The secondary recovery and EOR techniques have become a vital part
of petroleum production to meet the ever-increasing demand for raw
materials. There are many different injecting fluid types and properties which
can be tinkered into specific scenarios. This research report will cover the
effects of injecting fluid types on recovery rate and ultimate recovery factor
under laboratory conditions. The main focus will be on the immiscible
displacement of oil in porous media under
the effects of gravity and
capillary(imbibition) forces.
The fundamental goal of this research paper is to demonstrate the
relationship between the injecting fluid and the ultimate reservoir production.
For that purpose, firstly, different parameters affecting the recovery process
were found through laboratory experiments. The mentioned experiments
utilized the varying fluid types to alter key properties such as interfacial
tension between phases and viscosities to adjust
the mobility ratio to
replicate the immiscible displacement of oil in the porous media. Then, these
fluids were used in conjunction with core samples of very similar shape and
size to prevent possible errors. During tests, recovery profiles for each
combination were recorded and analyzed.
Follow-up simulation studies will
be conducted on the common
numerical model for different reservoirs to verify the results of laboratory
experiments and papers.
