Definitions

  • the present invention relates to an apparatus and method for drilling an extended reach well in a formation.
  • ERD extended reach drilling
  • An ERD well is generally defined as a well with a throw ratio of approximately 2:1 where the throw ratio is the ratio of horizontal depth to true vertical depth (TVD).
  • Some extended reach wells characterized as ultra ERD wells may have throw ratios as high as 6:1.
  • a drill string or drill pipe
  • a drill bit attached to the lower end
  • drilling mud is circulated ⁇ through the annular space between the drill string and the wellbore wall to cool the bit and transport cuttings (rock chips from drilling) to the surface.
  • the drill string and bit are removed and the wellbore is lined with a string of steel pipe known as casing.
  • the casing serves to stabilize the newly formed wellbore and facilitate the isolation of certain areas of the wellbore adjacent to the hydrocarbon bearing formations.
  • drilling with casing To reduce costs and drilling time, a process known as "drilling with casing" is often employed. This process involves attaching the drill bit to the same string of tubulars that will be used to line the wellbore. Because the same string is used, both phases of the wellbore formation can be completed in a single trip.
  • the traditional nested arrangement of casing in a well causes the available diameter for the production of hydrocarbon fluid to decrease with depth in a stepwise fashion. This becomes a technical and economic problem for deep wells with many separate casings because drilling a small diameter deep hole becomes very challenging.
  • the oil and gas industry has begun to experiment with new drilling and casing techniques that involve radially expanding individual casing strings as they are installed in the well in order to maximize the available diameter.
  • coiled tubing is a single strand of flexible pipe that is capable of handling a drilling assembly.
  • a downhole drilling motor is used to create the mechanical energy necessary to rotate the drill bit and a tractor device that grips onto the interior of the wellbore maintains the proper amount of weight on bit and holds the reactive torque from the motor.
  • US-A-6,467,557 Bl discloses a means to overcome the challenges associated with extended reach drilling using a rotary long reach drilling assembly.
  • the tool described comprises an elongated conduit extending through a bore, a drill bit for being rotated to drill the bore, a 3D steering tool on the conduit for steering the bit, and a tractor on the conduit for applying force to the bit.
  • the tractor includes a gripper which can assume a first position that engages an inner surface of the bore and limits movement of the gripper relative to the inner surface.
  • the gripper can also assume a second position that permits substantially free relative movement between the gripper and the inner surface of the bore.
  • a propulsion assembly moves the tractor with respect to the gripper while the gripper position is in the first position.
  • WO99/09290 discloses an extended reach drilling system for drilling a borehole in an underground formation.
  • the ERD system comprises a drill bit, a motor for driving the drill bit, a drill-pipe to surface, a hydraulic cylinder/piston arrangement for providing the required weight on bit, the drill-pipe being coupled to a selected one of the cylinder and the piston of said cylinder/piston arrangement by swivel means allowing rotation of the drill pipe relative to one of the cylinder or the piston, the drill bit being coupled to the other one of the cylinder and the piston, and locking means for locking said selected one of the cylinder and the piston against the borehole wall, the locking means being operable between an engaged and a disengaged position.
  • WO97/08418 discloses a method and apparatus for propelling a tool having a body through a passage.
  • the tool includes a gripper including at least a gripper portion, which can assume a first position that engages an inner surface of the passage and limits relative movement of the gripper portion relative to the inner surface.
  • the gripper portion can also assume a second position that permits substantially free relative movement between the gripper portion and the inner surface of the passage.
  • the tool includes a propulsion assembly for selectively continuously moving the body of the tool with respect to the gripper portion while the gripper portion is in the first position.
  • the present inventions include a method for drilling a well in a formation comprising inserting a thruster, a first conduit, and a drill bit into a wellbore lined with a previous casing and applying a force to the first conduit with the thruster wherein the thruster grips onto the previous casing.
  • the present inventions include an apparatus for drilling a well in a formation through a wellbore lined with a previous casing comprising a drilling assembly and a thruster connectable to the drilling assembly; wherein the thruster is capable of gripping onto the previous casing and providing a force to the drilling assembly.
  • the present inventions include a method for drilling a well in a formation comprising providing a wellbore lined with a previous casing, inserting a first drilling assembly comprising a drill bit at a distal end, a first conduit connectable to the drill bit, and a thruster connectable to first conduit, gripping the previous casing with the thruster, and drilling a well.
  • Figure 1 illustrates a side view of an extended/ultra extended reach drilling apparatus and method.
  • Figure 2 illustrates a side view of another embodiment of the extended reach drilling apparatus and method. Detailed Description
  • first conduit 104 is a section of drilling casing; however, other similar oilfield equipment (e.g. liner) could be used.
  • Thruster 106 is shown in this embodiment as a tractor. Any substitute device capable of gripping or applying force could be used.
  • the drilling assembly (comprising first conduit 104, drill bit 105, and thruster 106) is inserted into wellbore 101.
  • drill pipe 107 is used to perform this function; however, other oilfield equipment (e.g. coiled tubing) may be used instead.
  • thruster 106 applies a force to first conduit 104 causing drill bit 105 to drill a hole and extend wellbore 101.
  • Thruster 106 provides the necessary weight on bit for penetration by gripping onto previous casing 103.
  • the torque required to rotate drill bit 105 may be transferred by first conduit 104.
  • first conduit 104 may also be drilling casing or other oilfield equipment. It is also possible to insert a drill pipe inside the liner to transmit the torque to drill bit 105.
  • first conduit 104 is removed from the drilling assembly and hung against previous casing 103.
  • First conduit 104 is optionally secured in place by expansion, cementing, or any other method.
  • Drill pipe 107 is then used to remove the drilling assembly.
  • a new drilling assembly is lowered into wellbore 101 comprising drill bit 105, thruster 106, and second conduit (not shown). The steps are then repeated until the desired depth is reached.
  • Drilling assembly 204 is being lowered into wellbore 201. Thruster 205 and liner 206 are also shown being lowered into wellbore 201. In the embodiment shown, coiled tubing 207 is used to perform this function; however, other oilfield equipment (e.g. drill pipe) may be used instead of coiled tubing.

  • drilling casing 206 is removed from the drilling assembly and hung against previous casing 203. Drilling casing 206 is then expanded using expander 212.
  • drilling casing 206 may be expanded against formation 202.
  • Drilling casing 206 may also be expanded to be the same diameter as previous casing 203; it may also be expanded so that it has a smaller diameter.
  • drilling casing 206 is expanded so that its outer diameter is substantially equal to the inner diameter of previous casing 203.
  • Expander 212 may be a pig, cone, rotary expansion device, cyclic expansion device or any other expansion device.
  • drilling casing 206 is then optionally cemented in place.
  • a new drilling assembly is lowered into wellbore 201 the steps are then repeated until the desired depth is reached.
  • the subsequent drilling casings may each be expanded so that the wellbore is monodiameter.
