Chemical Flooding Laboratory

The field of chemical enhanced oil recovery (EOR) is gaining rapid interest in the petroleum industry. At Chemical Flooding lab located at the Department of Petroleum Engineering, Indian Institute of Technology (Indian School of Mines), we strive to extract just the additional quantity of tertiary oil trapped in petroleum hydrocarbon reserves by development of novel chemical EOR fluids. We hold technical expertise and intellectual resources to conduct detailed investigations; and describe a mechanistic approach to explain physicochemical processes occurring in oil-water-chemical fluid-rock systems.

A brief outline of a few major ongoing research initiatives:

Our laboratory is actively engaged in chemical EOR studies to achieve cost-effective oil recovery capability, which can be employed in pilot tests and real-field applications. Keeping this in mind, we are working towards multi-disciplinary areas of study involving surfactants, polymers, alkalis, nanoparticles, emulsions and foams.

Equipments Used in The Laboratory

Gas Hydrates Research Laboratory

---

---

Research Area: Gas Hydrates inhibition

---

This area involved the use of different inhibitors like glycols, amino- acids, and salts to reduce the formation of hydrates to ensure the flow assurance in pipelines. Detailed stability and kinetic studies are performed to observe the behavior of hydrates and maintain the temperature and pressure conditions out of the hydrate stability region to avoid their formation in pipelines.

---

Research Area: Gas Hydrates in drilling

---

Natural gas hydrates are presently considered as a potential source of future energy as it is widely distributed along the continental margins and in the permafrost areas. However, the drilling operation through such hydrate-bearing formation is quite risky because of unconsolidated formation, fragile nature of formation and uncontrolled dissociation of hydrate during drilling. Several studies are done to overcome the issues by a specially designed nanoparticle-enhanced water-based drilling fluid for its potential application in hydrate reservoirs.
