Definitions

  • the invention relates to a method for processing a well and, in particular, a method for drilling and cementing a well.
  • a casing string is used as the drill string so that once the well is drilled, the casing string can remain downhole to line the wellbore. This avoids the need for a separate operation to trip in a well bore liner after the well bore is drilled.
  • the present invention provides a method for drilling and cementing a borehole to access at least a portion of a formation of interest, comprising: drilling a borehole using a drill string including an external packer and a drilling assembly to access at least a portion of a formation of interest; using a drilling fluid selected to minimize adverse effects on the at least a portion of the formation of interest when drilling into the at least a portion of the formation of interest; setting the packer to create a seal in the borehole so that (i) an upper drill string/borehole annulus above the packer is isolated from (ii) a lower drill string/borehole annulus below the packer, with the at least a portion of the formation of interest being open to the lower drill string/borehole annulus; and introducing cement above the external packer into the upper drill string/borehole annulus.
  • the present invention provides a method for drilling and cementing a borehole to access at least a portion of a formation of interest, comprising: drilling a borehole using a drill string including an external packer and a drilling assembly to access at least a portion of a formation of interest, the drilling process including tripping the drilling assembly to surface and reintroducing the drilling assembly during drilling; setting the packer to create a seal in the borehole so that (i) an upper drill string/borehole annulus above the packer is isolated from (ii) a lower drill string/borehole annulus below the packer, with the at least a portion of the formation of interest being open to the lower drill string/borehole annulus; and introducing cement above the external packer into the upper drill string/borehole annulus.

  • a borehole can be drilled to access a formation of interest.
  • a formation of interest herein is that which is desired to be protected from harmful fluid contact therewith.
  • a formation of interest may therefore include a fragile formation, such as one that has a low pressure or one that is highly porous.
  • the formation of interest may be in various states such as a newly accessed formation or a depleted formation.
  • the borehole may be drilled with a drill string and a drilling assembly including an external packer which, when desired, may be positioned and may be set to seal the borehole relative to the formation of interest so that the drill string/borehole annulus above the packer is isolated from the drill string/borehole annulus below the packer.
  • a drilling fluid may be used that is selected to minimize adverse effects on the formation.
  • cement may be added above the packer.
  • the invention relates in one embodiment to a method of drilling, casing, and cementing a wellbore where the casing is carried along with or used as at least a portion of the drill string, an external casing packer is carried on the casing and may be set to form a seal in the annulus between the casing and the borehole after drilling of at least a portion of that borehole and before cement is introduced.
  • Cement may be pumped into the annulus between the casing and the borehole above the packer after the packer creates a seal in the casing/borehole annulus, so that a potentially damaging hydrostatic head of liquid (packer setting fluid and/or cement) is substantially prevented from being communicated to a formation of interest positioned relative to, which is generally below, the packer.
  • the borehole can be drilled into or through a formation of interest, of which at least a portion thereof is desired to be protected.
  • the packer may be positioned and may be set to seal the borehole relative to the formation of interest.
  • the packer may be positioned above any portion of the formation of interest that is sought to be protected to isolate the casing/borehole annulus above the packer from that portion of the formation of interest, which may be open to the casing/borehole annulus below the packer.
  • a drilling fluid may be used that is selected to minimize adverse effects to the formation such as, for example, by drilling the borehole substantially without putting a damaging hydrostatic pressure head on the formation of interest and/or avoiding the use of fluids that adversely chemically react with the materials of the formation of interest.
  • a drilling fluid may be for example, underbalanced relative to the formation of interest to thereby have a lower hydrostatic pressure than the pressure of the formation of interest or of a chemical state or composition selected to substantially avoid an adverse affect on the formation of the interest.
  • a foam-type drilling fluid may be used.
  • a gaseous- based drilling fluid may be used, which may be substantially dry.
  • a low density, compressible drilling fluid can be used including, for example, air, nitrogen, natural gas, or a mixture of any of these fluids.
  • a drilling fluid comprised substantially entirely of air may be useful.
  • consideration may also be given to the method by which the packer is set so that the formation is not damaged by this action.
  • the packer may be set by setting the casing down in the borehole, by hydraulic actuation or by inflation. If a compressible fluid is used as the drilling fluid, consideration may be given to methods for setting the packer since compressible fluids may not be capable of use to set a packer. If it is not desirable to set the drill string down on bottom, then care may be necessary to avoid exposing the formation of interest to a damaging packer setting fluid. For example, some packers require the use of non-compressible, higher density, liquid-based fluids to hydraulically set them.
