Abstract
This invention relates to drilling fluids and processes for making drilling fluids, such as for use in environmentally sensitive areas. The environmentally friendly drilling fluid includes a first fluid component having between about 5 weight percent to about 95 weight percent of olefins with a chain length in a range of between about C12 and about C48. The first fluid component includes at least about 50 weight percent trisubstituted olefin functionality. The environmentally friendly drilling fluid includes a second fluid component.
Claims19
A drilling fluid suitable for use in environmentally sensitive areas, the fluid comprising:
- a linear portion comprising linear alpha olefins or linear internal olefins with carbon numbers of between about 6 carbons to about 30 carbons;
- and an oligomer portion comprising dimers, trimers, and heavier oligomers of molecules with carbon numbers of between about 4 carbons and about 12 carbons, the trimers and heavier oligomers comprise at least about 20 mole percent of the oligomer portion, the oligomer portion comprises at least about 50 mole percent of trisubstituted molecules;
- wherein the fluid has a pour point of about −20 degrees Celsius or lower, a biodegradation ratio of less than or equal to about 1.0, and a toxicity ratio of less than or equal to about 1.0.
