Abstract
Apparatus and method for pumping fluids from horizontal wells with a dip tube used without requiring a packer in the well. Gas is separated from the liquid phase ahead of the pump to avoid slug flow of gas into the pump. This increases the amount of oil that can be pumped from the well by avoiding shutdowns resulting from gas-locking of the pump.
