Abstract
Official abstract text for this publication.
Methods and processes for recycling base oils from spent invert emulsion drilling fluids may include frictionally heating a spent drilling fluid that comprises an invert emulsion and solids, wherein the solids are at about 50% or less by volume of the spent drilling fluid; and simultaneously evaporating oil and water from the invert emulsion at a temperature lower than an atmospheric boiling point for the oil.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: frictionally heating a spent drilling fluid that comprises an invert emulsion and solids, wherein the solids are at about 50% or less by volume of the spent drilling fluid; and simultaneously evaporating oil and water from the invert emulsion at a temperature lower than an atmospheric boiling point for the oil; collecting the oil; and producing a drilling fluid comprising the oil. 2. The method of claim 1 further comprising: collecting the water. 3. The method of claim 1 further comprising: collecting the solids; collecting the water; and mixing at least a portion of the water with at least a portion of the solids. 4. The method of claim 1 , wherein the solids are at about 30% or less by volume of the spent drilling fluid. 5. The method of claim 1 , wherein the solids are at about 10% or less by volume of the spent drilling fluid. 6. A method comprising: frictionally heating a spent drilling fluid that comprises an invert emulsion and solids, wherein the solids are at about 50% or less by volume of the spent drilling fluid; simultaneously evaporating oil and water of the invert emulsion at a temperature lower than an atmospheric boiling point for the oil; then, scrubbing the oil and the water having been evaporated from the spent drilling fluid; and then, separating the oil and the water. 7. The method of claim 6 further comprising: producing a drilling fluid comprising the oil. 8. The method of claim 6 further comprising: collecting the solids; and mixing at least a portion of the water with at least a portion of the solids. 9. The method of claim 6 , wherein the solids are at about 30% or less by volume of the spent drilling fluid. 10. The method of claim 6 , wherein the solids are at about 10% or less by volume of the spent drilling fluid. 11. A method comprising: frictionally heating a spent drilling fluid that comprises an invert emulsion and solids, wherein the solids are at about 50% or less by volume of the spent drilling fluid; simultaneously evaporating oil and water of the invert emulsion at a temperature lower than an atmospheric boiling point for the oil; separating the oil and the water; collecting the solids; and mixing at least a portion of the water with at least a portion of the solids. 12. The method of claim 11 further comprising: producing a drilling fluid comprising the oil. 13. The method of claim 11 , wherein the solids are at about 30% or less by volume of the spent drilling fluid. 14. The method of claim 11 , wherein the solids are at about 10% or less by volume of the spent drilling fluid.
