High Temperature Fluid Loss Control Additive CAL-TROL


CAL-TROL is   a specially formulated Fluid Loss Control Additive for Water-Based Fluid Systems effective at high temperatures. It is primarily a Fluid Loss Control   Additive and an effective Viscosifier. It is nonionic and suitable for use in   fluids with salts or ion sensitive additives.


CAL-TROL when used with   bridging agent like sized calcium carbonate, it forms a thin easily removable   filter cake. It enhances Low Shear Rate Viscosity in water-based fluid   systems compared to other fluid loss control products like PAC or starch-based   additives. CAL-TROL can be used in most brines including   seawater, NaCl, KCl, CaCl2, NaBr and formate salt systems. It controls calcium contamination over a wide pH   range and can be used at temperatures to 330°F. At higher   bottom hole temperatures, a  thermal extender is recommended.


CAL-TROL  is Non Ionic, suitable for use in fluids with salts or ion sensitive additives. It functions as an effective Viscosifier for water-based fluid systems. CAL-TROL  provides a thin, easily removable filter cake which minimizes formation damage. It enhances Low Shera Rate Viscosity (LSRV). It is stable at higher temperatures.
