular core 115 of the tool 100 to the exterior of the respective land 112.
- Each of the mutually identical rollers 116 is near-cylindrical and slightly barrelled.
- Each of the rollers 116 is mounted by means of a bearing 118 at each end of the respective roller for rotation about a respective rotational axis which is parallel to the longitudinal axis of the tool 100 and radially offset therefrom at 120-degree mutual circumferential separations around the central body 108.
- the bearings 118 are formed as integral end members of radially slidable pistons 120, one piston 120 being slidably sealed within each radially extended recess 114.
- each piston 120 ( Figure 3 ) is exposed to the pressure of fluid within the hollow core of the tool 100 by way of the radial perforations in the tubular core 115.
- the expander tool is designed to be inserted in a tubular string. It can however, also be used at the end of a tubular string with fluid passing through it via ports formed in its lower end.
- the expansion tool can be deactivated and removed from the wellbore.
- Methods for expanding tubulars in a wellbore are described and claimed in Publication No. WO 00/37766 .
- WO 99/06670 describes a method for creating a zonal isolation by inserting an expandable tubular through existing well casing into an uncased section such as a lateral branch. One end of the expandable tubular is pressed towards the wall of the uncased section of well and the other end is pressed against the inner surface of the well casing.
- US 5,887,668 describes a combination tool which can be used for milling and drilling.
- a method of expanding a liner extending into a lateral wellbore through a window in casing disposed in a wellbore comprising:
- Figure 4A is a section view of a cased wellbore 10 having a liner 15 disposed therein and a mill/drill 20 disposed at the end thereof.
- a shearable connection 25 between the mill/drill and a diverter, in this case a whipstock 30, therebelow allows the entire assembly, including an anchor 35, to be run into the wellbore at once.
- the anchor 35 is located below the whipstock and fixes the whipstock in place allowing the mill/drill 20 to form a window at a predetermined point in the wall of the casing 40 as it rotates along a concave portion 42 of the whipstock 30.
- the mill/drill 20 is rotationally fixed to the end of the liner 15 and rotational force is applied to the liner at the well surface.
- Figure 4B is a section view of the wellbore illustrating a window 45 that has been formed in the casing wall 40 by the rotating mill/drill 20.
- Figure 4B also illustrates the liner 15 having advanced through the window 45 and into the lateral wellbore.
- Figure 4C a section view of the wellbore 10, shows the lateral wellbore 50 formed and lined with the liner 15 which was inserted into the lateral wellbore as it was formed.
- the mill/drill 20 remains at the end of the liner 15 after the lateral wellbore 50 is formed and can be subsequently destroyed by additional drilling.
- portions of the liner extending into the central wellbore from the window may be removed. Techniques for cutting off that portion of a liner extending into and blocking a vertical wellbore are described in U.S. Patent Nos. 5,301,760 and 5,322,127 .
- the liner 15 with the mill/drill disposed thereupon can be non-rotating and a two-piece drill/mill 55 rotates independently of the liner 15 with rotational forces supplied by a downhole motor within the liner or by a rotational device located at the surface of the well.
- Figure 5A is a section view of a two-piece mill/drill 55 with rotational force provided thereto by a downhole motor 60
- Figure 5B is a view of the two-piece mill/drill 55 with rotational force provided from the well surface (not shown).
- a first portion 65 of the two-piece mill/drill 55 has an outer diameter smaller than the inside diameter of the liner and a second portion 70 of the mill/drill 55 extends around the perimeter of the liner and is rotationably coupled to the first portion 65.
- the portions 65, 70 of the mill/drill 55 can be disconnected from each other and the first portion 65 may be removed from the lateral wellbore with a wireline or any other well-known technique for recovering downhole devices from a wellbore.
- undersized liner When drilling a lateral wellbore with liner, undersized liner may be used during the formation of the lateral wellbore to facilitate the operation and thereafter, when the wellbore is formed, the liner can be expanded to increase its diameter to more closely match the inside diameter of the lateral wellbore. Enlargement of the liner is typically accomplished by insertion of a selective expansion device into the lateral wellbore and subsequent actuation of the device which places an outward force on the wall of the liner. Moving the actuated device axially in the liner creates a section of enlarged liner.
- Figure 6A is a section view of a lateral wellbore 10 drilled with liner 300 and having a selective expansion tool 310 inserted therein on a separate tubular string 312 for enlarging the diameter of the liner.
- the selective expansion tool 310 is run into the lateral wellbore where it is then actuated and urged towards the window 315 of the wellbore, enlarging the liner to a size adequate to line the lateral wellbore for cementing therein.
- Compliant rollers 116 ( Figure 1 ) of the expansion tool 310 may alternatively be cone-shaped to facilitate a gradual enlargement of the liner as the expansion tool moves therethrough.
- FIG 6B another section view of a lateral wellbore 10, the undersized liner 312 has been expanded up to and through the window in the vertical casing in a manner that has sealed an annular area 320 between the exterior of the liner and the window opening. After removal of the selective expansion tool 310, the liner 312 can be severed at the window leaving a sealed lateral wellbore extending from the central wellbore.
- Figure 7A is a section view of a wellbore 10 having a conventional drill stem 75 for providing rotational force to a mill/drill 78 disposed at the end thereof.
- a rotary steerable mechanism 80 is installed above the mill/drill and includes selectively radially extendable pads 85 which can transmit a force against the casing wall causing the mill/drill therebelow to be diverted towards the opposite wall of the casing.
- a measurement while drilling device (MWD) 90 is installed within the tubular string to provide orientation.
- the assembly including the MWD 90, steerable mechanism 80 and mill/drill 78 is run into the wellbore 10 to a predetermined depth and, thereafter, at least one pad 85 of the rotary steerable mechanism 80 is actuated to urge the mill/drill 78 against that area of the casing wall 87 where the window will be formed.
- the assembly extends into the window and the lateral wellbore is formed.
- the assembly is removed from the well and the new lateral wellbore may be lined with tubular liner in a conventional manner well known in the art.
- Figure 8 is a section view of a wellbore 10 wherein a liner 100 is provided with a two-piece mill/drill 105 disposed at the end thereof, the liner having a bent portion 115 at the lower end which directs the mill/drill 105 to a predetermined area of the wellbore casing 120 where a window will be formed.
- the liner is non-rotating and the mill/drill 105 rotates independently thereof, powered by either a downhole motor 110 thereabove or a rotary unit located at the surface of the well (not shown).
- downhole motor 110 may have a bent housing.
- the mill/drill is a two-piece assembly with a centre portion 107 that can be removed when the formation of the lateral wellbore is complete.
- a non-rotating straight liner 200 is provided with a rotary steerable mechanism 205 and a mill/drill 210 disposed at a lower end thereof.
- the mill/drill 210 rotates independently of the non-rotating liner and is powered either with a downhole motor disposed within the liner in a separate string or a rotating unit at the surface of the well.
- the rotary steerable mechanism 205 like those described herein has selectively extendable pads 207 which exert a force against the casing wall 120, of the central wellbore, biasing the mill/drill 210 therebelow in a direction where the window is to be formed in the casing wall and formation of the lateral wellbore is to begin.
- the assembly is lowered into the well to a predetermined depth and thereafter, the 200 liner and mill/drill 210 rotate as the mill/drill 210 is urged against the wall of the casing 220 biased by the rotary steerable mechanism 207.
- the mill/drill 210 forms a window in the casing and then the assembly, including the rotating liner 200, is urged through the window and the lateral wellbore is formed.
- an MWD device (not shown) which is located on a separate tubular string within the liner is removed and the fixed mill/drill is left in the lateral wellbore.
