He does not believe that the technique can predict flow rates, even from rock that contains a lot of hydrocarbons-and flow rates are crucial to an oil field's economics.
Based on Empirical Mode Decomposition (EMD), a new method was presented to monitor flow pattern of oil-gas two-phase flow by using energy evaluation and threshold probability statistical technique.
基于经验模态分解技术，采用能量评估和阈值概率统计手段，提出了一种油气两相流流型状态监测的新方法。

Structures of the skin friction lines (SFL) appearing on a prolate spheroid in laminar and turbulent flows were investigated and compared by using an improved oil-flow visualization technique.
