Abstract: A construction board comprising of a foam body, said foam body having first and second planar sides; and a facer affixed to said first or second planar surface, said facer including a cellulosic substrate and a water-resistant coating layer, said cellulosic layer having first and second planar sides, where said first planar side of said cellulosic substrate is affixed to said foam body and said second planar side carries said coating, where said cellulosic substrate is substantially devoid of fiberglass, where said water-resistant coating layer has a thickness of less than 1.5 mm, and where said water-resistant coating layer includes a polymeric binder and a filler dispersed throughout the binder.

Abstract: A water base drilling fluid additive contains biodiesel, lime, calcium chloride and solids for improving viscosity of the drilling fluid, while containing biodegradable ingredients. The additive also contains a weighting agent, for instance barite, a well bore sealant, such as bentonite, and an emulsion stabilizer, such as is lignosulfonate.

Abstract: A well drill lubricant and shale stabilizer employs a sugar alcohol, such as glycerin or crude glycerol and graphite beads suspended in the liquid alcohol. A viscosity agent, such as a gum, is added to improve viscosity along with water. Some impurities present in crude glycerol, such as ash, methanol and MONG are present in small amounts. The composition is non-toxic, fully biodegradable, while possessing high coefficient of lubricity.
