Definitions

  • This disclosure relates to methods and apparatus for use in creation of boreholes for accessing subsurface formations.
  • the disclosure has particular application in operations where formations are subject to hydraulic fracturing.
  • fissures In the oil and gas exploration and production industry bores are drilled from surface to access subsurface hydrocarbon-bearing rock formations. In certain formations, production of hydrocarbons may be enhanced by fracturing the rock to create fissures through which fluids may pass. These fissures may be created by a number of techniques, one being hydraulic fracturing, often referred to a tracking. In this technique, high pressure fluid is injected into the formation to fracture the rock.
  • the fluid may take any appropriate form, and may comprise acid and may carry material, known a proppant, which lodges in the fissure and maintains the fissures open when the fluid pressure is reduced.
  • a drilled bore may comprise a vertical or near vertical portion which leads into a substantially horizontal portion extending through the hydrocarbon-bearing formation.
  • the far or distal end of the horizontal portion may be referred to as the toe of the well, while the end of the horizontal portion adjacent the vertical portion may be referred to as the heel of the well.
  • the process is normally carried out in stages, starting at the toe and working along the well to the heel. Given that high fluid pressures are employed during the fracturing operations, and the well bore is open to the formation during the fracturing operations, operators exercise great care in ensuring that the well remains fluid-tight and the well pressure is closely monitored and controlled.
  • the fracturing operation may involve a suitable bottom hole assembly (BHA) mounted on a tubular support member which extends from surface. At or near surface, the support member may extend through a pressure containment apparatus such as a blowout preventer (BOP).
  • BHA bottom hole assembly
  • BOP blowout preventer
  • the apparatus may provide a number of different sealing mechanisms to engage the outside of the support member and safely contain the well pressure.
  • the high pressures utilised in fracturing operations may also result in the creation of forces which tend to push the support member out of the bore.
  • it is necessary to translate the support member through the various seals to locate the BHA at the appropriate location in the bore and this often requires manipulation of the surface sealing arrangement and may require the provision of apparatus to accommodate the pressure forces acting on the support. Accommodating these different requirements inevitably incurs significant time and expense.

  • the sleeves 28 are initially closed.
  • the liner 26 has been hung off a 10 3 ⁇ 4 inch (27.31 cm) diameter liner 30, which has itself been hung off a 14 inch (35.56cm) diameter casing 32.

