Definitions

  • the present invention relates to drilling operations such as oil and gas well drilling or geothermal drilling and more particularly to the handling and transport of cuttings that are generated during drilling operations offshore and onshore. Even more particularly, the present invention relates to a system and a method for handling of cuttings/rock cuttings/drilled solids that are generated during drilling activity.
  • Such a system and method may, for instance, be used during drilling operations such as oil and/ or gas well drilling operations, geothermal drilling operations, or even after such drilling operations have been completed, for instance in connection with a transport needs arising subsequently after such drilling operations.
  • This transportation needs may be internally on the platform, between the platform and a vessel or also between a platform or vessel and a shore facility.
  • the vessel may be a ship, a drillship, a FSPO, a barge, a supply ship or the like, and the platform may be an oil and/ or gas well platform, a rig or the like.
  • the handling and transportation of the cutting may be done offshore, onshore or subsea.
  • Oil rigs typically employ a drilling rig or derrick that extends above the well drilling platform and which can support joint after joint of drill pipe connected end to end during the drilling operation.
  • the drill pipe or drill string thus comprises a plurality of joints of pipe, each of which has an internal, longitudinally extending bore for carrying fluid drilling mud from the well drilling platform through the drill string and to a drill bit supported at the lower or distant end of the drill string.
  • Drilling mud lubricates the drill bit and carries away well cutting generated by the drill bit as it digs deeper.
  • the cuttings are carried in a return flow stream of drilling mud through the well annulus and back to the well drilling platform at the earth's surface.
  • the drilling mud reaches the surface, it is contaminated with small pieces of shale and rock, which are known in the industry as well cutting or drill cuttings.
  • Cuttings have in the past been separated from the reusable drilling mud with commercially available separators that are known as shale shakers.
  • Other solids separators include mud cleaners and centrifuges.
  • Some shale shakers are designed to filter coarse material from the drilling mud while other shale shakers are designed to remove finer particles from the well drilling mud.
  • the drilling mud is returned to a mud pit where it can be supplemented and/or treated prior to transmission back into the well bore via the drill string and to the drill bit to repeat the process.
  • Drill cuttings contain not only the mud product that would contaminate the surrounding environment, but also can contain oil that is particularly hazardous in the environment, especially when drilling in a marine environment. Oil and gas drilling operations produce drill cuttings or tailings that consist of material removed from a well with mixtures of other fluids and materials that are used to facilitate drilling. This other material is typically called drilling mud.
  • US 6.988.567 B2 regards methods for moving drilled cuttings using a cuttings processor with a rotating annular screen to separate fluid from drilled cuttings and/ or such methods including conveying with air under positive pressure, drilled cuttings to flow conduit apparatus; applying air under positive pressure to the flow conduit apparatus; applying air under positive pressure to the flow conduit apparatus to continuously move the drilled cuttings material therethrough;
  • the separation apparatus continuously moving the drilled cuttings material with the air under pressure to separation apparatus; with the separation apparatus continuously separating drilled cuttings from air; wherein, in certain aspects, the drilled cuttings are included in a low density slurry with drilling fluid, drilling mud and/ or oil and wherein, in certain aspects, the separation apparatus is a cyclone separator and the drilled cuttings moved into the cyclone separator are wet; and systems for effecting such methods.
  • WO 93/20328 Al regards a method and an apparatus for processing oily cuttings generated at a well site in order to produce a slurry suitable for injection into a subsurface formation.
  • the oily cuttings are agitated with seawater in, for example, a primary mixing tank, which contains an agitator.
  • the mixture is then pumped, using pumping means, to a roller mill grinding means at which the mixture is ground in such a way that particles of greater size are proportionally degraded more than particles of smaller size.
  • the solid-rich slurry emerging from the grinding means is fed to a slurry tank at which, if necessary, seawater and/or chemicals are added to produce a slurry of desired rheological properties suitable for injection into the formation.
  • GB 2.330.600 A regards a method of treating solids generated during a drilling process for storage and transportation.
  • Drilling mud is supplied to a platform, by pumping from a supply ship.
  • By-products such as oily cuttings, are transported by the ship back to a shore-based cuttings processing facility, where the oily cuttings are cleaned.
  • the cuttings are mixed with a drilling mud based, thixotropic carrier fluid, to form a slurry.
  • the slurry is stored in a retention tank located low down on the platform, and pumped into a tank on a ship which has conveyed drilling mud to the platform, for transporting the slurry to a shore based retention tank into which it is pumped from the ship's tank.
  • On-shore processing involves separating the cuttings from the carrier fluid, and cleaning the cuttings for dumping.
  • Agitation means for agitating the slurry, to prevent solids settlement, are provided in the platform slurry retention tank.
  • Pipe means for conveying slurry to and drilling mud from the storage tank on the supply vessel, and pump means for pumping said slurry to the storage tank, through the said pipe means, are also provided.
  • One solution to the above systems may be pneumatic transport systems, but also such pneumatic systems suffer from several drawbacks such as high noise level, high powered compressors, high risk associated with pressurized facilities and large energy storage in very bulky air and storage tanks, which are expensive to purchase or maintain in production in that they are material-consuming and labor intensive, together with such systems are subject to strict certification regimes, especially with regards to explosion hazards, Pressure Equipment Directive (PED) etc.
