Abstract The gas lift method is an artificial of well production using the energy compressed injected into to reservoir fluid surface. formation paraffin deposits has remained one critical oil problems due growing percentage hard-to-recover reserves in overall structure. This complication also typical for many and fields Vietnam, such as White Tiger, Bear, Dragon fields. Wax deposit negatively ...

Introduction: Dust is continuously lifted from the Martian surface and put into atmospheric suspension. This is well visible during dust devil activity [1] and planet encircling dust storms [2]. The mechanism for the atmospheric dust entrainment has been debated for a long time. Wind stress can easily put dust into suspension under Earth conditions, i.e. at ~1000 mbar surface pressure. In princ...

The gas lift in the offshore M field will be performed with high CO2-content associated gas, but change of wellbore temperature and pressure during injection process lead to phase physical parameters which has a great impact on design lift. To ensure smooth implementation field, this paper conducts study considering CO2 state. We obtained density, viscosity, compression factor, constant specifi...
