Hexadecene Synthetic Drilling Fluid with Improved Environmental Properties

摘要

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.

主权项

1. A base fluid comprising a blend of:
a) a C16 unbranched internal olefin; and b) a C16 linear alpha olefin;wherein the base fluid has a pour point of 0° C. or lower, and wherein an amount of branched isomerized olefins in the base fluid is less than 10% of the combined volume of C16 unbranched internal olefin and the C16 linear alpha olefin.
