...-to-ammonia system using statistical analysis. In an alkaline water electrolysis system, the purity of hydrogen was affected by the operating temperature and pressure of the hydrogen treatment system after the electrolysis reaction, where decreasing the operating temperature and increasing the operating...

... analysis oil technology reliability risk analysis statistical analysis Reserve estimation is an essential task in the development of an oil/gas field. The estimated reserves along with the forecasted production performance over time form the basis for the evaluation of a prospect’s economics...

... length variance downstream of the hilly terrain section. The statistical analysis shows mixed results of decreasing and increasing trends on mean slug lengths under the fluctuated separator pressure when compared with constant separator pressure conditions. The numerical simulation results showed a close...

..., probability distribution functions (PDF) determined from statistical analysis of “vertical” and “horizontal” AC signals are unique. For broad ranges of gas-liquid ratios, features extracted from the PDF are linearly related to gas and liquid flowrates. Contributed by the Petroleum Division and presented...
