Abstract
Methods and apparatus are provided for separation of liquids of different densities in production fluid streams from underground wells. Methods and apparatus are also provided for separation of gas, oil and water in production fluids, transportation of the separated fluids to the surface, as well as reinjection of separated water from the production fluids into other formations. Other aspects include new separation arrangements which include gas or liquid driven motors, designs for multi-stage hydrocyclone separators and use of beam or rod pumps.
