System Maintenance
The system should be maintained in a manner similar to that described for the CARBO-FAST /
CARBO-TEC system previously described.
SYN-TEQ Synthetic Base Drilling Fluid System
The SYN-TEQ system provides superior performance and environmental acceptability in one
synthetic-based drilling fluid. The system is based upon the use of a low-viscosity olefin isomer.
Baker Hughes Drilling Fluids ISO-TEC ® base fluid is a nontoxic, isomerized olefin designed
specifically for synthetic drilling fluid applications. The ISO-TEC base fluid is a biodegradable fluid
and is combined with other specialized fluid additives to form the SYN-TEQ system that offers a safe
alternative to traditional oil muds. SYN-TEQ systems can be formulated with low SWR
(synthetic/water ratio) for cost savings and overall enhanced well economics.
The SYN-TEQ system offers several environmental and logistical advantages over traditional oilbased
muds. Also the system delivers superior lubricity and increased thermal stability. Together,
these advantages make SYN-TEQ a preferred drilling fluid where the superior performance of a nonaqueous
fluid is desired and where the use of an oil-base fluid is prohibited by environmental
concerns. The SYN-TEQ system passes strict environmental testing, including toxicity and
biodegradability, designed to evaluate any environmental impact.
System Maintenance
The system should be maintained in a manner similar to that described for the CARBO-FAST /
CARBO-TEC system previously described.
SYN-TEQ CF Synthetic Base Drilling Fluid System
The SYN-TEQ CF non-aqueous drilling fluid system is designed specifically to allow the continuous
discharge of drill cuttings to the sea. SYN-TEQ CF is compliant with the National Pollutant
Discharge Elimination System (NPDES) permit for the Western Gulf of Mexico (2/12/02).
SYN-TEQ CF is formulated with a minimum number of products chosen specifically for individual
performance characteristic. The system can be used in any drilling operation requiring superior
performance, and is recommended for deepwater operations.
SYN-TEQ CF represents an environmental advance over previous non-aqueous systems using olefins
as the base fluid. SYN-TEQ CF is formulated from the base fluid C16/18 isomerized olefins which
are acknowledged by the US EPA as being an environmental benchmark in the Gulf of Mexico.
System Maintenance
The system should be maintained in a manner similar to that described for the CARBO-FAST /
CARBO-TEC system previously described.
GEO-TEQ Synthetic Base Drilling Fluid System
GEO-TEQ is a specially formulated, environmentally responsible synthetic drilling fluid system which
addresses the drilling performance, environmental, and geochemical needs desired in synthetic
systems. Accordingly, GEO-TEQ uses GT-2500 as the base fluid, which through its unique
composition will not interfere with the interpretation of naturally occurring hydrocarbon components
during crude oil analysis. Particularly, GT-2500 enables accurate analysis of the “bio-markers”,
Pristane and Phytane, even when the base fluid constitutes as much as 25% of the reservoir sample.
GEO-TEQ is a synthetic drilling fluid system specifically designed to allow continued discharge of
drill cuttings to the sea and is compliant with the National Pollutant Discharge Elimination System
(NPDES) permit for the Western Gulf of Mexico.
