Recently GN solids control shipped one set of tandem shale shaker and mud cleaner to drilling company client. Shale shaker and mud cleaner is one of our major equipments among our production line, the other equipments produced by GN including:

Shaker screen, desander, desilter, vacuum degasser, decanter centrifuge, centrifugal pump, mixing hopper, mud agitator, mud gun, jet mud mixer, mud gas separator, vertical cuttings dryer, screw conveyor, screw pump, submersible slurry pump, oil sludge separation unit, drilling waste management system, solids control system, zero discharge system, cuttings solidification unit, mud recycling system, mud mixing system, dewatering unit, etc.

The tandem shale shaker is a combination unit of 2 unit of single shale shaker with tandem skid and common possum belly. Each single shaker with its own buffer box to make the mud flow to shaker screens evenly. The 3pcs or 4 pcs composite material frame shaker screens are installed on the shale shaker, with different mesh size, we can produce shaker screens comply with API RP13C standard and from API 20 to API 325, the user can use different API screens as per their requirement. During shipment, we need to make a special tandem skid transportation bracket for convenient container loading.
The mud cleaner is a 3 in 1 combination unit of desander cone, desilter cone and bottom shale shaker, the shaker screen size is same with tandem shale shaker screen size. The vibration motor is also interchangeable with shale shaker vibrator, the user can buy a extra vibration motor for back up in case of any damage of the vibrator, so as the bottom shaker spare parts. The client only need to make stock for the same model spare parts. The treating capacity is 1000gpm with 2 ea of 10 inch desander cone and 12 ea of 4 inch desilter cone.

Recently one unit of 200gpm mud recycling unit are ready for shipment for China HDD company, the technical configuration is as below:

1 unit of GNZS752F shale shaker as primary separation equipment. It is a 2 panel shale shaker normally used for mining solids removal unit, or small capacity HDD mud recycling system. The shaker screen is GN OEM composite material frame shaker screen.
1 unit of GNZS752F-6N mud cleaner as second phase cleaning equipment, it is a combination of desilter cone and bottom shaker.
1 unit of mud tank with desilter feeding pump, the shale shaker and mud cleaner installed on the mud tank. The system is for mud cleaning and storage only, if you need a mud mixing system, we can offer jet mud mixer, which is a combination of mixing hopper and mixing pump with pipelines.
Except for 200gpm mud recycling unit, we can also produce customized mud recycling system as per client’s requirement, for example, storage capacity, mixing capacity, . we can design and produce 400gpm, 500gpm, 600gpm, 800gpm, 1000gpm mud recycling system for different HDD machine, it can be applied for HDD, CBM, Geothermal drilling, water well drilling, pilings, TBM, micro tunneling, etc projects.

For some special projects, the normal mud recycling system can not meet the project requirement, decanter centrifuge can be used to separate the fine solids accumulated in the drilling fluids, so that the mud weight can meet the requirement of HDD drilling, the fluids can be reused to prepare for new drilling fluids. A middle speed decanter centrifuge is proper equipment, with separation cut point is 5 ~7 microns. After drilling, to meet environmental protection requirement, the decanter centrifuge with chemical dosing unit will be used to treat the drilling fluids, to get dry solids for easy transportation, and pure water for disposal, it can be also storaged for reuse.

Recently one set of workover drilling rig mud system are shipping to China drilling company. The technical configuration is as below:

1) Linear motion Shale shaker, since the workover rig operation do not need so much volume drilling fluids, one unit shale shaker treating capacity is enough , normally they will not use desander cone and desilter cone, which will need high power consumption centrifugal pump as feeding pump, only when it is required by the user, we will install the desander or desilter or mud cleaner.

2) Desander with its feeding pump, this is a desander unit without bottom shale shaker, the desander cone separation cut point is 45 microns, the desilter cone cut point is 25 microns. The centrifugal pump motor power could be 45 KW or 55 KW.
3) Mixing hopper and mixing pump worked as mixing unit of the mixing tank, to prepare for new drilling fluids which can be reused by the drilling rig.
4) Mixing pump
5) Mud agitator and mud gun, the coupling type mud agitator is required by the client, our standard model is direct connected type mud agitator, which the motor and gearbox is connected directly. The previous worm wheel type gearbox is no long used any more, the new type mud agitator are all helical type gearbox with reliable mixing performance.
6) Mud tank system, tank top is covered by galvanized steel grating for convenient watching the liquid level and for easy operation. The painting color could be customized as per client’s requirement. One tank is shaker tank with mixing unit, the other tank is reserve tank with only mud agitator and mud gun installed on it.
Except for mud tank system for workover rig, we can also design and produce mud recycling system for oil & gas drilling rig.
