Drilling fluids and processes for making drilling fluids for use in environmentally sensitive areas are provided. The environmentally friendly drilling fluid includes a linear olefin portion that includes linear alpha olefins and/or linear internal olefins with carbon numbers of about 6 carbons to about 30 carbons; and an oligomer portion comprising dimers, trimers, tetramers, and/or heavier oligomers of olefins, wherein the olefins have a carbon number of between about 4 carbons and about 24 carbons, and the oligomer portion includes at least about 50 mole percent of trisubstituted olefin. The drilling fluid has a pour point of about −10° C. or lower, a biodegradation ratio of about 1.0 or less, a toxicity ratio of about 1.0 or less, a Marine Bodis of at least about 60%, a flash point of about 110° C. or higher, a viscosity less than about 4 cSt at 40° C., a density of about 0.78 to about 0.83 gram/ml, and a log Pow of greater than about 3.
A drilling fluid comprising:
A drilling fluid suitable for use in environmentally sensitive areas, wherein the fluid passes pre-screening in accordance with OSPAR Recommendation 2000/4, as amended by OSPAR Recommendation 2008/1 and 2010/4, 2012-05, with a Marine Bodis of at least 60% as measured by OECD 301A, B, C, D or F and receives an OCNS grouping of either D, with a minimum aquatic toxicity of >100 and a minimum Sediment toxicity of >1,000, with no substitution warning, as listed on the Centre for Environment, Fisheries and Aquaculture Science (CEFAS) definitive ranked lists of registered products.
