Definitions

  • the invention concerns a device and method for centralizing a tubular in a bore, as set out by the preambles of claims 1 , 8 and 11.
  • the invention is particularly useful in centralizing a casing, in connection with plugging-and-abandonment operations in subterranean hydrocarbon wells.
  • Hydrocarbons e.g. oil and/or gas
  • Hydrocarbons are extracted from subterranean formations, often referred to as a reservoirs, by drilling a wellbore into the formations containing hydrocarbons.
  • a completion normally involves the design, selection, and installation of equipment and materials in or around the wellbore for conveying, pumping, or controlling the production or injection of fluids.
  • production testing of the well can begin.
  • Hydrocarbon wells normally have an upper and outer conductor, which forms the base of the well, an upper casing arranged into and in extension of the conductor, and further down in the well more casings which are arranged into and overlaps the above casing.
  • a production tubing string is subsequently loca ted in the middle of the well for transporting petroleum from the bottom of the well to the earths surface or to a seabed facility. Annuli are thus formed between the different casings, as well as between the outer casing and the wellbore wall (i.e. the formation) .
  • cement plugs are normally used to provide a barrier in the well .
  • a common procedure during plug-and-abandonment operations is to place a cement plug inside an inner casing string and a further plug in the annulus between the inner casing string and the outer casing string, and in the annulus between the outer casing and the formation. The plug will then extend across the full section of the well, and extend a predetermined axial distance.
  • One commonly used method to install such plug is to make holes in the casing wall and force cement from within the central casing, through the casing wall holes and into the annulus. This procedure, and various variants, are well known in the art.
  • - wall-abutment means configured for generating a force between the tubular and the bore in order to at least partly shift the tubular inside the bore.
  • each penetration tool comprises sensing means configured for sensing the distance travelled by the penetration tool.
  • Each penetration tool may comprise sensing means configured for sensing the distance to a wall of the bore.
  • the penetration tools may be releasably connected to the motive means.
  • Three penetration tools may be arranged at 120° intervals around the body circumference.
  • Four penetration tools may be arranged at 90° intervals around the body circumference.
  • Five or more penetration tools may be arranged at regular intervals around the body circumference.
  • the penetration tool may comprise a milling tool.
  • the tool may which impinges on the wall may be extended further, whereby the casing is moved as a reaction.
  • the device body may be subsequently be disconnected from the tools and retrieved out of the bore upon completion of the steps.
  • Figure 1 is a cross-sectional drawing of an embodiment of the invented device, in an unactuated state, placed in a casing in a formation wellbore;
  • Figure 2 corresponds to figure 1 , and shows the invented device in an activated state, with four tools having been extended through the casing wall;
  • Figure 3 corresponds to figure 2, and shows how the tools have shifted the casing in the wellbore, to a more centralized position in the wellbore than previously;
  • Figure 4 corresponds to figure 4, and shows that the invented device has been removed from the casing, while the tools remain in the casing wall;
  • Figure 5 is a schematic illustration of a tool in an extended position
  • Figure 6 is a schematic illustration of an alternative embodiment of a tool
  • Figure 7 is a schematic illustration of an alternative embodiment of the invented device, during a first milling operation
  • Figure 8 illustrates the device of figure 7, during the installation of a first set of wedges in an annulus between a casing and a formation
  • Figure 9 illustrates the device of figure 7, during a second milling operation
  • Figure 10 illustrates the device of figure 7, during the installation of a second set of wedges in an annulus between a casing and a formation; and Figure 11 shows the first and second sets of wedges installed in an annulus between a casing and a formation, and a cement plug having been placed in a section of the annulus and casing.
  • Figure 1 shows a casing 1 placed in a wellbore 2 having a wall 2a against a subterranean formation 7.
  • the formation wall 2 a may be of an irregular shape and contain cracks, fissures and unconsolidated regions.
  • the casing 1 is not properly centralized in the wellbore 2, but is in contact with a portion of the wellbore wall 2a (in the upper, left-hand part, as shown in figure 1). There is thus no complete annulus between the casing and the wellbore wall 2a, or the annulus 3 is insufficiently wide, therefore rendering a cementing procedure impossible at this location.
