Abstract
The present invention includes a cost effective custom-designed blend of organic chemicals to stimulate oil production. The invention includes a chemical composition for use in drilling operations for oil recovery and the method of using the chemical composition. The chemical composition includes an ammonia compound, an alcohol or polar organic compound, and aqueous carrier solution. The aqueous carrier solution is of sufficient volume such that it is operable to fully dissolve the ammonia compound and alcohol (or polar organic compound) in the aqueous carrier solution. Heating of the solution may be provide by encapsulated Polonium.
Claims17
A method of recovering hydrocarbons from a hydrocarbon formation containing hydrocarbon reserves, at least one injection well and one production well, the process comprising the steps of:
- a. injecting a chemical composition into the hydrocarbon formation in an amount effective to, when added to the formation, substantially increase the recovery of hydrocarbons from the reserves,
- wherein the chemical composition comprises a primary (methyl, ethyl or benzyl) amine compound, an alcohol and an aqueous carrier solution;
- said alcohol being selected from the group of butyl alcohol and phenol alcohol;
- and
- said aqueous carrier solution is a 50% to 75% aqueous solution having a divalent hardness contamination less than 50 ppm;
- b. heating said aqueous carrier solution in an annular flow across a tubular encapsulated Polonium thermal battery, said Polonium therermal battery having a first stabilize surface temperature between 300 F and 400 F;
- wherein said heating step transfers enough heat from said Polonium thermal battery to said aqueous carrier solution to make a 30 to 75 quality steam phase in said aqueous carrier solution;
- c. injecting said 30 to 75 quality steam phase aqueous carrier solution into the hydrocarbon formation containing the hydrocarbon reserves;
- and
- d. thereby producing hydrocarbons and aqueous carrier solution within at least one production well to recover the hydrocarbons from the formation.
