Measurement of Gas Viscosity at High Pressures and High Temperatures

Gas viscosity is an important fluid property in petroleum engineering due to its impact in oil and gas production<br>and transportation where it contributes to the resistance to the flow of a fluid both in porous media and pipes.<br>Although the property has been studied thoroughly at low to intermediate pressures and temperatures, there is<br>lack of detailed knowledge of gas viscosity behavior at high pressures and high temperatures (HPHT) in the oil<br>and gas industry.
