Oil / Synthetic Fluids
MAGMA-TROL
MAGMA-TROL is a polymeric, oil soluble product designed for HTHP filtrate control and for use in
the environmental and occupational hygiene regulated MAGMA-TEQ HTHP oil-based drilling fluid
developed for use in drilling deviated North Sea wells. MAGMA-TROL is temperature stable to
greater than 1112º F (600º C). It works independently of the base fluid and has a secondary effect
benefit of suspension stabilization. MAGMA-TROL has been field tested to 458º F (237º C)

MAGMA-VERT
MAGMA-VERT is a specialized, high temperature, modified amide amine used as a supplementary
emulsifier in the MAGMA-TEQ HTHP oil-based mud system. MAGMA-TEQ is a specialized
system specifically developed for the drilling of HTHP deviated wells in the North Sea. The system
and its associated products such as MAGMA-VERT meet the stringent environmental and
occupational hygiene regulations established for this area.
OMNI-COTE ®
OMNI-COTE ® is a thinner and solids dispersing agent for synthetic- and oil-base fluid systems. It is
used to lower rheological properties in both CARBO-DRILL and SYN-TEQ systems if the fine solids
content becomes excessive.
Treatments with OMNI-COTE will vary depending on the type and quantity of drill solids in the fluid
system. Concentrations of 0.1 to 1.0 gal/ bbl (2.38 to 23.8 L/m 3 ) are typical levels used in the field.
All treatments should be pilot tested to determine the optimum level.
