Drilling fluids and methods for making the same
A mixture suitable for use in a drilling fluid includes an amount base fluid and recycled fuel oil in an amount sufficient to provide an emulsion stability of the drilling fluid of about 500 volts or greater.
1. A mixture suitable for use in a drilling fluid comprising:
an amount of diesel base fluid; and
recycled fuel oil in an amount sufficient to provide an emulsion stability of a drilling fluid of about 500 volts or greater, the recycled fuel oil comprising recycled motor oil.
2. The mixture of claim 1 , wherein the mixture comprises up to about 50% recycled fuel oil.
3. The mixture of claim 1 , wherein the mixture of the base fluid and the recycled fuel oil form a portion of a virgin drilling fluid.
4. The mixture of claim 1 , wherein the mixture of the base fluid and the recycled fuel oil form a portion of a drilling fluid including recovered drilling fluid.
5. The mixture of claim 3 , wherein the virgin drilling fluid comprises a relaxed filtrate drilling fluid.
6. A drilling fluid comprising an amount of diesel base fluid and recycled fuel oil in an amount sufficient to provide an emulsion stability of about 500 volts or greater, the recycled fuel oil comprising recycled motor oil.
7. The drilling fluid of claim 6 , wherein a ratio between the amount of diesel base fluid and the amount of recycled fuel oil is up to about 1:1.
8. The drilling fluid of claim 6 , wherein the drilling fluid comprises virgin drilling fluid.
9. The drilling fluid of claim 6 , wherein a portion of the drilling fluid comprises recycled drilling fluid.
10. A method of forming a drilling fluid comprising:
mixing a selected amount of diesel base fluid with a selected amount of recycled fuel oil to form a mixture, the recycled fuel oil comprising recycled motor oil; and
mixing the mixture with other components to form a drilling fluid, the amount of recycled fuel oil selected to provide an emulsion stability of the drilling fluid of about 500 volts or greater.
11. The method of claim 10 , wherein mixing the mixture with other components to form a drilling fluid comprises mixing the mixture with other components to form a virgin drilling fluid.
12. The method of claim 10 , wherein mixing the mixture with other components to form a drilling fluid comprises mixing the mixture with recovered drilling fluid.
