GN Solids Control has rich experience in making compact mud recycling system that used in no-dig drilling project. GN has standard model of compact mud system for option, for clients’ special requirements, GN is able to provide customized solution. This week, GN completed the fabrication of one set 350GPM mud recycling system for a UAE client.
The 350GPM mud recycling system in this order is GN standard self-contained unit with mud recycling, storage and mixing function. The equipment configuration is as below:

1. Shaker and mud cleaner composition unit- this unit is the main mud recycling equipment. The shaker equipped in this unit is a double deck model, the under layer is used as the first stage mud recycling equipment for coarse solids separation. GN composite frame shaker screen could effectively remove the solid particles; this process could reduce the load for the cyclone unit. The drilling mud passing through the under layer screen will immediately transferred by a centrifugal pump unit to the 4 inch cyclone for fine solids separation. The drilling mud after treated by the cyclone, solids with size larger than around 20 microns would be removed. Discharged slurry will be further dried by the upper layer screen for more fluids recovery.

2. A mud tank will be used as the mounting support of the shaker unit, the feeding pump of cyclone and the mixing pump would be mounted on the tank skid as well. On top of the tank, a mud hopper will be installed as the mud chemicals adding port. The mud tank is divided into two parts respectively for sand trap, storage and mixing.

This 350GPM mud recycling system could be packed in one 40 feed container for sea transportation. GN is full of experience in designing and manufacturing the compact mud recycling system. Besides the self-contained model, GN also has economic desanding unit that is widely used in piling project. For more information, please feel free to contact with GN.

Couple months before, GN delivered 3 units of poor boy degasser to GNPC. Today GN finished another order of poor boy degasser from a France Client. GN’s poor boy degasser is manufactured as per API and ISO standard for underbalanced condition drilling to prevent dramatic pressure surges. For most of the deep drilling rig, a poor boy degasser is indispensable equipment for safety operation consideration. 
On oil drilling site, the poor boy degasser is always located beside the mud recycling system. In normal condition, the dirty mud back from well will go directly to the drilling mud shale shaker for solids separation. Under this condition, the poor boy degasser will not be applied. In case gas layer was intruded, a blowout might happen. This is the when the poor boy degasser will be used.

GN’s poor boy degasser is with simple structure for gas cut mud hitting on the baffle plates for dispersion, and then the gas separated The degasser unit could be designed to fix on a skid, thus the poor boy could be folded and easily moved on site. The chock manifold can also be installed on the skid. Before the drilling mud getting into the poor boy degasser, the chock manifold will reduce the pressure of the mud firstly.
Mostly, the poor boy degasser will be connected with an ignition device. The flammable and poisonous gas discharged from the poor boy degasser will be guided to the ignition device for burning out. Safety should be give the priority forever in any jobsite. 
GN Solids Control is able to provide a one stop solution for all solids control equipment request, as well as the complete mud recycling system. If any request aroused, please feel free to contact with GN.

The closed loop system for treating the drilling waste is now more and more popular and requested by almost all the drilling plant and oil products producers. This week, GN completed the delivery inspection for some drilling waste management equipment including 2 vertical cuttings dryers and 4 decanter centrifuges. These equipment would be used by CNPC for their drilling waste treatment. 
Vertical cuttings dryer and decanter centrifuge are 2 of the main equipment in drilling waste management system. In the same system, cuttings dryer and centrifuge are installed in the same line but one after another in working procedure.

Vertical cuttings dryer is always used to treat the drilling waste cuttings discharged from the primary shale shaker in the solids control system. Discharged cuttings still has large content of drilling fluids that can be recovered for reuse. Besides the drilling cutting, most of the oily sludge treatment also use the cuttings dryer unit for large size solids separation. GN’s cuttings dryer is fixed with screen of 3 sizes. The finest is 250 microns, which means the solids larger than this size would be removed out. Please be noted, the solids less than 250 microns would pass through the screen opening and flow to next procedure with the liquid. After treated by GN vertical cuttings dryer, the OOC will be less than 5%. The effluence coming from the dryer unit needs to be polished by the centrifuge for ultrafine solids separation.

GN big bowl decanter centrifuge could be used in normal solids control system, waste management and some other separation projects. The centrifuge ordered by CNPC is the GN 18 inch model with big capacity and cut point is down to 2-5 microns. The adoption of duplex stainless steel and centrifugal casting technology guarantee the machine stable performance and fewer breaking down for maintenance. 
GN has established the business relation with many of the top class servicer and producer in oil industry. This is not the first time GN got order from CNPC, any request, please feel free to contact with GN.

GN just finished the fabrication of one batch of solids control equipment for a drilling company from Uzbekistan. The ordered equipment mainly includes shale shaker and vacuum degasser. Some drilling companies give the mud recycling service to a third party. However, to reduce the drilling cost, some drilling company will do the mud cleaning by themselves.

Shale shakeris the first stage solids control equipment; the performance of the shale shaker will greatly affect the performance of the complete mud system. The more coarse solids removed at the shale shaker stage, the better the mud system will perform. GN shale shaker has following advantages that ensure the onsite stable performance.

