• Gas or electricity can greatly reduce climate impact of vehicles compared to diesel. WTW performance depends on the energy sources. Climate vehicle gas decreases linearly more biomethane it contains. perspective give lower than TTW perspective. For electricity, is always higher impact. Focusing tailpipe emissions, current EU policies do not favor use biofuels in transports. This paper analyze...

The accurate forecast of wellbore temperature and pressure during intervention operations is critical to the long-term exploitation deep-water oil gas resources. A prediction model was constructed in seawater formation sections based on Hasan Kerber’s gas-liquid two-phase flow heat transfer integrated with features operations. Simultaneously, exchange produced by change fluid rate caused tool p...
