ABSTRACT:
Disclosed is a low toxicity oil for use in drilling fluids. The oil consists essentially of branched- and cyclic-paraffins having 11 to 17 carbon atoms per molecule and further having a low aromatic content of less than about 1% and a low normal-paraffin content of less than about 5%. The low polynuclear aromatic oil is useful in both oil-based and water-based drilling mud, particularly where low toxicity and lack of water sheen are important such as in offshore drilling environments. The oil also has the advantage of being non-fluorescent so that it does not mask UV fluorescence of formation crudes produced from the drill cuttings in wildcatting operations.
