Product Sheet LUBE 776
Reduces torque, drag, and the potential for differential sticking.
LUBE 776 lubricant effectively reduces torque, drag, and the potential for differential sticking by reducing the coefficient of friction in low-solids, nondispersed water-based drilling fluids and nonaqueous drilling fluids.
In one field application, after an initial addition of LUBE 776 lubricant at 2% by volume, rotary torque readings were reduced by as much as 33%. LUBE 776 lubricant also shows low foaming, greasing, and emulsion-forming potential.
|Typical Physical Properties|
|Physical appearance||Light yellowish liquid|
|Specific gravity||0.95–1.00 at 68 degF [20 degC]|

LUBE 776 lubricant is designed for situations where torque, drag, and the potential for differential sticking are likely to occur, such as when drilling highly deviated or high-differential-pressure wells. Normal concentrations of LUBE 776 lubricant range from 1% to 3 % by volume, or 3.5 to 10.5 lbm/bbl [10 to 30 kg/m3], depending on the fluid 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, solids-control equipment, and dilution rates.
Pilot testing is recommended to all additions especially applications in excess of 300 degF [149 degC].
Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions as described in the safety data sheet.
LUBE 776 lubricant is packaged in a standard pack unit: 200-L [52.8-galUS] drums or in bulk; other pack units on request. Store in a dry, well ventilated area. Keep container closed. Keep away from heat, sparks and flames, and store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrinkwrapping, and stacking.
