Enhanced oil recovery (EOR) and improved oil recovery could (IOR) became more and more important due to the growing energy demand and depleting oil reserves. Recently, chemical EOR and IOR have drawn increasing interest due to the increase in oil prices and the scarcity of cheap oil reserves. Therefore, research on chemical EOR and IOR showed major growth in the recent years. When the formation is naturally tight, one can perform a stimulation technique by injecting acids and other chemicals through the wellbore and into the formation, which is called “acidization” or “well acid stimulation”.
In addition, the flow assurance (hydrate) and drilling fluid formulation are crucial areas that must be tackled in order to achieve the maximum gas and oil recovery using more economical, sustainable and environmental acceptable materials and methods. Development of polymeric materials for harsh operating and field conditions of the Gulf countries is another challenge. In the GPC, our ultimate goal is to acquire further knowledge in addressing different challenges.
The main challenges in the area of Enhanced Oil Recovery (EOR) are the high temperature high water salinity in the carbonate reservoirs in the Gulf region. In collaboration with a Akina leading company in USA, GPC is looking forward to develop new chemicals that can stand such harsh conditions should be introduced. The classical Polyacrylamide (PAM) may not be suitable for high salinity conditions. PAM copolymers or other polymers should be introduced.
The stability of these chemicals at high temperature should be examined. The main challenge in the Improved Oil Recovery (IOR) is to achieve proper utilization of water shut-off chemicals to boost oil/water production in oil fields. For acid stimulation, our target is the development of drag reducing agents for emulsified acids that is needed to provide stimulation to deeper reservoirs.
