reservoirs that occur along ancient rivers where the rivers overflowed. Deposits are mostly silt and mud.

n: the condition in which the feeding amount is over the feeding ability of the vibrosieve and centrifuge

n: refer to”overflow“

n: those workers on a drilling or workover rig who work primarily on the rig floor. See rotary Mlper.

n: the drilling crew or clean crew who work in the drilling platform alternately

n: most commonly worn by sport divers to overcome the buoyancy effect of water and keep them afloat in the proper position. Carbon dioxide cartridges inside the vest are fired when inflation is necessary.

n: a kind of float collar which can inject fluid into the casing from the bottom and can close automaticly to prenent the overflow entrying the casing when the overflow from the under layer leads to jetting rate greater than the predicated value

n: a kind of highboy clean-up system for entire fluid ，equipped with vibrosieve，dust remover，sand remover ，mud remover and centrifuge

n: large pipe used in creek and stream ditching in pipeline construction to allow the water to flow normally and to provide a passage for equipment over the water.

n: on a mechanical engine governor, one of usually two small metal weights that spin as the engine runs. When the engine speeds up, centrifugal force on the spinning flyweights increases, which causes a spring to compress and slow the engine down. Conversely, when the engine slows down, centrifugal force on the flyweights decreases which causes the spring to expand and speed the engine up.

n: the force exerted by fluids in a formation, recorded in the hole at the level of the formation with the well shut in. Also called reservoir pressure or shut-in bottomhole pressure.

n: the pressure exerted by the formation fluids at a particular point in the formation,sometimes called reservoir pressure or pore pressure.

the pressure of the fluid in the formation. The initial reservoir pressure is the pressure at discovery.