Firstly, the adjustable G force is up to 7.5 with excellent drying performance that will recover more drilling fluids. 
Secondly, the rubber seal installed between the shaker screen and screen support frame is patented. It is easy for installation and replacing. The imbedded rubber strip has good elasticity and chemical resistance for long time application in treating drilling fluids. This type sealing technology effectively avoids the leakage. 
Thirdly, all GN shale shakers have been upgraded to use the composite frameshaker screen that can last for longer time. It reduces the frequency of replacing the screen so that greatly save the cost.

GN vacuum degasser is a type degasser with self-suction function which means no need an extra feeding pump. It is located after the shale shaker to remove the gas in the drilling fluids. It has a long suction pipe inserting into the drilling fluids inside the tank, thus GN vacuum degasser could also be used as a big power mud agitator.

As a manufacturer of solids control and waste management equipment, GN Solids Control has the complete production line for fabrication the equipment from raw material of steel cuttings, bending, to lathe processing, then to coating process. At every procedure, GN adopts the up-dated fabrication machine to ensure the quality and efficiency. Recently, GN just upgraded the painting workshop appliances for purpose of both efficiency increasing and environmental protection.

Automatic shot blasting machine – shot blasting machine is used to working piece surface cleaning up and strengthen. It can remove the burr and rust of the casting, so that the subsequent painting process would be performed well.

Constant temperature spraying – In order to increase the paint coverage area on the working piece and outer surface painting quality, GN set up the dust-free and airless painting line. Airless painting machine applies high pressure on the paint, and then the paint was sprayed out via the spray gun as fog style. It can spray the paint to all points of the working piece where the brash will not reach. The thickness of the spray painting is uniform and the consumption is less. Constant temperature would speed up the drying process even in winter.

Electrostatic spraying – the material used in electrostatic spraying is the plastic powder. As the powder coating material has no solvent in it, it will not produce waste of water, gas and solid stuffs. Thus the electrostatic spraying technology is developed fast and nowadays widely applied. Electrostatic spraying also has advantages of high efficiency, suitable for automatic production line and coating powder recyclable.

With a series strict regulations issued on environment protection, many factories stopped their painting job. GN Solids Control is pleased to accept outsourcing painting service with precondition of completion of GN own painting job.

This week, GN’s fabrication department was busy finishing the final assembling of 2 sets containerized cuttings dryer systems for Russia client. Containerized design is especially for application in the low temperature area. Operators could work inside the container without bearing for the cold weather. Equipment could also be protected in warm place.
So far, GN has ever sent more than 10 units this type system to Russia. In the process of fabrication this kind of containerized cuttings drying system, GN accumulated lot of experience in equipment layout inside and what equipment will be needed to make the system works well.

 

Cuttings dryer is the main equipment in the system. The dryer is installed at one end of the container. At this part, the container is designed with open top cover. A hopper is connected with the feeding port of the cutting dryer for collecting the drilling cuttings. Beside the dryer unit, a cantilever crane is installed there for repairing purpose when lifting the upper part of the dryer.
Effluence discharged from the cutting dryer gravity flows into the collecting tank in the middle part of the container. On the tank, a mud agitator is installed for blending the fluids to prevent the solids from settling to the tank bottom.
A screw pump for feeding to decanter centrifuge is also installed inside the container for easy connecting with the collection tank. This tank is used to transfer the recovered drilling fluids from collection to tank to out connected decanter centrifuge for polishing. After treated by the decanter centrifuge, the drilling fluids could be reused.

 

For operators’ convenience, the container is also equipped with washing platform with clean water pipeline connecting port and cabinet for tools and small wear parts storage.
Now these 2 set containerized drilling cuttings treatment system are under the final assembling procedure, after that, all the equipment would be tested for trial running. GN has already contacted the shipping forwarder for preparation of delivery of the system. For more information on the system, please feel free to contact with GN.

 

Tunnel boring machine is an important machine in the city construction project like subway and pipe laying. In order to bring out the cutting and lubricate the drill bit of the tunneling machine, the operators need to add large quantity water or drilling fluids into the drilling well. For cost saving, the operators also have to think about reusing of the drilling fluids. Mud recycling equipment is mainly used to recycle the drilling fluids and remove the cuttings. Shale shaker, de-sander and de-silter could respectively separate the coarse solids, sand and silt. For fine solids, the decanter centrifuge would be needed.

After several time recycling, the specific gravity of the drilling fluids would be higher and higher due to the built up of ultrafine solids that even cannot be removed out by using only the centrifuge unit. Operators need to add chemicals into the drilling fluids and then do the dewatering process.  Dewatering centrifugepackage includes 2 parts: chemical dosing system and big bowl decanter centrifuge unit. The units ready for shipping to Singapore is designed containerized with both the centrifuge and dosing unit are put into the 20 feed container for easy transportation and jobsite safety purpose.

GN’sdosing system is consisting of powder feeding hopper, powder transferring screw, mixing tank and discharge pump. The screw is PLC for accurate metering of the powder. Mixing tank is divided into 3 departments for flocculation powder mixing, curing and storing. The mixing procedure is also PLC for automatic convenience. Before the drilling fluids fed into the decanter centrifuge, the flocculation agent is firstly mixed into the fluids to gather the ultrafine solids. Thus the decanter centrifuge would remove the floccule from the drilling fluids.

 

Removing the ultrafine solids from the drilling fluids greatly reduces the consumption of water and increase the drilling efficiency. The dewatering centrifuge package can also be used inoil sludge treatment project for oil recovery.
