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 (20)

1. A method for producing a formulation to dispose in an oil well or add to oil sands to enhance recovery therefrom, 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. agitating said first reaction mixture; and

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

g. agitating said second reaction mixture so as to produce a formulation for recovering oil.

2. The method of claim 1 , wherein said reactor is a stainless steel reactor.

3. The method of claim 1 , wherein said reactor is a glass reactor with an added source of steel.

4. The method of claim 1 , wherein said reactor is a plastic reactor with an added source of steel.

5. The method of claim 1 , wherein agitating comprises stirring the mixture for at least 30 minutes at 1700-3500 rpm.

6. The method of claim 1 , wherein said reactor is grounded.

7. The method of claim 1 , wherein agitating comprises stirring the mixture until the solution is clear.
