in a well work sense, usually a non-rig well entry using wireline or CT intervention where the well head remains attached. Rigs may be used. Compare to workover.

movement of one fluid into a permeable zone.

n: a kinds of effective hydrogen sulfide remover in fluid.

n: a method for removing small concentrations of hydrogen sulphide from natural gas by passing the gas over a bed of wood shavings that have been impregnated with a form of iron oxide (iron sponge). The hydrogen sulphide reacts with the iron oxide, forming iron sulphide and water.

n: a kinds of method that eliminate the hydrogen sulfide of natrual gas.

n: a governor that maintains a constant speed of the prime mover regardless of the load applied, within the capacity of the prime mover.

n: a geological map of subsurface strata showing the various thicknesses of a given formation as a series of contours. It is widely used in calculating reserves and in planning improved recovery projects.

integrated workover control system.

n: the configuration of pipe when it enters the water from an inclined ramp on the stem of a lay barge instead of from a stinger. The J curve eliminates overbend, which can stress the pipe.

n: 1. an oil well pumping unit that is powered by an internal-combustion engine, electric motor, or rod line from a central power source. The walking beam of the pumping jack provides reciprocating motion to the pump rods of the well. See walking beam.2. a device that is manually operated to turn an engine over for starting. v: to raise or lift.

n: the fitting that hoist the weight and equipment.

n: a mobile bottomsupported offshore drilling structure with columnar or open-truss legs that support the deck and hull. When positioned over the drilling site. the bottoms of the legs rest on the seafloor. A jackup rig is towed or propelled to a location with its legs up. Once the legs are firmly positioned on the bottom, the deck and hull height are adjusted and leveled. Also called self-elevating drilling unit.
