Downhole multi-parallel hydrocyclone separator

A process for separating a mixture, comprising:

• delivering the mixture to a separator assembly that comprises:
• a longitudinal housing configured for disposal in a wellbore, wherein the longitudinal housing comprises a discharge head disposed at one end of the longitudinal housing, wherein the discharge head includes at least one overflow port and at least one underflow port,
• a plurality of hydrocyclones disposed arranged in a same orientation in the longitudinal housing, wherein the plurality of hydrocyclone each comprise an overflow exit and an underflow exit, wherein at least two of the overflow exits of the plurality of hydrocyclones are connected to a common tubing that is connected to the at least one overflow port on the discharge head, wherein at least two of the underflow exits of the plurality of hydrocyclones are connected to separate tubings that are connected to the at least one underflow port on the discharge head;
• and
• separating the mixture in the separator assembly into an overflow component and a underflow component.
