Core annular flow of heavy crude oils in transportation pipelines and production wellbores |
| abstract |
A method is provided for enhancing the shear stability of a high-viscosity fluid-water flow system, such as a core annular flow system. The method employs a family of demulsifier additives for maintaining separation of the fluids in biphasic flow. The additive family is sodium salts of polynuclear aromatic sulfonic acids. In one aspect, the high-viscosity fluid is heavy oil. A method of transporting heavy oil through a tubular body is also provided. The method includes pumping the heavy oil through the tubular body within an annular flow of water, and subjecting the water in the tubular body to a salt of a polynuclear, aromatic sulfonic acid additive so as to improve shear stability of the heavy oil and water. |
