Abstract

A composition and method for treating oil and gas drilling fluids containing organic contaminants comprising: a solidification agent, and a cell transport agent; wherein the composition comprises enough solidification agent to enable the solidification agent to electrolytically attract the organic contaminates to the surface of the solidification agent when hydrated.

Claims

1. A flowing powdered composition comprising:

a. an oil and gas drilling fluid cuttings containing organic contaminants;

b. 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 powdered free-flowing solidification agent;

c. a cell transport agent for combining with the powered free-flowing solidification agent and the organic contaminate of the oil and gas drilling fluid cuttings to form a free flowing absorptive metal citrate; and

 

wherein said composition comprises enough powdered free-flowing solidification agent to enable the powdered free-flowing solidification agent to electrolytically attract substantially all of the organic contaminates in the oil and gas drilling fluid cuttings 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 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

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 cell transport agent is a non-toxic acid.

11. The composition of claim 1, wherein the non-toxic organic acid cell-transport agent is a high molecular weight, naturally occurring acid.

12. 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.

13. The composition of claim 1, wherein said cell transport agent is an allomelanian derived acid.

14. The composition of claim 1, wherein said cell transport agent is a member of the group consisting of lactic acid, and combinations of lactic acid and citric acid.

15. 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.
