n: in drilling operations, gas that returns to the surface with the drilling mud in measurable quantities but does not cause a kick. Increases in background gas may indicate that the well is about to kick or has kicked.

n: a complete trip from the bottom of the wellbore to the top.

n: The process that the drilling fluid returns to the well head from the bottom hole.

circulating the bottom hole fluid to the top of the well.

n: The valves that make vibrosieve short out. The drill fluid which returns from wellbore enters into circulating system directly without sieving handling.

n: an electrical device that. when wired in the line of an electrical circuit, stores a charge of electricity and returns the charge to the line when certain electrical conditions occur. Also called a condenser.

n: an arrangement of piping and special valves, called chokes. In drilling, mud is circulated through a choke manifold when the blowout preventers are closed. In well testing, a choke manifold attached to the wellhead allows flow and pressure control for test components down- stream.

n: A set of high-pressure valves and associated piping that usually includes at least two adjustable chokes, arranged such that one adjustable choke may be isolated and taken out of service for repair and refurbishment while well flow is directed through the

a set of valves and/or chokes used to control drilling fluid returns on a drilling well or, in a few cases, used to control flow from a high rate well where the chokes may be in parallel or series.

n: The total time that drill fluid returns to the drill fluid pool through mud pump, swivel, drill pipe, drill bit, annular and purification plant.

n: The process that drilling fluid is pumped from the pool and returns to the pool through standpipe, drilling hose, drilling string ang bit.

n: The circulating method that the drilling fluid is pumped from annular and returns from drill pipe.

n: The drill fluid which returns to the surface with cuttings and has not been purified.

n: a bottle released at sea to measure currents. It contains a card stating the date and location of release. The person who finds the bottle writes on the card the date and location of the bottles recovery and returns the card. Also called a floater.
