Abstract

The present invention relates to compositions of plant oil-based biodegradable crude oil thinning fluids having a performance especially suitable to reducing crude oil viscosity in extraction and retrieval operations.

Claims (38)

1. A method of producing a formulation, wherein said formulation is prepared by a method comprising:

a) providing

i) a solution of one or more terpenoid compounds,

ii) soy methyl esters,

iii) glycol ether esters,

iv) a first inorganic catalyst,

v) a second inorganic catalyst, and

vi) a reactor;

b) placing said solution of one or more terpenoid compounds in said reactor,

c) suspending said first inorganic catalyst in said solution in said reactor;

d) adding said soy methyl esters to the reactor to create a first reaction mixture;

e) reacting said first reaction mixture with said first inorganic catalyst by agitation;

f) adding said glycol ether esters to said first reaction mixture in the presence of said second inorganic catalyst to create a second reaction mixture;

g) reacting said second reaction mixture with said second inorganic catalyst; and

h) separating said first and second inorganic catalyst from the resulting mixture so as to produce a formulation.

2. The formulation produced according to claim 1 .

3. A method to improve oil flow from an oil pipe, comprising:

a) providing the formulation according to claim 2 ;

b) introducing a first portion of said formulation into said oil pipe;

c) obtaining a mixture from said oil pipe, said mixture comprising at least a portion of said formulation and oil from said oil pipe; and

d) recovering said formulation from said mixture obtained from said oil pipe.

4. The method of claim 3 , wherein said oil pipe comprises an oil field pipe.

5. The method of claim 3 , wherein said formulation is added to oil pipe in order to clear a blockage.

6. The method of claim 5 , wherein said blockage comprises a paraffin plug.

7. The method of claim 5 , wherein said mixture treats an existing paraffin plug within said oil pipe.

8. The method of claim 3 , wherein said oil pipe is buried pipes.

9. The method of claim 3 , wherein said oil pipe is exposed to extreme temperatures.

10. The method of claim 9 , wherein said extreme temperature is −60° C.

11. The method of claim 9 , wherein said extreme temperature is 40° C.

12. The method of claim 3 , wherein said formulation is added to said oil pipe to enable the recovery of otherwise uncapturable oil.

13. The method of claim 3 , wherein said one or more terpenoid compounds comprises D-limonene.

14. The method of claim 3 , wherein said formulation comprises approximately 30-45 weight percent of said terpenoid compounds, approximately 30-45 weight percent of said soy methyl esters, and the balance of weight percent of said glycol ether esters.

15. The method of claim 3 , wherein said formulation comprises about 20-30 weight percent of said glycol ether esters.

16. The method of claim 9 , wherein said extreme temperature range comprises −60° C. to 40° C.

17. The method of claim 3 , wherein said formulation is at least 80% recoverable.

18. The method of claim 3 , wherein said formulation is at least 90% recoverable.

19. The method of claim 3 , wherein said recovering comprises separation of the formulation from the oil from the mixture obtained from said oil pipe.

20. The method of claim 3 , wherein the method further comprises e) reusing said recovered formulation to improve oil flow from an oil pipe.
