Method for making a road base material using treated oil and gas waste material
View Patent ↗The present invention provides a novel method to produce grade road base material using recycled oilfield waste, called “oil and gas waste,” more specifically, drilling waste and aggregate and a novel road base material. Hydration and mixing of the waste materials along with a binder, will achieve an irreversible pozzolanic chemical reaction necessary for stabilization into a road base. An asphalt emulsifier may be included in the binder to manufacture asphalt stabilized road base. The entire method is a cold batch process.
1. A method of creating a road base material comprising the steps of:
obtaining an oil and gas waste material;
obtaining an aggregate material;
removing a liquid component of the oil and gas waste material;
screening the oil and gas waste material;
screening the aggregate; and
mixing the aggregate and oil and gas waste, the mixing step including adding water and cement.
2. The method of claim 1 , wherein the oil and gas waste material includes waste material from a production site.
3. The method of claim 2 , further including the step of crushing the aggregate before screening the aggregate.
4. The method of claim 2 , further including the step of storing, after obtaining, the oil and gas waste material on an impervious layer.
5. The method of claim 2 , wherein the removing step includes removing oil and clean mud.
6. The method of claim 2 , wherein, after removing the liquid component containing some oil and some water, the oil and water is separated into an oil component and water component.
7. The method of claim 2 , wherein the removing step is accomplished by physical separation of some of the liquid base from the production waste material.
8. The method of claim 7 , wherein the mixing step is accomplished via batch mixing.
9. The method of claim 2 , wherein the screening of the production waste material includes shaking.
10. The method of claim 1 , wherein the oil and gas waste material includes drilling waste material.
11. The method of claim 10 , further including the step of crushing the aggregate before screening the aggregate.
12. The method of claim 10 , further including the step of storing, after obtaining, the oil and gas waste material on an impervious layer.
13. The method of claim 10 , wherein the removing step includes removing oil and clean mud.
14. The method of claim 10 , wherein, after removing the liquid component containing some oil and some water, the oil and water is separated into an oil component and water component.
15. The method of claim 10 , wherein the removing step is accomplished by physical separation of some of the liquid base from the production waste material.
16. The method of claim 15 , wherein the mixing step is accomplished via batch mixing.
17. The method of claim 10 , wherein the screening of the production waste material includes shaking.
18. The method of claim 1 , wherein the liquid component of the removing step is, in part, water and wherein said water is either injected into an injection or disposal well.
19. The method of claim 1 , wherein the liquid component of the removing step is, in part, water and wherein said water is treated for subsequent use.
