Definitions

  • Embodiments of the present invention generally relate to a valve for use in a wellbore. More particularly, this invention pertains to a deepset wireline retrievable safety valve for controlling fluid flow through a production tubing string.
  • Deep set safety valves are commonly used to shut in oil and gas wells. Such safety valves are typically fitted into production tubing in a hydrocarbon producing well, and operate to block the flow of formation fluid upwardly through the production tubing should a failure or hazardous condition occur.
  • Deep set safety valves may be configured as rigidly connected to the production tubing (tubing retrievable), or may be installed and retrieved by wireline, without disturbing the production tubing (wireline retrievable).
  • a problem arises when the valve is positioned deep within the wellbore (>6000 feet) because the components in the valve are unable operate due to hydrostatic pressure of the fluid in a control line connected to the valve and the wellbore pressure.
  • the present invention generally relates to a deepset wireline retrievable safety valve for controlling fluid flow through a production tubing string.
  • a valve for use in a wellbore is provided.
  • the valve includes a housing having a bore.

The first force and the second force are applied to the actuator sleeve in an opposite direction.

  • the biasing member 120 is designed and selected to overcome hydrostatic pressure of the fluid in the control line 1 12.
  • hydrostatic pressure is a pressure exerted by a fluid at equilibrium due to the force of gravity.
