PHASE SEPARATION OF TWO-PHASE FLUID IN AN EOR INJECTION WELLBORE

Two phase flow occurs when two phases flow simultaneously in pipes. The fluid
may tend to separate because of differences in densities and flow velocities in the
pipe. (Dale Beggs, 2003). In this project, flow of a gas-liquid fluid in the injection
wellbore is studied. The gas water mixture are injected into multiple perforations or
producing zones.
As the two phases have different density, separation of the two phases is likely to
occur. We are concern of the phase separation that will occur as this will affect the
injection efficiency. Degree of the separation and the factors contributing to the
separation will be investigated.
Parameters that are going to be determined are flow pattern, liquid holdup and
pressure drop. Different flow patterns give different results and play the most
important role in this study. For that reason, flow patterns prediction has been an
important aspect in this study.
Computer simulation will be conducted using Mathematica software. The calculation
procedure will be coded into the software and a set of data will be used for the
simulations
