Dear experts,
I would like to ask about Electrical Submersible Pump (ESP) operation in the offshore industry.
My understanding is described below.
The normal operation of ESP is that the pump will separate gas and liquid, then liquid will be pumped up through the tubing.
Gas will be separated into the casing and therefore a casing vent is required for this casing gas.
I was told that we have to keep the liquid level over the ESP by venting casing gas as much as possible (to lower the casing gas pressure) but I'm still not quite sure.
So, my question is
"Do we have to lower the casing gas as much as possible to enhance the ESP production? If so, what is the particular reason(s) for doing that?"
