... friction factors are functions of Reynolds number and relative roughness of the walls. Churchill's (1977) equations are used to calculate the friction factors across the transition from laminar flow to turbulent flow. The representative Reynolds numbers in the impeller and diffuser respectively are (3...

... If the well is partially contributing from the wellbore, the well productivity is expected to be less than the productivity of the drilled length, and that will create a difference in calculation of the total dynamic head. The well productivity index, from well performance calculation...

... a well is waiting for an ALS to be installed for all wells in one calendar year. It is calculated by finding the difference between the end of one cycle for a well and the start of the next cycle for that same well. This non-productive time could be minimized by better planning for workovers and rig...

... platform have been introduced, for the platform, internet of things and wireless transmission technology are applied to achieve instantaneous interaction between mobile phone and server, cloud computing technology is applied to develop distributed calculation module, solving the problems of multi-user...
