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.

GN’s products have been applied in more than 70 countries and regions. Next year, GN will definitely improve to provide better products and services to all the clients.
