Additives for enhancement of oil flow

Abstract

Use of pyrolysis oil (commonly referred to as bio-oil, bio-crude or tire oil) in combination with naphtha or liquified petroleum gas (LPG) can be utilized to reduce viscosity, increase API gravity and/or liquify paraffin and/or asphaltene in heavy crude oil at a reduced, overall percentage of naphtha. Terpene, citrus isolates and/or non-ionic surfactants can be added to pyrolysis oil to form an additive. The additive can be combined with naphtha or LPG and added to heavy crude oil to reduce viscosity, increase API gravity, and/or liquify paraffin and/or asphaltene at a reduced, overall percentage of naphtha.

What is claimed is: 
     
         1 . A heavy crude oil additive comprising
 a naphtha; and   a pyrolysis oil.   
     
     
         2 . The heavy crude oil additive of  claim 1  further comprising at least one selected from the group comprising a terpene, one or more citrus isolates, and one or more non-ionic surfactants. 
     
     
         3 . A method of using the heavy crude oil additive of  claim 1  comprising adding the heavy crude oil additive to heavy crude oil to achieve at least one of the following: reduce the viscosity of the heavy crude oil, increase the API gravity of the heavy crude oil, or liquify a substance in the heavy crude oil. 
     
     
         4 . The method of  claim 3  wherein the substance is at least one selected from the group comprising paraffin and asphaltene. 
     
     
         5 . A method of preparing the composition of  claim 2  comprising
 adding at least one selected from the group comprising a terpene, one or more citrus isolates, and one or more non-ionic surfactants to a pyrolysis oil to form a first additive; 
 adding the first additive to a naphtha to form a second additive; and 
 adding the second additive to the heavy crude oil. 
 
     
     
         6 . The method of  claim 5  wherein the second additive is added to the heavy crude oil at between about 0.1 and about 20%. 
     
     
         7 . The method of  claim 6  wherein the second additive is added to the heavy crude oil at between about 2 and about 8%. 
     
     
         8 . The method of  claim 7  wherein the second additive is added to the heavy crude oil at about 4%. 
     
     
         9 . The composition of  claim 2  further comprising at least one selected from the group consisting of associated field gas, CO 2 , liquid natural gas, diesel fuels, fractional oils from pyrolysis oils, zeolite and electrolyzed/hydrolyzed clinoptilolite fragments, a taggant, iron nanoparticles, methane, ethane, propane, butane, kerosene, marine bunker fuels, and combinations thereof. 
     
     
         10 . The composition of  9  where the taggant is a Stokes shift taggant. 
     
     
         11 . A pyrolysis oil additive comprising
 at least one selected from the group comprising a terpene, one or more citrus isolates, and one or more non-ionic surfactants.   
     
     
         12 . A method of preparing the composition of  claim 11  comprising
 combining at least one selected from the group comprising a terpene, one or more citrus isolates, and one or more non-ionic surfactants. 
 
     
     
         13 . A heavy crude oil additive comprising
 liquified petroleum gas;   a pyrolysis oil; and   at least one selected from the group comprising a terpene, one or more citrus isolates, and one or more non-ionic surfactants.   
     
     
         14 . A method of using the heavy crude oil additive of  claim 13  comprising adding the heavy crude oil additive to heavy crude oil to achieve at least one of the following: reduce the viscosity of the heavy crude oil, increase the API gravity of the heavy crude oil, or liquify a substance in the heavy crude oil. 
     
     
         15 . The method of  claim 13  wherein the substance is at least one selected from the group comprising paraffin and asphaltene. 
     
     
         16 . A method of preparing the composition of  claim 13  comprising
 adding at least one selected from the group comprising a terpene, one or more citrus isolates, and one or more non-ionic surfactants to a pyrolysis oil to form a first additive; 
 adding the first additive to a liquified petroleum gas to form a second additive; and 
 adding the second additive to the heavy crude oil. 
 
     
     
         17 . The method of  claim 16  wherein the second additive is added to the heavy crude oil at between about 0.1 and about 20%. 
     
     
         18 . The method of  claim 17  wherein the second additive is added to the heavy crude oil at between about 2 and about 8%. 
     
     
         19 . The composition of  claim 18  further comprising with at least one selected from the group consisting of associated field gas, CO 2 , liquid natural gas, diesel fuels, fractional oils from pyrolysis oils, zeolite and electrolyzed/hydrolyzed clinoptilolite fragments, a taggant, iron nanoparticles, methane, ethane, propane, butane, kerosene, marine bunker fuels, and combinations thereof. 
     
     
         20 . The composition of  claim 19  wherein the taggant is a Stokes shift taggant.
