The mud then carries the crushed or cut rock ("cuttings") up the annular space ("annulus") between the drill string and the sides of the hole being drilled, up through the surface casing, where it emerges from the top. Cuttings are then filtered out with either a shale shaker or the newer shale conveyor technology, and the mud returns to the ...
a deep, broad trench, either dry or filled with water, surrounding and protecting a structure, installation, or town. Mud puddle: Nant: Stream: Wales. [33] Ocean: a major body of salty water that, in totality, covers about 71% of the Earth's surface. Oxbow lake: a U-shaped lake formed when a wide meander from the mainstem of a river is cut off ...
The Osceola Lahar produced by Mount Rainier in modern-day Washington some 5600 years ago resulted in a wall of mud 140 metres (460 ft) deep in the White River canyon and covered an area of over 330 square kilometres (130 sq mi), for a total volume of 2.3 cubic kilometres (1 ⁄ 2 cu mi). [7]
Mud volcano – Landform created by the eruption of mud or slurries, water and gases; Oceanic trench – Long and narrow depressions of the sea floor; Pull-apart basin – Type of basin in geology; Rift valley – Linear lowland created by a tectonic rift or fault; Sand boil – Cone formed by the ejection of sand on a surface from a central point
Large masses of material are moved in debris flows, hyperconcentrated mixtures of mud, clasts that range up to boulder-size, and water. Debris flows move as granular flows down steep mountain valleys and washes. Because they transport sediment as a granular mixture, their transport mechanisms and capacities scale differently from those of ...

Mud (probably from Middle Low German mudde, mod(de) 'thick mud', or Middle Dutch) [1] is loam, silt or clay mixed with water. It is usually formed after rainfall or near water sources. Ancient mud deposits hardened over geological time to form sedimentary rock such as shale or mudstone (generally called lutites ).
In the oil industry, mud weight is the density of the drilling fluid and is normally measured in pounds per gallon (lb/gal) (ppg) or pound cubic feet (pcf) . [1] In the field it is measured using a mud scale or mud balance. Mud can weigh up to 22 or 23 ppg. A gallon of water typically weighs 8.33 pounds (or 7.48 ppg).
