The separator is placed above the Motor or Jetting Tool and separates the gas from liquid phases in a nitrified fluid. This reduces the volume of gas passing through the BHA preventing damage to motors and increasing the impingement force of jets while maintaining an underbalanced condition in the annulus.

A single Separator Stem and housing composes the separating section in which the fluid phase is forced to the internal walls of the housing as a result of its density and the centrifugal forces acting upon it.

The gas is then allowed to remain in the center where it is vented through the center of the Separator Stem. Fluid continues its path through the BHA and the gas moves upwards and into the annulus via side ports located above the separating section.

Features and Benefits:

- Enhance equipment reliability and performance, particularly with PDM’s, by minimizing the amount of gas that passes through the motor thus minimizing damage to the stator and reducing downtime, which in turn and maximizes operational time and minimizes cost.

- Control downhole gas flow by either venting into the annular space or through the BHA as required depending on the volume and rate of gas being injected at surface.

- Minimize formation damage by allowing operations to be carried out in live wells without compromising safety, resulting in improved productivity.

- Simplify surface equipment requirements by removing the need for a parasitic string resulting in faster rig up times and lower cost.

- Ensure faster drilling/milling operations by maximizing fluid volumes reach the motor increasing efficiency and power delivery.

- Remove the need to retrieve and change BHA configuration once gas is not required as GMASS® can work with single fluids or multiphase fluids.
