Calculate fluid specific gravity
(OP)
dear all
i was a question regarding fluid specific gravity
i was infrmed that Watercut is 30 % so oil is 70% and water is 30%,so i calculated specific garavity by :-
W.S.G= 0.3 * 1.016,AND o.s.g = 0.7 * 0.842 Then added them to get total fluid S.G ,,am i rigth ?.
also how i can calculate this fluid viscosity,centipoise.?
thanks in advance

RE: Calculate fluid specific gravity
Finding the viscosity of a mix of liquids is much more difficult. If you use the mole percent contribution of each of the species you will be ignoring interfacial reactions which can be larger than the friction component of parasitic pressure drop. The only reliable method I've found has been experimentation. Even experimentation is of limited value since small changes in fluid temperature make a big change in viscosity.

thanks for your answers,,i need the viscsty in drwing pump curves,,as i set it at one but i dont know real number

i have another question.in some wells ,wehn i start esp well operating with a sensor,the application engineer tells me the pump will start to produce oil at certian Pd,,,how can he figure certian Pi and Pd ,how he can know the limits of each
