The process in which reservoir fluids are caused to flow out of the reservoir rock and into a wellbore by natural energy.

Gas drives depend on the fact that, as the reservoir is produced, pressure is reduced, allowing the gas to expand and provide the driving energy.

Water-drive reservoirs depend on water pressure to force the hydrocarbons out of the reservoir and into the wellbore.

A device closed around the rods when the well may flow through the tubing while the rods are being pulled.

It is a form of blowout preventer.
