A CFD study of steam injection tubing heat losses

Abstract

To increase heavy oil production, the petroleum industry uses thermal recovery methods, with steam injection being one of the most common techniques. A three-dimensional simulation of the multiphase, turbulent liquid-vapor flow along a 100 m wellbore is presented, composed of injection tubing, annular space, casing, and rock formation. The performance of insulated and non-insulated tubing is evaluated, with 80% quality steam at two different flow rates. The insulated material tubing (IMT) showed better performance, reducing heat loss and maintaining higher steam quality at the well output.
