Poor boy degasser’s design purpose is for treating big volume of dissolved gas in the drilling mud. Such gas under the pressure will be expand if not take care it properly.  The poor boy degasser in traditional throttle pipe and between the vibrating screen and it has a direct discharge of gas pipeline. The installation of poor boy degasser is  typically installed in the rear of the throttle manifold.

The poor boy degasser needs meet the following operation needs:

  • Through field operation feedback, the capacity of gas process on poor boy degasser need to be five time as much as the design cycle.
  • The inner diameter of the pipeline need to be same or larger than the coke manifold in the inlet pipeline of the poor boy degasser.
  • The drilling fluid is directly discharged into the inlet manifold of the vibrating screen or the reserve tank of the drilling fluid.
  • The diameter of the exhaust should be 8 inches or greater.
  • The valve should not be installed on the gas discharge line.

Poor boy degasser parameters:

  • The gas from the separator must be firmly fixed.
  • During the cold weather the poor boy degasser installed on the bottom of the cleaning valve, in order to prevent liquid from blocking the liquid gas separator, the valve should be opened.
  • It need to be clean and maintain the poor boy degasser according to the specification or service provided by the manufacture

The choice making of use mud cleaner that contain desanders, desilters and shale shaker is concern of operation cost and the space allowed for the machinery.  It serves the purpose to remove the needed-remove solids in the drilling mud to keep the mud in high performance as needed. It is placed after shale shaker and vacuum degasser filtering the mud after initial filtering large solids and removes the gas that contain in the mud.

Turn the motor on and start pay attention on the rotation direction of the motor.  The motor need to be rotated in opposite directions and need to be marked on the motor direction after the confirmation of the check.  The operator at this stage need to pay attention on the sound that is from the machinery and if unusual sounds appear it needs turn off the machine and check the motors and tightness of the screens.

Operator need to perform routine check of motor bearing, the seals and lubrication of every moving part and fill the oils if necessary.  Such routine check need to perform after intense use of machinery to prevent structural damage that will most likely put the cleaning mud operation in stop.

To keep costs of operation in consist, shaker screen need to be flushed to clean the surface.  In some case of high viscosity of cleaning drilling mud, it also need to check the damage of the mesh as well after the flushing it with water.

Operator need to stop the feeding of the sand pump and let the shale shaker idle for period of times, rinse with water and timely clean the surface of the screen then stop the shale shaker motor.

Like the shaker screen, hydrocyclone is another replacement parts that need the cleaning like the screen after each shift of use.  This check to see if large objects are causing jamming that leads to shorted the use life of hydrocyclone.
