Manual Lube 100

LUBE 100LUBE-100 lubricant reduces torque, drag and the potential for differential sticking by reducing the coefficient of friction of water-base muds. It can also provide additional wellbore stability and inhibition, reduce bit-balling and improve high-temperature filtration control. LUBE-100 is only slightly water soluble under most conditions but is readily dispersible in water-base muds. It is acceptable for most situations specifying a low-toxicity lubricantTypical Physical PropertiesPhysical appearance- Amber liquidSpecific gravity- 0.98-1.04pH (3% solution)- 8.75Solubility in water- SlightFlash point- 430OF (221OC) (PMCC)ApplicationsLUBE-100 should be specified for those situations where torque, drag and/or the potential for differential sticking are likely, such as when drilling highly deviated or high-differential-pressure wells. This additive is especially useful for preventing the "stick-slip" condition in directional drilling when using the "slide" method without rotation. Normal concentrations of LUBE-100 range from 2 to 4% or 7 to 17.5 lb/bbl (20 to 50 kg/m3), depending on the mud density, desired reduction in coefficient  of friction and the mud system. After the initial treatment, periodic treatments should be made to maintain the desired concentration. Higher concentrations may be  needed for pills and special applications. Treatment levels and product usage will depend on the rate of penetration, solidscontrol equipment and dilution rates. Due to the potential for an increase in viscosity when added to lightlytreated, high-bentonite systems or to systems with high solids, heavy treatments of LUBE-100 should be  added slowly. If high viscosity occurs, circulation time and temperature cycling will restore the fluid to near-original conditions. While LUBE-100 does not affect the rheology of most mud systems, pilot testing is recommended as a precautionary measure for all initial applications and large treatments. LUBE-100 should be added slowly, directly  to the mud system wherever there is good agitation or through the mixing hopper. One suggested application method consists of maintaining a small, constant stream, added directly into the suction pit. LUBE-100 does not "grease," is resistant to contamination and is compatible with common water-base mud additives. Because the product has very low foaming potential, it will not cause foaming problems in the mud system. For offshore applications with LUBE-100 concentrations approaching 4%, the LC50  should be monitored closely.AdvantagesHighly effective downhole lubricant for reducing torque and dragReduces the potential for, and the severity of, differential stickingResists contamination and is compatible with other water-base additivesResists contamination and is compatible with other water-base additivesChemically stable downhole under pressure and at temperatures of more than 450OF (232OC)Reduces the tendency for bit and stabilizer balling when drilling gumbo clays.Can improve wellbore stability and inhibition, and help obtain more gauge holes.Helps improve high-temperature filtration controlHelps maximize rate of penetrationEnvironmentally acceptable for offshore useDoes not sheenLimitationsMay cause high viscosity when added to non-dispersed, lightly-treated bentonite or high-solids fluidsToxicity and HandlingBioassay information is available upon request.
