n: a valve that shuts off or regulates fluid flow. v: to shut in intermittently to allow a build-up of gas pressure in a producing oilwell, which thus effects more efficient recovery.

n: a series of storage cells that produce electricity by chemical action of acid or alkaline solution on metallic plates. Charging the battery with DC electricity in the opposite direction restores the chemical condition necessary for further output of electricity.

n: a tank in which oil is stored pending transfer by pipeline, truck, or other vehicle for selling.

n: a tubing safety valve.

A flow controlled shut-in device to control flow in the event of loss of surface well control. Must be reset periodically. Replaced by ScSSVs.

n: a heavy-duty squeeze tool that can be closed to allow operations to cease during a severe storm offshore. Later, the tool can be opened to allow operations to continue.

n: a retrievable tool used to suspend drilling temporarily during a storm offshore.

n: a route traversed by lowpressure systems.

n: pollutants that are washed into water resources in storm situations. Such discharges are regulated under CWA.

n: a rotational shear viscometer used for measuring the viscosity and gel strength of drilling fluids. This instrument has been largely superseded by the direct-indicating viscometer.
