Title
(EN) ENVIRONMENTALLY FRIENDLY ESTER-STRUCTURES AS VISCOSIFIER FOR OIL BASED DRILLING FLUIDS
(FR) STRUCTURES D'ESTER ECOLOGIQUES COMME AGENT VISCOSANT DE FLUIDES DE FORAGE A BASE D'HUILE
Abstract
(EN)
The present invention relates to a mixture of esters obtainable by reacting
components of an
esterifiable composition with each other, wherein the esterifiable composition
comprises at
least one trimer fatty acid, at least one fatty acid and at least one hydroxy
monocarboxylic
acid and a production process of the mixture of esters. Furthermore, the
present invention
relates to environmental friendly, preferably oil based, drilling fluids
comprising the abovementioned
mixture of esters, water and an organic phase and the use of said mixture as
viscosifier for drilling fluids.
