Definitions

  • the present disclosure relates to artificial lift systems, and related apparatuses, for use in producing hydrocarbon-bearing reservoirs.
  • Gas interference is a problem encountered while producing wells, especially wells with horizontal portions. Gas interference results in downhole pumps becoming gas locked and/or low pump efficiencies. Downhole packer-type gas anchors or separators are provided to remedy gas lock.
  • packer-type gas anchors are generally not design to effectively separate and manage debris. They are also relatively expensive.
  • the packers on packer- type gas anchors are susceptible to having debris accumulate thereon and, as a result, becoming stuck within the wellbore tubular against which it forms a seal and/or reducing their ability to separate gas or blocking flow passages within the packer-type gas anchor.
  • a stuck packer makes it difficult to remove production tubing from the wellbore or to access the wellbore below it, such as during a workover. Such attempt at removal may also damage the packer or wellbore casing, thereby rendering the packer-type gas anchor unusable for future production or even loss of the wellbore.

  • the wellbore may be completed either as a cased-hole completion or an open-hole completion.
  • Well completion is the process of preparing the well for injection of fluids into the oil reservoir, or for production of reservoir fluid from the oil reservoir. This may involve the provision of a variety of components and systems to facilitate the injection and/or production of fluids, including components or systems to segregate oil reservoir zones along sections of the wellbore.
  • "Reservoir fluid" is fluid that is contained within an oil reservoir. Reservoir fluid may be liquid material, gaseous material, or a mixture of liquid material and gaseous material. In some embodiments, for example, the reservoir fluid includes water and hydrocarbons, such as oil, natural gas, or combinations thereof.

  • the wellbore casing includes one or more casing strings, each of which is positioned within the well bore, having one end extending from the well head.
  • each casing string is defined by jointed segments of pipe. The jointed segments of pipe typically have threaded connections.
  • a wellbore typically contains multiple intervals of concentric casing strings, successively deployed within the previously run casing. With the exception of a liner string, casing strings typically run back up to the surface.
  • a production tubing string is usually installed inside the last casing string.
  • the production tubing string is provided to conduct reservoir fluid, received within the wellbore, to the wellhead.
  • the annular region between the last casing string and the production tubing string may be sealed at the bottom by a packer.
  • the wellbore casing may be perforated, or otherwise include per-existing ports, to provide a fluid passage for enabling flow of reservoir fluid from the reservoir to the wellbore.
  • the wellbore casing is set short of total depth.
  • the liner string can be made from the same material as the casing string, but, unlike the casing string, the liner string does not extend back to the wellhead.
  • Cement may be provided within the annular region between the liner string and the oil reservoir for effecting zonal isolation (see below), but is not in all cases.
  • this liner is perforated to effect fluid communication between the reservoir and the wellbore.
  • the liner string can also be a screen or is slotted.
  • the production tubing string may be stung into the liner string, thereby providing a fluid passage for conducting the produced reservoir fluid to the wellhead.
  • no cemented liner is installed, and this is called an open hole completion.
  • Open-hole completion is effected by drilling down to the top of the producing formation, and then casing the wellbore. The wellbore is then drilled through the producing formation, and the bottom of the wellbore is left open (i.e. uncased), to effect fluid communication between the reservoir and the wellbore.
  • Open-hole completion techniques include bare foot completions, pre-drilled and pre-slotted liners, and open-hole sand control techniques such as stand-alone screens, open hole gravel packs and open hole expandable screens. Packers can segment the open hole into separate intervals.
