The invention is a fluid having a kinematic viscosity from 3 to 6 mm/s, a flash point of higher than 120° C. and a pour point lower than −40° C., having a boiling point in the range of from 200° C. to 400° C. and a boiling range below 80° C., said fluid comprising more than 95% isoparaffins and less than 3% of naphthens by weight, a biocarbon content of at least 95% by weight, containing less than 100 ppm aromatics by weight. The invention is also a drilling fluid and the use of the fluid to improve the viscosity of the drilling fluid.
