Last week, GN sent one set 400 BBL capacity mud tank system for an Australia client. GN’s rich experience in manufacturing as per Australia standards, like welding, cable colors and so on, ensures this order. Client also approved and accepted when visited GN on inspection before delivery.

This 400 BBL mud system is for a small rig. Client was worrying about the height of the mud tank will be higher than the drilling mud return pipe of the rig. Actually, GN’s design team has lot of experience in design the mud system, this problem will be considered as one the key factors when make the design. After confirming the height, the proposal provided by GN has a full consideration on let the used drilling mud flow to the tank and ever get into the shale shaker unit easily.

This 400 BBL mud tank system is consisting of 3 parts. Mud recycling tank, mud storage tank and a separate mud mixing unit skid. In consideration of the sufficient tank net volume and height limitation, GN designed the tank with large width which can only be shipped by bulk ship. A separatemixing hopper skid is also for the purpose of making the tank larger net volume capacity.

The equipment configuration of this 400 BBL mud system is simple but effective. 2 unit GNZS703 shale shaker installed on the first tank for coarse solids separation, the shakers occupied almost half area of the tank top, the other half is fixed with one unit mud agitator and also left space for mounting a degasser unit in future in case any request. The second tank is used for active mud storage and mud mixing, four units mud agitators work well to keep the solids in drilling fluids suspending. A separate mixing unit skid is able to be connected with mud tank freely as per site area.

GN solids control has rich experience in designing and manufacturing the mud tank system used in oil gas drilling and other drilling projects. Any request, no hesitate to contact with GN.

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.

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.
