A METHOD FOR PROCESSING OIL WELL EMULSION INCLUDING, INTRODUCING A STREAM OF PETROLEUM INTO A FIRST CONFINED AND HEATED ZONE TO FURTHER THE RELEASE OF GAS AND FREE WATER FROM THE STREAM, PASSING THE LIQUID MIXTURE DOWNWARDLY AND THEN UPWARDLY TO UTILIZE THE FORCE OF GRAVITY AS AN ADDITIONAL FORCE TO RELEASE ADDITIONAL FREE WATER DEVELOPED IN THE MIXTURE, FURTHER HEATING THE LIQUID MIXTURE FROM THE FIRST CONFINED ZONE AS A FORCE APPLIED TO REDUCE THE VISCOSITY OF THE EMULSION AND BREAK THE EMULSION, AND RELEASE ADDITIONAL GAS FROM THE STREAM, PASSING THE LIQUIDS OVER A FIRST ELONGATED HORIZONTAL PATH TO RELEASE ADDITIONAL GAS FROM THE HEATED LIQUIDS, PASSING THE LIQUID MIXTURE DOWNWARDLY AGAIN AND THEN UPWARDLY TO UTILIZE THE FORCE OF GRAVITY TO RELEASE ADDITIONAL FREE WATER DEVELOPED IN THE MIXTURE, REMOVING THE FREE WATER RELEASE FROM BOTH CHANGES IN FLOW DIRECTION, AND FLOWING THE LIQUID MIXTURE INTO A SECOND CONFINED ZONE BETWEEN TWO ELECTRODES TO EXPOSE THE MIXTURE TO AN ELECTRICAL FORCE OF MAGNITUDE SUFFICIENT TO COALESCE THE WATER OF THE BROKEN EMULSION.
