Disclosed is a process of manufacturing a lightweight particulate cementitious composition particularly adapted to the sorption of liquids comprising adding to a foamed cement slurry a particle forming agent, and aging the treated foamed slurry for a period of time sufficient for the particles to form and harden for subsequent handling. The bulk density, particle size distribution, and concentration of the agent are selected such that the cementitious composition has the desired density and such that at least 65% of the particles obtained after aging have the desired particle size.

Lightweight particulate cementitious materials and process for producing

The invention provides well working fluid compositions containing cotton burrs ground to certain particle size ranges to decrease the seepage loss of the fluid to fluid permeable formations contacted by the compositions. Also provided is a seepage loss additive comprising the ground cotton burrs in combination with one or more of ground oat hulls, ground corn cobs, hydrophobic organophilic water wettable cotton, ground citrus pulp, ground peanut shells, ground rice hulls, and ground nut shells.
