- 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 consistent of: ground wood, ground corn, ground wheat, ground cotton, ground rice, ground hemp, ground sugar cane, pound nut shells, ground carboxy methyl cellulose, pulverized recycled paper, ground kenaf, and combinations thereof.
- 13. The composition of claim 1, wherein the cell transport agent is a non-toxic organic acid.
- 14. The composition of claim 13, wherein the non toxic organic acid is a high molecular weight, naturally occurring acid.
- 15. The composition of claim 1, wherein said cell transport agent is a member of the group, humic acid, fulvic acid, citric acid, fulvates, citrates, humates, lignins and combinations thereof.
- 16. The composition of claim 1, wherein said cell transport agent is an allomelanian derived acid.
- 17. The composition of claim 1, wherein said cell transport agent is a member of the group consisting of: lactic acid, citric acid and combinations thereof.
- 18. The composition of claim 1, wherein said cell transport agent is a member of the group consisting of lactic acid, citric acid, humic acid, fulvic acid, acetic acid, phosphoric acid, sulfuric acid, carbonic acid, nitric acid, and combinations thereof.
- 19. A method for treating drilling fluids with organic contaminates and drilling cuttings comprising the steps of:a. mixing the drilling fluids with organic contaminates and drilling cuttings in a high shear mixer; b. adding to the drilling fluids 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 which expands when hydrated and electrolytically attracts said organic contaminates to its surface; c. adding a cellulosic additive consisting of an oleophilic fibrous agent 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; d. adding a cell transport agent for combining with the powdered free-flowing solidification agent and the organic contaminants of the oil and gas drilling fluid cuttings in an amount between 0.5 wt % and 10 wt % based on the amount of said organic contaminate in the non-soluble drilling fluid, wherein said cell transport agent is capable of transporting large organic molecules through cell walls and neutralizing said mixture to a pH of between 7 and 8; and e. mixing at a high shear rate until said mixture forms a fine powder.
- 20. The method of claim 19 wherein said high shear rate mixing ranges from 5 minutes to 2 hours per batch.