  • Figure 1 also shows the invented device 4 in place inside the casing 1.
  • the device 4 may be connected to a drillpipe, coiled tubing (not shown), or other known downhole device conveyance means, and powered and controlled from an uphole location, in a manner generally known in the art.
  • the device 4 comprises a body 9 and four individually operated tools 5, which will be described below.
  • each individual tool 5 has been extended from the tool body 9 and advanced towards and through the casing wall.
  • Each individual tool 5 is extended by individual arms 6, which may be hydraulically operated telescopic cylinders, known per se in the art.
  • Each tool 5 comprises casing penetration means (not shown) for making a hole or other opening in the casing wall. Such casing penetration means may for example be jet blasting nozzles or a milling tool, all of which are generally known in the art.
  • Each tool 5 also comprises attachment means (not shown in figure 2) for attaching the tool to the casing wall, for example dogs, slips, or other anchoring means generally known in the art.
  • a first tool portion 5a of the tool 5 may be held in position in the hole made in the casing wall, while a second tool portion 5b is advancing (e.g. telescoping) towards and into abutment with the wellbore wall 2a.
  • Other tool advancing means such as a threaded, rotational configuration, are also envisaged.
  • Each tool 5 may comprise distance-sensing means (not shown), by which the distance travelled by the tool may be monitored. Alternatively, such sensing means may be integrated in the individual arm 6. It should be understood that the distance-sensing means may comprise generally known devices, including optical, acoustic and electromechanical means. The distance-sensing means will enable the device operator to determine the distance between the casing and the adjacent wellbore wall 2a, thus being able to evaluate whether or not a sufficient clearance between casing and wellbore wall exists.
  • the tools 5 have been advanced further through their respective casing penetrations, towards the wellbore wall 2a.
  • the casing is pushed away from the wellbore wall 2a when the tool is abutting the formation.
  • this is seen as the casing 1 has been pushed away from the wellbore wall by the tool 5' (towards the right in the figure).
  • the distance-sensing means are also in effect casing verification means, inasmuch as they will communicate the extended distance for each tool, and hence the minimum distance between the casing and the wellbore wall.
  • Figure 6 illustrates an alternative embodiment of the tool, being a deformable plug 5c, pressing against the formation wall.
  • Figure 4 shows the casing 1 centralized in the wellbore and thus forming an annulus 3 with the wellbore (formation) wall 2a.
  • the tools 5 have been disconnected from their individual arm, and the device has been retrieved to an uphole location.
  • the tools thus function as permanent casing centralizers, and cement (or other barrier element) 8 is placed into the annulus 3.
  • Each tool 5 is disconnectable from its individual arm by means that are known per se.
  • the device and tools may be integrated with an additional tool (not shown), whereby a well barrier placement operation may be performed following the verification and centralization procedure.
  • Figure 7 illustrates another embodiment of the invented device 41, having a tool section 41a and a milling section 41b.
  • the device is conveyed into the casing 1 and controlled via a drill string 10 (or coiled tubing, or similar).
  • the tool section 41a carries a first (upper) wedge set 52 and a second (lower) wedge set 53.
  • the milling section 41b which is rotatably connected to the tool section, carries a set of milling arms 51. It should be understood that each set comprises a plurality of wedges and milling arms, respectively.
  • the milling section 41b is rotated (as indicated by arrow R) with milling arms 51 in a deployed position, in a manner well known in the art, thus generating a first (upper) circumferential casing window 54 (see figure 8).
  • the device has been lowered further into the casing 1, and the second wedge set 53 has been entered (rammed or pushed) into the annulus 3, through the first casing window 54.
  • the connection between the first wedge set 53 and the tool section 41 is severed (e.g. sheared), and the device is being moved further into the casing, to a position shown in figure 9.
  • the milling section 41b is once again rotated (as indicated by arrow R) with milling arms 51 in a deployed position, to generate a second (lower) circumferential casing window 55 (see figure 10).
  • the device has been lowered further into the casing 1, and the first wedge set 52 has been entered (rammed or pushed) into the annulus 3, through the second casing window 55.
  • the connection between the first wedge set 53 and the tool section 41 is severed (e.g. sheared), and the device may be retrieved from the casing, e.g. to an uphole location.
