Definitions

  • Hydrocarbon fluids such as oil and natural gas are obtained from a subterranean geologic formation, referred to as a reservoir, by drilling a well that penetrates the hydrocarbon-bearing formation. Once a wellbore has been drilled, the well must be completed before hydrocarbons can be produced from the well. A completion 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. After the well has been completed, production of oil and gas can begin.
  • Sealing systems such as packers or anchors, are commonly deployed in a well as completion equipment.
  • Packers are often used to isolate portions of a wellbore from one another.
  • packers are used to seal the annulus between a tubing string and a wall or casing of the wellbore, isolating the portion of the wellbore above the packer from the portion of the wellbore below the packer.
  • Packers can be actuated by hydraulic pressure transmitted either through the tubing bore, annulus, or a control line.
  • Other packers can be actuated via an electric line deployed from the surface of the wellbore.
  • packers have been used that employ elements that respond to the surrounding well fluids and swell to form a seal. Swellable packers can swell from an unexpanded state to an expanded state, thereby creating a seal, when the swellable material comes into contact with a triggering fluid.
