The non aromatic oils of the VASSA™ LP Serie are used in the formulation of fluids for oil drilling muds. They are hydrogenated, obtained by a catalytic process at high temperature and pressure. This means that only saturated hydrocarbons of high and medium molecular weight are present in their composition. They are colorless and have a musty smell, characteristic of saturated hydrocarbons.

Because of their purity, these oils have been classified as "Enviroment Friendly Oils." As such they are used in wells where there is a risk of contamination of surface or underground water, or the need to reduce the environmental impact in case of spills. Additionally, toxicity tests carried out on these products show that VASSA™ LP Serie are non-toxic, making them a very low health risk.

Bioassays results, aerobic as well as anaerobic, make them suitable to be used in certain off-shore operations.

VASSA™LP Serie offers significant advantages compared to diesel based fluids. Among which are:

Prevent environmental damage to the soil, flora, and
     fauna.
Prevent health risks to drilling personal.
Reduce pollution of mud banks.
Reduce the cost of cuttings washing.

VASSA™ LP Series oils for drilling fluids, are produced in different grades according to their use:

VASSA™ LP 70 and VASSA™ LP-70P are recommended for well drilling in areas where the formations are well drained. The low specific gravity of VASSA™ LP 70P allows the formulation of ultra low density drilling fluids, thus minimizing the damage caused to the formation.
VASSA™ LP-90 represents the base grade to satisfy a wide range of requirements in the petroleum drilling industry.
VASSA™ LP-100 represents an intermediate grade to fulfill a wide range of requirements under the most diverse variety of conditions for drilling.
VASSA™ LP 120 is adequate for the manufacturing of drilling fluids being used in deep wells that reach a temperature over 380°F.
