OMNI-TEC ®
OMNI-TEC ® is an anionic emulsifier used with lime hydrate to provide temperature-stable emulsions
of water or brines in synthetic and oil-base fluid systems. OMNI-TEC exhibits a high tolerance to
contaminants and high temperatures. SYN-TEQ systems, prepared with OMNI-TEC, have been
formulated to withstand temperatures in excess of 400°F (204°C).
OMNI-TEC is compatible with a wide range of internal phase salinities and can be used to emulsify
calcium chloride and sodium chloride brines, seawater, and freshwater. OMNI-TEC, together with
lime hydrate, will provide moderate filtration control in synthetic-base fluids. OMNI-TEC contains no
aromatic solvents.
OMNI-TEC is the primary emulsifier used in the SYN-TEQ SM synthetic-base fluid system. It requires
lime to function effectively, and is used in conjunction with OMNI-MUL and filtration control
additives in this system. Together with lime, it is recommended for increasing the thermal and
electrical stability of all synthetic-base fluid systems.
OMNI-TEC controlled filtrate synthetic-base fluid systems will require 0.6 to 1.7 gal/bbl (14.3 to 40.5
L/m 3 ). Lime should be added as the activator at a concentration of 5 lb m lime per gallon of OMNI-
TEC (0.6 kg/L).
