Definitions

  • the present invention relates to a method of installing a tubular element in a wellbore whereby the tubular element is radially expanded in the wellbore so as to form an expanded tubular section and an unexpanded tubular section, and whereby an annular space is formed between the tubular element and the wellbore wall .
  • casing is used to refer either to a wellbore casing or to a wellbore liner .
  • Wellbores for the production of hydrocarbon fluid generally are provided with one or more casings to stabilise the wellbore wall and/or to provide zonal isolation .
  • Cement is pumped into the wellbore to seal the annular space and to fix the casing in the wellbore .
  • several casings are set at different depth intervals , in a nested arrangement whereby the diameter of each subsequent casing is smaller than the diameter of the previous casing in order to allow lowering of the subsequent casing through the previous casing .
  • a casing is expanded to allow a larger available working space in the wellbore
  • a tubular element is expanded against an existing casing to form a tubular clad and to serve as a production conduit for hydrocarbon fluid
  • it has been proposed to construct a monodiameter well by radially expanding each casing to substantially the same diameter as the previous casing . It is thus achieved that the available inner diameter of the casings is substantially constant throughout the wellbore depth, as opposed to the conventional nested arrangement whereby the available diameter decreases stepwise with each subsequent casing .
  • the monodiameter concept is particularly of interest for very deep wellbores or for extended reach wellbores .
  • an expander of larger diameter than the inner diameter of the unexpanded tubular element is pumped, pushed or pulled through the tubular element , sometimes with combined rotation of the expander .
  • a method of installing an expandable tubular element in a wellbore comprising : lowering the tubular element into the wellbore whereby an annular space is formed between the tubular element and the wellbore wall; - locating a first compound in the annular space , the first compound being adapted to cooperate with a second compound upon contact therewith so as to form an annular body anchoring the tubular element in the wellbore ; radially expanding a section of the tubular element ; - inducing the second compound to enter a portion of the annular space surrounding said expanded tubular section; and disconnecting an unexpanded section of the tubular element from said expanded tubular section, and removing the unexpanded tubular section from the expanded tubular section .
  • the annular body is only formed in the portion of the annular space surrounding the expanded tubular section, so that only the expanded tubular section becomes anchored in the wellbore .
  • the unexpanded section of the tubular element has not become anchored in the wellbore, and therefore still can be removed from the wellbore or can be lowered through the expanded section deeper into the wellbore .
  • the annular body also functions to seal the expanded tubular section in the wellbore .
  • the tubular element preferably is provided with container means containing said second compound, wherein the container means is induced to release the second compound into said portion of the annular space upon radial expansion of said section of the tubular element .
  • the second compound can be released from the container means , for example, by deformation of the container means upon radial expansion of said section of the tubular element .
  • the container means preferably includes at least one annular container surrounding the tubular element . More preferably the container means includes a plurality of annular containers axially spaced along the tubular element , each container extending around the tubular element .
  • the container means is absent from said inlet section .
  • the first compound is removed from a portion of the annular space surrounding said inlet section .
  • the second compound is an activating compound and the first compound is a fluidic compound adapted to harden upon contact with the activating compound .
  • the fluidic compound can be adapted to slowly harden by itself, whereby the activating compound functions to accelerate the hardening process . In this manner it is achieved that the activating compound needs to be inj ected into the annular space at discrete locations only, instead of continuously along the length of the expanded tubular section .
  • the fluidic compound is subj ected to accelerated hardening at the discrete locations , thereby providing sufficient initial anchoring functionality for the tubular element . Full anchoring functionality is provided after hardening of the remainder of the fluidic compound by itself .
  • the annular body of hardened compound Apart from anchoring the tubular element in the wellbore , suitably the annular body of hardened compound also provides zonal isolation in the wellbore, i . e . the annular body prevents fluid communication between different earth layer traversed by the wellbore .
  • the fluidic compound and the activating compound are adapted to chemically react with each other so as to form said annular body.
  • the activating compound is a catalyst adapted to trigger or to accelerate hardening of the fluidic compound .
  • the term "fluidic compound” refers to a compound which can be pumped into the wellbore in a stream, for example a stream of liquid, a stream of solid particles , or a stream of solid particles in a carrier fluid .
  • Suitable systems of fluidic compound and corresponding activating compound for use in the method of the invention are the two-component systems outlined hereinafter .

  • the cement slurry can be Portland oil well cement ( ISO Classes A-H) , ground granulated blast furnace slag (GGBFS ) , or slagment which is a mixture of Portland cement and GGBFS .
  • Sodium Silicate can be used as the activating compound in these systems .
  • S-Mix is described in WO 94 /09249 ; WO 94 /09250 ;
  • the fluidic compound is a dormant cement slurry including GGBFS , either with or without Portland cement .
  • the activating compound can be an alkaline solution, such as Caustic Soda, Soda ash or Sodium Silicate solutions .
