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: see shaker tank.

n: The tank near the shaker.The slurry come from the well come into this tank firstly.

n: the mud tank adjacent to the shale shaker. usually the first tank into which mud flows after returning from the hole. Also called a shaker pit.

n: a fine-grained sedimentary rock: composed mostly of consolidated clay or mud. Shale is the most frequently occur- ring sedimentary rock:.

n: a finely-grained sedimentary rock composed of silt- and clay- sized particles.

a common sedimentary rock with porosity but little matrix permeability. Shales are one of the petroleum source rocks. Shales usually consist of particles finer than sand grade (less than 0.0625 mm) and include both silt and clay grade material.

materials that slow or prevent the mechanical or chemical disaggregation of shale. These materials include inorganic salts and some organic compounds.

n: A kind of addition agent that can repress hydration,bloating and decentralizing.

n: It can indicate the relation of depth and the content of all kinds of minerals.

methane gas stored in a shale. May be in the pore space, adsorbed to the mineral or rock surfaces, or as free gas in the natural fractures.

n: see oil shale.

can be either a immature oil phase, often called Kerogen, or actual oil in the crocks of pores of a shale.

n: a series of trays with virbrating screens that allow the mud to pass through but retain the cuttings. The mesh must be chosen carefully to match the size of the solids in the mud.

a solids separation piece of equipment on a drilling rig that uses vibrating screens to remove solids from the returning mud.