  • the 14 inch (35.56cm) casing 32 sits within a 10 3 ⁇ 4 inch (27.31 cm) diameter tie-back casing 34 and a 20 inch (50.8cm) diameter conductor 36.
  • the 5 1/2 inch (13.97cm) liner 26 is cemented in the bore section 24; that is the annulus 38 between the liner 26 and the wall of the horizontal section 24 is filled with cement slurry 40.
  • cement slurry 40 Once the cement 40 has set, as illustrated in Figure 3, the liner 26 is pressure tested. If considered necessary by the operator a cleanout string 42 is then run into the cemented liner 26 and a cleaning operation carried out to remove cement residue from within the liner 26, as illustrated in Figure 4. This may involve the use of brushes and reverse circulation of cleaning fluid 44. Next, the cleaning fluid 44 is displaced from the well by clean kill weight brine 46, as illustrated in Figure 5.
  • the brine 46 has a density selected to produce a hydrostatic pressure in the liner 26 sufficient to prevent flow of hydrocarbons from the formation 22 into the well 10, although in other examples an operator may choose to use lighter fluid and may even have the well underbalanced.
  • the cleanout string 42 is then pulled out of hole, as illustrated in Figure 6.
  • the well 10 is now ready for fracturing and a fluid delivery tool, such as a fracturing bottom hole assembly (frac BHA) 50 is run into the well 10 on a work string 52, as illustrated in Figure 7.
  • frac BHA 50 may take any appropriate form, and an example of suitable frac BHA 50, and an example of a sleeve 28, is illustrated in Figures 7a to 7c of the drawings.
  • Figures 7a to 7c illustrate a sleeve 28 comprising a barrel 176 located in a recess provided in the wall of the sleeve body 166.
  • Figure 7a illustrates the sleeve 28 in a closed configuration, in which the barrel 176 and seals 100 isolate ports 174 in the sleeve body 166.
  • the barrel 176 is axially movable relative to the body 166 to expose the ports 174.
  • this has been achieved by locating the frac BHA 50 within the barrel 176 and activating slips 158 and a packer element 160 to engage the barrel 176 and applying an axial mechanical and pressure force to translate the barrel 176 downwards.
  • fracturing fluid 194 may be pumped through the ports 174 and into the surrounding formation. Thereafter the barrel 176 may be moved, by pulling the frac BHA 50 upwards, to close the ports 174.
  • the barrel 176 When it is subsequently desired to produce from the surrounding formation the barrel 176 may be moved to an intermediate position in which a ported section of the barrel 176 extends across the ports 174, as illustrated in Figure 7c.
  • the ported section of the sleeve is provided with a proppant restrictor 102 defining apertures 104 which are dimensioned according to the size of the proppant particles present in the fracturing fluid 194. In particular, it is desired to prevent proppant particles from flowing back into the well.
  • the proppant supplied during the latter stages of a tracking operation may be coated with resin, which resin tends to make the proppant "sticky" and be held in the formation, or bind with other proppant particles.
  • the properties of the resin may create other issues, and present the operator with environmental and safe handling complications.
  • the openings 104 may be sized to have a diameter a selected multiple of the diameter of the average proppant particle. If the screen openings are smaller there is an increased likelihood that the openings will be blocked by the particles, and of the openings are larger there is an increased likelihood that the particles will pass through the openings with the produced fluid, this creating operational difficulties for the operator. Further, the openings 104 and the ports 174 are provided with bevelled edges 106, as illustrated in Figure 7d. There is a tendency for proppant particles to aggregate at the ports 174 and the openings 104. This provides a degree of filtering or screening, but also restricts flow through the ports 174 and openings 104.
  • the beneficial effects of this aggregation may be maximised if the proppant particles can be encouraged to aggregate in an arcuate form, bridging rather than filling the ports 174 and openings 104.
  • the provision of the bevelled edges 106 promotes the creation of arcs of proppant particles 108.
  • the work string 52 has a diameter of 3 1 ⁇ 2 inches (8.89cm) and is mounted on 5 1 ⁇ 2 inch (13.97cm) diameter drill pipe 80.
  • the work string 52 and drill pipe 80 are formed from multiple sections of pipe joined by threaded end connections. As such the strings 52, 80 are physically robust and are well suited to pushing the BHA 50 through a long horizontal bore section.
  • the strings 52, 80 also provide a relatively large internal bore for delivery of large volumes of fracturing fluid at high pressure, as will be described.
  • a seal is provided at the proximal end of the vertical well section 18, at the BOP 16.
  • the drill pipe 80 passes through the BOP 16 which, in the illustrated example, is located on the seabed.
  • the BOP 16 will typically include a number of seal arrangements for engaging the outer surface of the drill pipe 80, for example an annular preventer 82 and rams 84.
  • the annular preventer 82 will typically include a sealing element in the form of a large elastomeric doughnut that is mechanically squeezed inward to seal on the drill pipe 80.
  • the rams 84 typically include two halves of a cover for the well that are split down the middle and define a cut-out that corresponds to the diameter of the drill pipe 80. Hydraulic rams may be operated to force the two halves of the cover together to seal the wellbore when the drill pipe 80 extends into the well 10.
  • one of the annular preventer 82 and rams 84 is closed around the drill pipe 80 to provide an upper seal.
  • Surface pumps 86 are then operated to pressurise the fluid in the well 10 to a desired level and further weight is applied to the drill pipe 80.
  • the combination of pressure and weight generate an axial force on the BHA 50 sufficient to open the ports 174, as described above with reference to Figure 7b.
  • the drill pipe 80 moves down through the actuated BOP seal, for example through the annular preventer 82, which maintains a sealing contact with the drill pipe surface; this is sometimes referred to as "stripping in”.
  • a predetermined volume of fracturing fluid 94 is then pumped down the drill pipe 80 and work string 52, through the ports 174 and the fissures 92 in the cement 40 and into the formation 22, as illustrated in Figure 8.
  • the fracturing fluid 94 is followed by a volume of kill weight brine 96, the volume of brine 96 pumped into the well being selected to under-displace the fracturing fluid 94 by a predetermined volume, for example 3 bbl (477 litres), as illustrated in Figure 9.
  • the brine 96 is pumped into the well until only 3 bbl (477 litres) of fracturing fluid 94 is calculated to remain within the work string 52.
  • 3 bbl 477 litres
  • the sleeve 28a is then closed by pulling up on the drill string 80 and work string 52, through the still-closed BOP annular preventer 82.
  • the corresponding movement of the BHA 50 will pull the barrel 176 back through the sleeve body 166 to close the ports 174.
  • the well 10 is only open to the formation 22 for a relatively short period while the ports 174 are open. Movement of the drill string 80 during this period is achieved by stripping in and out through the annular preventer 82. Accordingly, there is no requirement for the operator to manage well pressure, which greatly simplifies operations and allows most operations to be carried out far more quickly than would be the case if it was necessary to continually manage well pressure.
  • the well 10 is then reverse circulated clean, as illustrated in Figure 10, with clean kill weight brine 46; the brine 46 is pumped down from surface through the annulus 97 around the drill pipe 80 and work string 52 and then passes into the work string 52 and travels to surface through the work string 52 and drill pipe 80, carrying any remaining fracturing fluid 94 to surface. The circulation of brine 46 may continue until the returns at surface are clean.
  • the annular preventer 82 may be opened once the ports 174 have been closed.
  • the drill pipe 80 and work string 52 are then pulled back to locate the frac BHA 50 in the second sleeve 28b, as illustrated in Figure 1 1 .
  • the process as described above is then repeated to: strip in the string 80 in through the annular preventer 82 in the BOP 16 and open the sleeve 28b; pump fracturing fluid 94 through the open sleeve 28b into the formation 22 surrounding the sleeve 28b ( Figure 12); under-displace the fracturing fluid 94 with kill weigh brine 46; strip out the strings 80, 52 to close the sleeve 28b (Figure 13); and then reverse circulate with clean kill weight brine 46 to clean the well 10 ( Figure 14).
  • the hydraulic fracturing operation as described above will typically be accomplished in a single run, without having to retrieve the BHA 50 to surface. There is also a significant time saving due to the limited time that the sleeves 28 are open and providing fluid communication with the formation 22; during most of this time the surface pumps 86 are operating and pumping high pressure into the formation 22, and the sleeves 28 are closed immediately after the pumps 86 are switched off. As a result there is little or no need to manage well pressure. If desired the drill pipe 80 and work string 52 may then be then be pulled out of hole (POOH).
  • the well has now been tracked and is ready to receive production tubing.
  • some or all of the sleeves 28 may be opened. If considered necessary or desirable one or more of the sleeves 28 may be subsequently closed if, for example, a relatively large water fraction is being produced through the sleeve 28.
