1. A composition for oil and gas drilling fluids containing organic contaminants comprising:
- a. a solidification agent;
b. cell transport agent;
c. a cellulosic additive; and
wherein said 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.

19. A method for treating drilling fluids with organic contaminates comprising the steps of:
-
a. mixing the drilling fluids with organic contaminates in a high shear mixer;
b. adding a solidification agent which expands when hydrated and electrolytically attracts said organic contaminates to its surface;
c. adding a cellulosic additive in an amount between 1 and 50 wt % based on the amount of said organic contaminate in the drilling fluid forming a mixture;
d. adding a cell transport agent 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.
