The Petroleum and Natural Gas Engineering Department has the following laboratories for training and research as well as a machine shop.

1) Core Analysis and Sample Preparation: Porosity, permeability, electrical properties, fluid saturations, and the capillary pressure of rocks can be determined in this laboratory. Equipment for coring and extraction of reservoir rock samples are also available.

2) PVT: Fluid properties such as API gravity, viscosity, surface and interfacial tension, pH, refractive index, and vapor pressure analysis can be performed. Pressure, volume, and temperature relations of field hydrocarbons can be studied in this laboratory for graduate level research. Hydrocarbon properties such as bubble and dew point curves, critical temperature and pressure, and viscosity as a function of temperature or pressure are determined and flash vaporization analysis can be performed. Combustion and pyrolysis behavior of various hydrocarbons are investigated in this laboratory. Thermal and physical properties of petroleum , natural gas and products can be determined.

3) Drilling Fluid Testing Laboratory: Following experiments can be performed in the drilling laboratory: Evaluation of the yield points of the various bentonites, filtration properties, solids analysis, drilling fluid contamination and property changes, viscosity and rheological experiments. Finally, drilling fluid properties at elevated temperatures and pressures can be determined.

4) Enhanced Oil Recovery Laboratory: This laboratory is equipped with linear and three-dimensional fluid injection models for undergraduate and graduate level researches. Different techniques of steam injection, in-situ combustion reaction kinetics and microbial EOR can be investigated for heavy crude oils or oil shales. In addition, CO2 flooding, polymer injection, surfactant and micellar flooding fundamentals and applications to different crude oils in carbonate rocks are investigated.
