This week we shipped 1 unit of 350gpm mud cleaning system to UAE for HDD project. This is GN standard design of 350gpm mud recycling system, wit compact design, multi function, mixinig, cleaning, storage.

The technical configuration is as below:
A double deck shale shaker with 6ea of 4inch desilter cone, this is GN unique compact design to save the cost for the client, and make the complete mud system suitable for the limit area of the HDD contractor. The top layer of the double deck shale shaker as the mud cleaner to dry the separated solids , the bottom layer of the shale shaker as the coarse solids shale shaker, the 4 inch desilter cone is made of polyurethane material for abrasion resistance and longer service life.

If add 2ea of desilter cone on this system, it can be used as 500gpm mud recycling system by just changing the desilter feeding pump from 22kw to 37kw. The mud tank size and road transportation dimension are totally same.
Except for such compact design with cheaper price, we also provide customized design mud recycling system to meet the different requirement of our client. For example, for 350gpm, a separate 2 panel shale shaker with a 2 panel mud cleaner with 6 ea of 4” desilter cone.
The mixing hopper with mixing pump are installed on the mud tank to mix chemical additives with the bentonite.
For 500gpm mud recycling system, most of clients require the design of 1 ea shale shaker with 1 ea mud cleaner（ with bottom shale shaker, 1 ea desander cone, 8 ea of desilter cone, the composite material frame shaker screens are installed on the shale shaker, mud cleaner for longer working life and better performance, and it can be storage up to 5 years.
If you require HDD mud recycling system, pls contact with GN solids control.

This week GN shipped 3 units of mud gas separator to France, last week we shipped 3 units of same poor boy degasser to CNPC. The mud gas separator is also called poor boy degasser, it is applied to separate the hazardous gas from the gas cut drilling mud before feeding to the shale shaker, the primary equipments of the solids control equipments.

The mud gas separator is normally installed beside the solids control system, close the well head, the flare ignitor will be connected with the gas discharge pipe of the poor boy degasser, and fire the separated gas in the remote area.
The mud gas separator is skid mounted, installed with chock manifold, it is normally used for deep drilling rig or other drillings, like geothermal drilling, coal bed methane drilling, mining exploration, gas drilling, etc. The fluids discharge line is connected with the mud flow divider or called possem belly inlet, there is bypass valve so the mud can flow to shale shaker directly bypass the mud gas separator.
The mud gas separator can separate the hazardous gas like H2S from the gas cut drilling fluids to protect the shale shaker from damaged. The vacuum degasser or centrifugal degasser will be installed on the solids control system mud tank, it also separates the gas from the drilling fluids to keep the drilling mud balance and protect the centrifugal pump.
The basic solids control system including shale shaker, desander, desilter, feeding pump, vacuum degasser, decanter centrifuge, mud tank, pill tank, trip tank with trip pump, reserve tank, mud mixing unit, etc. For customized solution of mud pit and solids control equipments, pls contact with GN solids control.
We also provide complete solution for drilling waste management system as a zero discharge system, the recycled mud can be reused by the drilling rig, the cuttings can reach the limit of landfill or send them to further process of TDU.

This week GN Start the production of cuttings solidification unit for CNPC, Last week we shipped the vertical cuttings dryer and decanter centrifuge to CNPC for their drilling waste management project. The cuttings solidification unit is also an equipment to treat the final drilling cuttings when you do not need to reused the drilling mud.

The configuration of the cuttings solidification unit for CNPC, including:
1 Cuttings collection: The cuttings collection system including a hopper with a screw conveyor, The drilling cuttings from solids control system and drilling waste management system will be collected by the hopper and transferred by the screw conveyor to the mixing vessel.
2 Chemical storage：One of them are used to storage the curing agent, one is used to storage the desiccant, the screw conveyor equipped on the tank will transfer the chemicals to the mixing vessel automatically.

Recently we shipped 2 vertical cuttings dryer and 4 decanter centrifuges to CNPC, these drilling waste management equipments are used widely in the world for drilling cuttings treatment projects. Since 2015, Chinese government has issued very st

rict environmental protection laws for the drilling waste treatment, all of the new drillings rigs must equipped with zero discharge drilling waste management system, including solids control system to recycle most of the drilling fluids to be used by the drilling rig, also include the vertical cuttings dryer system to recycle the useful drilling fluids and to reduce the oil content in the discharged solids below 5%, which can match the government required limit.

The vertical cuttings dryer and decanter centrifuge are the major equipments for the drilling waste management system, the working process is as below:

The cuttings collection system( vacuum pump, screw conveyor, etc. equipments) to transfer the drilling waste to the vertical cuttings dryer inlet port on the top, the solids discharged from vertical cuttings dryer with OOC below 5%, the fluids will flow to the intermediate tank, the screw pump will pump the fluids to the decanter centrifuge to separate fine solids from the fluids, because the normal screen opening of the screen basket of the vertical cuttings dryer is 0.35mm, 0.5mm, most of the fine solids still remained in the fluids, it can not reach the standard to be reused.
The decanter centrifuge can be used for both barite recovery, low gravity solids separation, high gravity solids separation and drilling waste management system.
GN has established the supplier relationship with many big oil companies or oil service companies in the world, especially for the government owned company. If you want to work as representative of GN solids control or require decanter centrifuge, vertical cuttings dryer, pls contact with our sales.
