The use of pumping equipent to lift the fluids out of a well.
A technique used for increasing the productivity of wells with low reservoir pressure and/or heavy fluids (water, heavy oil) and enabling them to flow to surface either by introducing lighter weight fluid (gas) into the stream deep in the well or by providing a downhole pumping system (electrical or hydraulic submersible pumps - ESPs/HSPs).
