n: a cylindrical steel bar (similar to the handle or bail of a bucket, only much larger) that supports the swivel and connects it to the hook. Sometimes, the two cylindrical bars that support the elevators and attach them to the hook are called bails or links. v: to recover bottomhole fluids, samples, or drill cuttings by lowering a cylindrical vessel called a bailer to the bottom of a well, filling it, and retrieving it.

n: A rounded steel bar that supports the swivel and connects it to the hook. May also apply to the steel bars that connect the elevators to the hook (links).

remove solids or fluids from a well.

v: 1. to collect a mass of sticky consolidated material, usually drill cuttings, on drill pipe, drill collars, bits, and so forth. A bit with such material attached to it is called a balled-up bit. Balling up is frequently the result of inadequate pump pressure or insufficient drilling fluid. 2. in reference to an anchor, to fail to hold on a soft bottom, pulling out, instead, with a large ball of mud attached.

n: The phenomenon that drill bit or drill tool is surrounded by cutting and viscous mud in drilling progress.

the small chips and fines generated by drilling through a formation with a drill bit. Most of the cuttings are removed from the mud as the fluid pass through the solids control equipment (e.g., shakers, screens, cyclones, etc.,) at the surface.

n: Synonyms-cuttings transport, cuttings lifting.

transporting drill cuttings or fill to surface.

n: The time taken for cuttings to reach the surface The term is also used in place of cycle time.

The time it takes for drill cuttings to be carried to surface from the bottom of the well.

n: shortened form of shale shaker. See shale shake!:

n: The primary and probably most important device on the rig for removing drilled solids from the mud. This vibrating sieve is simple in concept, but a bit more complicated to use efficiently. A wire-cloth screen vibrates while the drilling fluid flows on to

a piece of drilling equipment, usually with a vibrating screen, where drill cuttings are removed from the flowing mud.

n: solid grains that suspending in the drilling fluid ,for example,drill cuttings ,clay particle ,barite etc.

n: The solid phase that can deteriorate the performance of drill fluid,for example ,drill cuttings.
