Abstract
Enhanced Oil Recovery (EOR), is a technique that has been used to recover the
remaining oil from the reservoirs after primary and secondary recovery methods. Some reservoirs
are very complex and require advanced EOR techniques that containing new materials
and additives in order to produce maximum oil in economic and environmentally friendly
manners. Because of EOR techniques, in this work previous and current challenges have
been discussed, and suggested some future opportunities. This work comprises the key factors,
such as; transport of Preformed Particle Gels (PPGs), Surface wettability and conformance
control that affect the efficiency of PPGs. The conduits, fractures, fracture-like features
and high permeability streaks are the big challenges for EOR, as they may cause early water
breakthrough and undesirable water channeling. Hence, the use of PPGs is one of the exclusive
commercial gel inventions, which not only increases the oil production but also decreases
the water cut during the oil production. Moreover, different studies regarding PPG, surfactants,
and Silica nanoparticle applications, such as the effect of salinity, particle size, swelling
ratio, gel strength, wettability, and adsorption were also discussed. Future work is required
in order to overcome the conformance problems and increase the oil recovery.
