Abstract
A drilling fluid composition is provided herein. The drilling fluid composition comprises biorenewable components, such as a polymerized biorenewable oil and at least one of biodiesel and a nonpolymerized biorenewable oil. The drilling fluid composition is thus more environmentally friendly than conventional, petroleum-based alternatives. Water-based and oil-based drilling fluids comprising the drilling fluid composition are also provided as are methods of lubricating a borehole (e.g., a downhole well) utilizing the drilling fluid composition.

A drilling fluid composition comprising a polymerized biorenewable oil, biodiesel and a nonpolymerized biorenewable oil.
2-3. (canceled)
(canceled)
9-10. (canceled)
(canceled)
A water-based drilling fluid comprising up to about 15 wt % of a drilling fluid composition comprising a polymerized biorenewable oil and at least one of biodiesel and a nonpolymerized biorenewable oil, wherein wt % is based upon the total weight of the water-based drilling fluid.
(canceled)
An oil-based drilling fluid comprising at least about 50 wt % of a drilling fluid additive comprising a polymerized biorenewable oil and at least one of biodiesel and a nonpolymerized biorenewable oil, wherein wt % is based upon the total weight of the oil-based drilling fluid.
A method of lubricating a borehole comprising:
- providing a drilling fluid composition comprising a polymerized biorenewable oil and at least one of biodiesel and a nonpolymerized biorenewable oil to a down hole well;
- and
- circulating the composition through the borehole.
