Abstract: The disclosure relates to drilling fluid compositions, and their method of use, comprising a C16 unbranched internal olefin, including blends of the C16 unbranched internal olefin and a C16 linear alpha olefin. The exemplary drilling fluids are characterized by properties, e.g., pour points and kinematic viscosities, that enable them to be particularly useful in deep water drilling operations and have reduced environmental impact, e.g., increased biodegradation and reduced sediment toxicity.

Abstract: The disclosure relates to drilling fluid compositions, and their method of use, comprising a non-toxic and low cost-to-produce mineral base oil comprising 90 to 100% branched and cyclic-paraffins and virtually aromatic free. The disclosed base oils are suitable to replace diesel oil and distillates in any drilling operation and offers a reduced environmental impact and improved health and safety of employees.
