Multiphase Pump
(OP)
Hey guys! Got a couple of questions regarding the BHP of a Pump.
We're trying to pump 700 BPD of heavy oil with a GVF of 95%. We want to calculate the power required for the pump. I know BHP=Q(GPM)*TDH(FT)*sp.gr/(3960*Eff(%)); my question is, do I use only the 700 bpd or the BPDe (BPD + GAS) of the mixture? Or do I just change the sp.gr. of the liquid to that of the mixture (gas + liquid).
Hope you can help me with this issue.
Thank you in advance!

Your driver must be prepared for 100% continuous slugs of full blown oil. Right?

MPP?
If you want to cover all bases, then yes 100% liquid at 700 bpd should be pretty bullet proof, but apart from cost and start current, there's not much else wrong about a motor only normally working at 20% of its power output.
either that or accept a trip every now and then.
What happens on start/stop is probably the most crucial. If the liquid can gather in one place or enter the pump in a much larger amount than during steady state conditions, then you should go for 100% of liquid.
