n: one of a series of open tanks, usually made of steel plate, through which the drilling mud is cycled to remove sand and fine sediments. Additives are mixed with the mud in the tanks, and the fluid is temporarily stored there before being pumped back into the well. Modem rotary driJ1ing rigs are gen- erally provided with ~ or more tanks, fitted with txlilt-in piping, valves, and mud agitators. Also called mud pits.

n: see drilling fluid tank.

n: see viscosity.

n: 1. a massive, blocky rock composed of approximately equal proportions of clay and silt, but lacking the fine lamination of shale.2. in general, rock consisting of an indefinite and variable mixture of clay, silt, and sand particles.

sedimentary rocks that consist of particles finer than sand grade (less than 0.0625 mm) and include both silt and clay grade material. Also called shales.

when two or more gas lift valves are flowing gas at once.

n: drilling rate equation that establishes on the comprehensive effection on the mechanic speed , which composes two or more variable.

a survey conducted using 3-component geophones for sensing seismic reflections in the vertical, horizontal, and crossline directions (3-C). In the marine environment, a hydrophone is included to acquire 4-component (4-C) data.

n: the tool that connects drill stem test tool ( DSTT ),which can multiple operation and collects the fluid, volumn or pressure data of layer.
