A mobile apparatus and method for recycling an invert emulsion based drilling fluid, in which the invert emulsion based drilling fluid includes an oleaginous component and an aqueous component. The apparatus includes an emulsion breaking tank, a water treatment tank, a filter press, and hydrocarbon filters. The method includes: mixing said invert emulsion drilling fluid with a emulsion breaker, wherein the emulsion breaker is a mixture of an alkyl glucoside and an alkane sulfonate; and separating the oleaginous component of the invert emulsion drilling fluid from the aqueous component of the invert emulsion drilling fluid. The method preferably utilizes an emulsion breaker that is a combination of an anionic surfactant, a nonionic surfactant and an alkyl polyglycoside surfactant.

What is claimed is: 1. A mobile apparatus for recycling drilling mud or fluid, comprising: an emulsion breaking tank, which comprises an agitator, means for the addition of an emulsion breaker, means for the addition of drilling mud, means for removal of at least a portion of demulsified water, and means for recycling settled drilling mud or fluid back to a drilling process; a water treatment tank, which comprises an agitator, means for adding said at least portion of demulsified water, means for adding flocculation materials for producing a treatment water and a treatment sludge, means for removing the treatment sludge, and means for removing the treatment water, wherein said emulsion breaking tank is in fluid connection with said water treatment tank; a filter press for filtering said treatment sludge, wherein said water treatment tank is in fluid connection with said filter press; and, hydrocarbon filters for filtering said treatment water, wherein said water treatment tank is in fluid connection with said hydrocarbon filters. 2. The apparatus of claim 1, wherein the apparatus is mounted on a skid. 3. The apparatus of claim 2, wherein the apparatus is mounted on more than one skid. 4. The apparatus of claim 1 wherein the apparatus is sized to fit on a drilling rig. 5. The apparatus of claim 1, further comprising a second emulsion breaking tank. 6. The apparatus of claim 1, further comprising a pump to remove the drilling mud or fluid from said emulsion breaking tank. 7. The apparatus of claim 1 further comprising a tank which holds dehydrated mud from said filter press. 8. The apparatus of claim 1 wherein said hydrocarbon filters comprise a sack filters and cartridge filters. 9. The apparatus of claim 1 wherein the means for adding flocculation materials comprises a venturi powder doser. 10. The apparatus of claim 1 wherein the means for the addition of an emulsion breaker comprises a pump and a distribution system comprising multiple inlets. 11. The apparatus of claim 1 wherein the means for the addition of drilling mud comprises an inlet at the top of said emulsion breaking tank. 12. The apparatus of claim 1 wherein the means for removing said at least portion of said demulsified water comprises a means for skimming water from the top of said emulsion breaking tank. 13. The apparatus of claim 1 further comprising a waste mud pump on the bottom of said emulsion breaking tank. 14. The apparatus of claim 1 further comprising a filtrate return pump which recycles filtrate to said water treatment tank from said filter press. 15. The apparatus of claim 1, wherein said emulsion breaking tank and said water treatment tank comprise a conical bottom. 16. The apparatus of claim 1, wherein the emulsion breaker is a mixture of a non-ionic tensid and an anionic tensid. 17. A mobile apparatus for recycling drilling mud or fluid, comprising: an emulsion breaking vessel, means for the addition of an emulsion breaker, means for the addition of drilling mud or fluid, means for removal of at least a portion of demulsified water, and means for recycling settled drilling mud or fluid back to a drilling process; a water treatment tank which comprises an agitator, means for adding said at least portion of the demulsified water, means for adding flocculation materials for producing a treatment water and a treatment sludge, means for removing the treatment sludge, and means for removing the treatment water, wherein said emulsion breaking vessel is in fluid connection with said water treatment tank; a filter press for filtering the treatment sludge, wherein said water treatment tank is in fluid connection with said filter press; and, hydrocarbon filters for filtering the treatment water, wherein said water treatment tank is in fluid connection with said hydrocarbon filters. 18. The apparatus of claim 17, wherein said emulsion breaking vessel is a cyclone separator.
