Oil timing compositions and retrieval methods
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.
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.
