Oil thinning 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 formulation comprising a first reaction product of a reaction mixture of one or more terpenoid compounds, soy methyl esters, and a first inorganic catalyst comprising copper in the presence of iron.
2. A composition comprising the reaction product of a reaction mixture of the formulation of claim 1 , one or more glycol ether esters and a second inorganic catalyst comprising copper in the presence of iron.
3. The formulation composition of claim 2 , wherein approximately 30-45 weight percent of said one or more terpenoid compounds, approximately 30-45 weight percent of said methyl esters, and about 20-30 weight percent of said glycol ether esters is used.
4. A formulation consisting essentially of the reaction product of a reaction mixture of one or more terpenoid compounds, soy methyl esters, and a first inorganic catalyst comprising copper in the presence of iron.
5. A composition comprising the reaction product of a reaction mixture of the formulation of claim 4 , one or more glycol ether esters and a second inorganic catalyst comprising copper in the presence of iron.
