Abstract
The invention deals with separating production fluids into separate components of oil, water, sand and gas in first and second stage separators. Preheating of the production fluid prior to entry into the first stage separator is partially accomplished by direct mixing with hot processed water taken from the effluent of the first stage separator and the second stage separator. Recirculated processed water may also be used to improve sand removal from the first and second stage separators.
