Drilling waste management system contains several equipment and tank to make a full solution including vertical cuttings dryer for dry drilling cuttings , decanter centrifuge to recycle drilling fluids out of vertical cuttings dryer , screw pump for feed decanter centrifuge and flush outlet of vertical cuttings dryer , air compressor to supply air for air knife on vertical cuttings dryer , screw conveyor to transfer drilling cuttings , mud tank and work plat form to make all process continuously .

Vertical cuttings dryer is one of the core equipment and will dry drilling cuttings with fluids content bellow 5 percent at 900 RPM rotating speed tank body . The screen can be use 0.25 to 0.5 mm size depending on requirement , one set of air knife will be needed to match vertical cuttings dryer which is powered by one set of air compressor . One set of screw pump will be needed to flush outlet fluids to keep sure fluids will be flow out when high viscosity and density . There will need minimum 2 sets of screw auger to feed drilling cuttings into vertical cuttings dryer , one set horizontal to collect drilling cuttings from shale shaker , desander and desilter , another one to feed drilling cuttings to vertical cuttings dryer .

One set high speed decanter centrifuge to recycle drilling fluids that recycled by vertical cuttings dryer at 2 to 5 microns separate at 3200 RPM bowl speed . one set of VFD control panels is optional , the VFD control panel will change speed of centrifuge bowl from 0 to 3200 RPM but quite big size . If you want small footprint , then you can choose one set of fixed speed decanter centrifuge .

Other than the vertical cuttings dryer and decanter centrifuge , there will be other equipment to cooperate like screw pump , tank , work form , etc .

Containerized drilling waste management system normally will be used in Russia for lower temperature and winterized conditions . GN Solids Control delivery the third sets of containerized drilling waste management to the same client last week and get a good feed back of drilling waste management equipment performance in Russia . The main equipment will including vertical cuttings dryer , decanter centrifuge , screw conveyor , screw pump , 40 feet container and work skid .

40 feet container supplied to keep vertical cuttings dryer and other drilling waste management equipment inside for winterization design . We made some changes on the container like doors or windle depending on working requirement . The whole container size on a big work platform to hold all above and make a base for the cover and temperature issues .

One set vertical cuttings dryer with 930mm size diameter tank and 900 RPM rotating speed to allow drilling cuttings treating flow reaches to 30 to 50 cubic meters per hour . the dry solids treated by vertical cuttings dryer will reduce fluids and fluids content will be bellow 5 percent totally . One set screw pump will be installed to flush vertical cuttings dryer incase fluids content a lot of fine solids and make it hard to flow . The air knife will make client need a air compressior and this design is for avoid screen block by water base drilling cuttings .

One set of decanter centrifuge will be installed to recycling drilling mud that recycled by vertical cuttings dryer . It is high speed centrifuge with 3200 RPM rotating speed for separation 2 to 5 microns solids out and 30 cubic meters per hour drilling mud flow max . The tungsten carbide tiles is bolted on screw impeller to help screw working longer life .

Linear motion shale shaker is the most popular design of shale shaker for oil and gas industry and steady working performance . GN Solids bring one set of linear motion shale shaker to Indonesia for show and delivery it back after the show . There are many supplier that related with drilling appear in the show with good feedback of show . GN Solids shale shaker attract eyes of the visitors cause seldom solids control supplier bring a equipment to show .

There are 3 options for GN shale shaker , GNZS703 , GNZS594 and GNZS752 for 4 decks , 3 decks and 2 decks . Client can choose to suitable model depending on there drilling conditions and mud flow requirement . The 2 decks shale shaker normally working for horizontal directional drilling , and small coal gas methan drilling rigs . 3 decks and 4 decks shale shaker can be use for oil and gas drilling , coal gas methan drilling and gethormal drilling , etc . The 4 decks shaker can be used for drilling waste management also cause the longer deck help dryer drilling cuttings better . Both GNZS703 and GNZS594 shaker deck can adjust deck angle from -1 to 5 degree depending on drilling mud conditions and GNZS752 shaker fixed +2 degree .

Other than shale shaker , if install different design of cyclone will change shale shaker to be desander , desilter or mud cleaner . The GNZS752 shaker normally for desander or desilter only cause screen area not big enough but GNZS703 and GNZS594 shaker can be make desander , desilter separated or a mud cleaner for a three in one cause larger screen area . After the desander and desilter , GN Solids can supply a decanter centrifuge for forth phase cleaning to 2 – 5 microns fine solids . Please contact GN office if any inquiry .

Linear motion shale shaker is the most popular motion shale shaker in the world cause it’s steady work and good performance . GN Solids Control just delivery 4 sets of shale shaker to an UAE drilling contractor for oil and gas drilling industry . Linear motion shale shaker is made by 2 sets of vibrator motor that rotating by opposite direction to make shale shaker linear motion vibrating .

GN Solids has different size of linear motion with 2 decks , 3 decks , 4 decks for different treating capacity and different application . The decks shale shaker will be working for horizontal drilling and small mud flow required drilling mud recycling system . The four decks of shale shaker will be working for oilfield solids control system and or drilling waste management system for water base drilling cuttings process . The UAE drilling contractor purchased 3 deck shale shaker with wedge type shaker screen for fast replace shaker screen . There can be different size or sets of shale shaker to make different size of mud system for different drilling including oil and gas drilling , horizontal directional drilling , coal bed methan drilling , rotary drilling , mining , etc .

The shale shaker can be treating fine solids like sand and silt by installing of desander cyclone and or desilter cyclone . The desander cyclone separate 50 microns and above and desilter cyclone separate 20 microns and above . After desander or desilter separate , the clean mud will be guide into a clean mud tank compartment and solids drop on shaker screen for drying process by 100 mesh to 200 mesh shaker screen . GN Solids can supply a complete solution including shale shaker , mud tanks . Please contact GN Solids for more information .
