Claims
- 1. A flowing powdered composition for waste oil and gas drilling fluids containing organic contaminants and drilling cuttings comprising:a. a powered free-flowing solidification agent adapted for highly charged absorption and adapted to enable the organic contaminates in the waste oil and gas drilling fluid to adhere to the molecular surface of the powdered free-flowing solidification agent; cellulosic additive consisting of oleophilic fibrous agent forming a mixture; and wherein said mixture comprises enough powdered free-flowing solidification agent to enable the powdered free-flowing solidification agent to electrolytically attract the organic contaminates to the surface of the powdered free-flowing solidification agent when hydrated.
- 2. The composition of claim 1, wherein said fluid cuttings comprise drilling process fluids and drilling completion fluids.
- 3. The composition of claim 2, wherein said drilling process fluids and drilling completion fluids are drilling muds.
- 4. The composition of claim 1, wherein said solidification agent is a member of the group; alkaline earth metal oxide, alkaline earth metal hydroxide, a high lime based ash, a Portland cement, and combinations thereof.
- 5. The composition of claim 1 wherein said solidification agent is a member of the group consisting of magnesium oxide, magnesium peroxide, magnesium hydroxide, magnesium silicate, calcium oxide, calcium peroxide, calcium hydroxide, calcium silicate, and combinations thereof.
- 6. The composition of claim 1, wherein said solidification agent is a member of the group consisting of magnesium hydride, magnesium borate, magnesium nitrate, magnesium phosphate, magnesium sulfate, calcium hydride, calcium borate, calcium nitrate, calcium phosphate, calcium carbonate, calcium sulfate, and combinations thereof.
- 7. The composition according to claim 1, wherein said solidification agent is a member of the group:a. potassium oxide, potassium peroxide, potassium hydroxide, potassium hydride, potassium borate, potassium nitrate, potassium phosphate, potassium silicate, potassium sulfate; b. cesium hydroxide, cesium carbonate, cesium sulfate; c. sodium oxide, sodium peroxide, sodium hydroxide, sodium hydride, sodium borate, sodium nitrate, sodium phosphate, sodium silicate, sodium sulfate; d. lithium oxide, lithium hydroxide, lithium borohydride; and any combinations thereof.
- 8. The composition of claim 1, wherein the solidification agent is present in said composition in an amount up to 99 wt. % of the composition.
- 9. The composition of claim 1, wherein said solidification agent is hydrophobized.
- 10. The composition of claim 1, wherein the cellulosic additive is kenaf.
- 11. The composition of claim 1, wherein the cellulosic additive is present in said composition in an amount up to 50 wt % of the composition.
- 12. The composition of claim 1, wherein said cellulosic additive is a member of the group consisting of ground wood, ground corn, ground wheat, ground cotton, ground rice, ground hemp, ground sugar cane, ground nut shells, ground carboxy methyl cellulose, pulverized recycled paper, ground kenaf, and combinations thereof.
- 13. A method for treating waste drilling fluids with organic contaminates and drilling cuttings comprising the steps of:a. mixing the waste drilling fluids with organic contaminates and drilling cuttings in a high shear mixer; b. adding a powdered free flowing solidification agent adapted for highly charged absorption and adapted to enable the organic contaminates to adhere to the molecular surface of the powered free flowing solidification agent; and to expand when hydrated and electrolytically attracts said organic contaminates to its surface; c. adding a cellulosic additive consisting of an oleophilic fibrous agent forming a mixture in an amount between 1 and 50 wt % based on the amount of said organic contaminate in the drilling fluid forming a mixture of free flowing absorptive metal citrate; and d. mixing at a high shear rate until said mixture forms a fine powder.
- 14. The method of claim 13 wherein said high shear rate mixing ranges from 5 minutes to 2 hours per batch.
- 15. The method of claim 14, wherein said high shear rate mixing is performed from between 10 minutes and 1 hour.
- 16. The method of claim 13, wherein said mixing is performed at a temperature between 210° F. and 500° F.
- 17. The method of claim 13, wherein said mixing is a continuous mixing process that occurs at a rate of between 30 and 40 MT per hour.
