Abstract

This paper presents static oil/brine contact angles measured using the sessile drop method on soda lime glass and polished marble. Pure n-decane and three 66 mM naphthenic acid solutions in n-decane were considered as model oils. Selected naphthenic acids were: cyclohexanecarboxylic acid (CHCA), cyclohexanebutyric acid (CHBA), and cyclohexanepentanoic acid (CHPA); all oils were dyed with Oil Red O (ORO) at a concentration of 0.9 mM. Also presented are complementary density and viscosity measurements by rotational viscometry at selected temperatures ranging from T = 16.00 to 28.00°C. For the application of the data to interpret microfluidic experiments, see Tanino et al. [1] and Christensen et al. [2].
