BIODRILL(simil to DESCO CF) is an environmentally compatible, high performance, multipurpose mud conditioner for rheology control in water base muds. It is a modified tannin compound that replaces chrome lignosulfonates. BIODRILL thinner works other additives fail. The absence of added use the chrome makes this suitable, for use in areas where environmental concerns may limit the presence of chrome in drilling fluid systems. Mud types: Most water-soluble formulations. Applications: Is used as thinner (deflocculant), to stabilize the rheology to reduce flow properties, in all kinds of water based drilling fluids. Provide effective control of filtration rates, of water-based muds approaching **0 F ( **4 C ). Advantages: Environmentally compatible. It is not polluting Maximum deflocculation and shear strength reduction at low concentrations. Soluble is systems of high salinity, high hardness and at any pH. Significantly more effective than chrome lignosulfonates, depending on conditions- **8 times more effective. Scavenges oxygen and inhibits corrosion. High temperature rheology control proven effective in excess of **0 F ( **4 C ). Solutions pH is 8, 5 *- no caustic needed to activate. So much acts with sodium bentonitas as that calcium To high temperatures it prevents the polymerization of the natural clays Filtrate reducerIt can be used in surface and to depths of but of ****0 feet and todifferent densities APPLICATIONS MATERIAL NEEDED Top hole and low solids, semi-dispersed muds 1 to 5 ppb (.3 to 2 kg/m3)Supplement lignosulfonate, lignite muds Ratio of 4 lignosulfonate to 1 Biodrill Deep, hot drilling where lignosulfonate degrade Ratio of 4 lignite to 1 Biodrill Conditioning drilling muds for packets fluids (any density) 0, 5 to 3 ppb (2 to 9 kg/m3) for shear strength control Saturated salt, inhibited, or contaminated muds 0, *5 to 3 ppb ( 0, 7 to 9 kg/m3) Mixing Requirements: Mix through hopper
