n: any of several substances - usually organic compounds of high molecular weight-that, when added in low concentrations to a bentonite or to certain other clay slurries, will increase the viscosity of the system. See low-solids mud.

n: The material increasing viscosity by adding into the clay slurry.

a drilling additive to increase the viscosity of water based muds gelled with bentonite.

n: a system in which the gas pressure in the mains and the service lines is substantially the same as that delivered to the customers appliances;ordinarily, a pressure regulator is not required on individual service lines. low-solids fluid n: see low-solids mud.

n: a drilling mud that contains a minimum amount of solid material (sand, silt, and so on) and that is used in rotary drilling when possible because it can provide fast drilling rates.

n: a degignation given to any type of mud where high performing additives e.g.,cmc, have been partially or wholly substituted for commercial or natural clays. For comparable viscosity and densities (weighted with barite),a low-solids mud will have a lower v
