The Cognis Oleochemicals' solutions for oilfield chemicals not only comply with all applicable environmental regulations, but also provide superior technical performance and ensure greater safety for people and equipment as well.

Environment

Drilling fluids made with Cognis Oleochemicals esters obtained from palm kernel oil comply with all of the applicable environmental regulations. They ensure that the drilling fluids will be highly biodegradable and reduce the negative effects of oil and gas drilling to a minimum. This has been corroborated by the Leptocheirus Test, and the EQ Emblem vouches for it. Cognis esters also provide the drilling fluids with even better performance characteristics and increase safety for people and equipment.

Performance

The esters developed by Cognis Oleochemicals are extremely reliable and make drilling fluids cold-resistant, even for deep drilling operations. Drilling muds containing our products remain fully pumpable and lubricate the drill bit most efficiently, even in deep and very cold water, in all rock formation strata, and in highly complex deviated boreholes. And even when subjected to high pressure and extreme fluctuations in temperature, these Cognis products give drilling muds sufficiently low viscosity to ensure optimal drilling properties.

Safety

"Safety first" is the golden rule on drilling rigs. Drilling fluids containing esters based on renewable natural resources make work on deck safer, because the formulation

• has no irritating odor,
• is not toxic if inhaled,
• does not irritate the skin.
