Gas separator

Abstract

A combination liquid and gas separator and jetting tool includes a housing containing a rotatable drum, a stator in the inlet end of the housing for swirling a liquid/gas mixture, a rotor attached to the drum for rotation by the mixture; whereby the gas and liquid are separated. The liquid and gas are discharged through separate restricted orifices downstream of the drum. Orifices can be located in a rotating head for cleaning, cutting or other downhole operations.

1 . A method of jetting comprising the steps of:
 passing a two-phase fluid stream through a jetting tool; and   removing gas from the two-phase fluid stream thereby producing a gas-rich phase and a liquid phase containing less than 1 vol % gas.   
   
   
       2 . The method according to  claim 1  wherein the gas-rich phase and the liquid phase are discharged from the tool and the gas-rich phase shrouds the discharge of the liquid phase. 
   
   
       3 . A method comprising:
 pumping a two phase fluid containing a gas and a liquid into a wellbore; and   separating the gas phase from the liquid phase whereby the resulting liquid phase contains less than 1 vol % gas.
