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.
Claims18
A drilling fluid composition comprising a polymerized biorenewable oil, biodiesel and a nonpolymerized biorenewable oil, wherein the ratio of biodiesel to polymerized biorenewable oil is from 10:1 to 1:10 and the ratio of nonpolymerized biorenewable oil to polymerized biorenewable oil is from 10:1 to 1:10.
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, and wherein the drilling fluid composition comprises biodiesel or a nonpolymerized biorenewable oil and a polymerized biorenewable oil in a ratio of biodiesel or nonpolymerized biorenewable oil:polymerized biorenewable oil of from 10:1 to 1:10.
An oil-based drilling fluid comprising at least about 50 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 oil-based drilling fluid, and wherein the drilling fluid composition comprises biodiesel or a nonpolymerized biorenewable oil and a polymerized biorenewable oil in a ratio of biodiesel or nonpolymerized biorenewable oil:polymerized biorenewable oil of from 10:1 to 1:10.
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 borehole;
- and
- circulating the composition through the borehole;
- wherein the drilling fluid composition comprises biodiesel or a nonpolymerized biorenewable oil and a polymerized biorenewable oil in a ratio of biodiesel or nonpolymerized biorenewable oil:polymerized biorenewable oil of from 10:1 to 1:10.
