Abstract
Disclosed is method of and product for enhanced oil recovery for a crude oil production well. The method includes the steps of pyrolyzing rubber materials including the steps of heating the rubber materials to form pyro-vapors, condensing the pyro-vapors to form pyro-gas and pyro-oil where the pyro-oil includes an inhibitor solution including non-polar hydrocarbons and polar hydrocarbons. The inhibitor solution is injected as an injection stream into the crude oil production well to facilitate production of crude oil from the crude oil production well.
Claims23
A method of enhanced oil recovery of crude oil from a production well comprising,
- pyrolyzing rubber materials including the steps of heating the rubber materials to form pyro-vapors, condensing the pyro-vapors to form pyro-gas and pyro-oil where the pyro-oil includes an inhibitor solution including non-polar hydrocarbons and polar hydrocarbons,
- mixing the inhibitor solution with crude oil to form an injection stream and injecting the injection stream into the production well to facilitate production of the crude oil from the production well.
A method of enhanced oil recovery of crude oil from a production well where the well has production impeded by paraffin comprising,
- pyrolyzing scrap tires including the steps of heating the scrap tires to greater than 800° C. to form pyro-vapors, condensing the pyro-vapors to form pyro-gas and pyro-oil where the pyro-oil includes an inhibitor solution formed of non-polar hydrocarbons and polar hydrocarbons wherein the non-polar hydrocarbons constitute at least 3% of the pyro-oil,
- mixing the inhibitor solution with crude oil to form an injection stream and injecting the injection stream into the production well to solubilize the paraffin to increase production of the crude oil from the production well.
A method of enhanced oil recovery of crude oil from a crude oil production well having an injector, piping, a core including an annulus, a pump and lift tubing where the core extends into a well bore to a crude oil reservoir for pumping crude oil having a viscosity increased by paraffin components comprising,
- pyrolyzing scrap tires including the steps of heating the scrap tires up to a Tmax temperature greater than 800° C. where the heating occurs over a period from 3 hours to 5 hours to form pyro-vapors, condensing the pyro-vapors to form pyro-gas and pyro-oil where the pyro-oil includes an inhibitor solution formed of non-polar hydrocarbons and polar hydrocarbons,
- mixing the inhibitor solution with the crude oil of the production well in a percentage greater than 0.15% to form an injection stream for lowering the Cloud Point temperature of paraffin in the crude oil of the production well,
- injecting the injection stream into a loop including the injector, the piping, the annulus, the pump and the lift tubing,
- providing a continuous flushing of the injection stream in the loop for solubilizing the paraffin to decrease the viscosity of the crude oil.
An inhibitor solution formed of non-polar hydrocarbons and polar hydro-carbons where the non-polar hydrocarbons include Benzoic acid;
- 1-Piperidinecarboxaldehyde and Caprolactam.
