GN equipment have mainly three parts equipment, including: Solids control equipment, drilling waste management equipment and replacement shale shaker screens. Most of GN equipment is exporting to overseas market, the scale is about 70% and the rest production equipment is for China local market. As our equipment is comply with international standard, the average price is higher than other China brand. Even though, the overseas client like to buy from GN as better, safer solids control equipment.
1) Drilling waste decanter centrifuge for overseas client
Decanter centrifuge is one important equipment for drilling waste management. With higher bowl speed, the centrifuge can remove much fine solids from the drilling waste, to reduce the waste mud gravity. The centrifuge can also work after flocculent unit, to remove the ultra fine solids after chemical enhancement.
2) Drilling waste vertical cuttings dryer
Vertical dryer is used to treat the drilling cuttings discharged from shale shaker, to recycle the valuable oil based mud and dry the cuttings for easier transportation. After treatment of GN vertical dryer, the OOC can be controlled below 3% to 5%, much convenient for truck transportation and next stage treatment by Thermal desorption unit.
After vertical cuttings dryer, the user can let the recovered OBM going back to shaker tank, or install one decanter centrifuge to treat the OBM, lower down the mud gravity and let it back to centrifuge tank directly.
3) Drilling waste High G dryer
High G dryer is shale shaker with much higher G force. Most client use High G dryer for water based mud cuttings treatment. Actually, this is not convenient because of the shift from vertical dryer to High G dryer when the shift from OBM to WBM happens. And we are developing one Vertical cuttings dryer which can be used for both OBM and WBM, no need change in the whole drilling operation.
