Use of selected fatty alcohols and mixtures with carboxylic acid esters as components of lubricants in sludge systems for water-based scan for terrestrial exploration thereof.

It DESCRIBED THE USE OF ALCOHOLIC LINEAR FATTY and / or branched with at least 12 carbon atoms in the molecule and / or use of mixtures of such fatty alcohols with carboxylic acid esters as an additive WITH ACTION LUBE SYSTEMS BASED WATER DRILLING FOR USE IN UNDERGROUND eXPLORATION THROUGH THE POLL. Lubricants are based on fatty alcohols or lubrication systems ARE PARTICULAR SUITABLE FOR USE IN SYSTEMS DRILLING SILICATO ALKALINE WATER BASED, characterized SO KNOWN FOR ITS high pH in the aqueous WASH SYSTEM. The additives of the invention combine HERE WITH AN ACTION EFFECT LUBRICANTE ANTIFOAM OR Inhibiting Foaming UNWANTED.
