solids control

GN Solids Control company have sent a complete mud treatment system to Oman for a ZJ30 land drilling rig.

The ZJ30 mud cleaning system including the complete 4 stage solids control treatment:

1) 2 ea shale shaker model GNZS594

2) Desander separator 1 each

3) Desilter separator 1 each

4) Decanter centrifuge for barite recovery, 1 each, middle speed

For detailed parameters of the drilling mud system in Oman, you can visit GN website or contact with GN engineering group.

World leading centrifuge manufacturer – GN Solids Control launched its latest design decanter centrifuge with direct connecting motors.

Some customers showed great interest on it, and have question about the purpose of main drive motor and back drive motor in GN decanter centrifuge design. Blow we elaborate on this.

Main motor and back motor is powered for the centrifuge. It is the similar connection design with Derrick centrifuge. Main motor is connected directly with bowl. Back motor is connected with gearbox and then connect with centrifuge screw propeller.

High speed centrifuge is very important for mud purification. After some circulation, there will be more and more fine solids in the drilling mud, it will let the drilling mud too weight. In this case, high speed centrifuge is request to separate the fine solids in the drilling mud.

GNLW363 centrifuge is gear box type high speed centrifuge for fine solids separation. It has a 50hp main drive and a 15hp back drive, and use the gear box for differential speed.

For more information of GNLW363 centrifuge, you can visit GN website.

API RP 13 C set up the standard for the D100 cut point for the shale shaker screens

This helps the end user to identify the screens opening from different manufactuers.

Great disparity and performance in screens throughout the oil and gas drilling industry. But now With API RP 13C, API RP 13C is here. So you know exactly what you’re buying!

  • Two tests were devised: cut point and conductance. The tests describe a screen without predicting its performance and can be performed anywhere in the world.
  • After identifying the cut point and conductance, complying with API RP 13C requires application of a permanent tag or label to the screen in a position that will be both visible and legible. Both cut point expressed as an API number and conductance shown in kD/mm are required on the screen label.
  • Internationally, API RP 13C is ISO 13501 for screens
