4 sets of solid control system desanders for drilling rigs were sold to the Indonesian project

GN Solids Control, a leading provider of solid control equipment in the drilling industry, is proud to announce the successful sale of four sets of drilling rig solid control systems to a major project in Indonesia. These state-of-the-art systems are equipped with cutting-edge technology and are designed to optimize drilling performance and ensure environmental compliance.

Each set of drilling rig solid control equipment comprises two units of the GNZS594J shale shaker, one unit of the GNZS752J-2S desander, one unit of the GNZS752J-12N desilter, one unit of the GNZYQ-1000A mud gas separator, and several agitators. Let’s delve into the functions and benefits of each component.

The GNZS594J shale shaker is a high-performance vibrating screen designed to remove larger particles and solids from the drilling fluid. With its efficient vibration motion, it effectively separates the cuttings from the drilling mud, allowing for better drilling fluid quality and reducing the wear and tear on downstream equipment.

The GNZS752J-2S desander is specifically designed to remove sand and abrasive particles from the drilling fluid. Equipped with multiple hydrocyclones, it efficiently separates the solids from the liquid phase, preventing them from causing damage to the drilling equipment and improving overall drilling efficiency.

The GNZS752J-12N desilter, on the other hand, focuses on removing finer particles and silt from the drilling fluid. By using a combination of hydrocyclones, it ensures that the drilling mud is free from unwanted solids, which in turn enhances the performance of downstream equipment and minimizes the risk of wellbore instability.

The GNZYQ-1000A mud gas separator is a crucial component in maintaining a safe drilling environment. It is designed to separate the gas from the drilling fluid, preventing gas kicks and allowing for the safe venting of hazardous gases. This ensures the safety of personnel and equipment on the drilling site.

To further optimize the drilling fluid properties, the solid control system is equipped with several agitators. These agitators provide continuous mixing of the drilling mud, preventing the settlement of solids and maintaining a homogeneous mixture that enhances drilling efficiency.

With the sale of these four sets of drilling rig solid control systems, GN Solids Control continues to demonstrate its commitment to delivering cutting-edge solutions to the drilling industry. The advanced technology and superior performance of these systems will undoubtedly contribute to the success of the project in Indonesia, ensuring efficient drilling operations and environmental compliance.

GN Solids Control remains dedicated to providing top-quality solid control equipment and outstanding customer service. As the company expands its global presence, it continues to innovate and develop solutions that meet the evolving needs of the drilling industry.

1 unit of GNLW363D decanter centrifuge，the working principal of the decanter centrifuge is as below:


The centrifuge bowl and screw rotates in same direction with a set differential speed, the feeding material is transferred by the centrifuge feeding pump continuously into the screw shaft, then flies to the bowl along with high speed increase. Under the working of centrifugal force, the heavy phase solids deposite on the bowl wall to form sediment layer, the solids is pushed the bowl cone section and discharged from the solids outlet. The light liquid phase forms a liquid ring, which is continuously overflow out of the bowl from the liquid outlets at the big end of the bowl. The straight section of the bowl is the clarification area, and the cone section is extrusion drying area. The decanter centrifuge separation cut point is 2~5 microns, with proper chemicals additives, the separation cut point is up to 2 microns. The centrifuge bowl diameter is 360mm, the bowl length is 1271mm, the max speed is up to 3900rpm, and max G force is 3063G, the designed capacity for water is 200gpm, and typical capacity is 132gpm, the main motor is 50HP, back drive motor power is 15HP.

Solids control equipments shipped to Russia

This week GN solids control shipped one batch of solids control equipments to Russia, the client inspect the equipments in our factory in Beijing before dispatch to Russia. We welcome all the clients to visit our factory before order and after order before delivery.


The solids control equipments they ordered including linear motion shale shaker, mud cleaner, decanter centrifuge, centrifugal degasser, this is their repeat orders since 2017, they keep repeating orders every month during the past years, and make mud tanks system locally. Sometimes they replace the old equipments from their existing rig solids control system.


The shale shaker, mud cleaner, vacuum degasser/ centrifugal degasser, decanter centrifuge are our main products and the most popular products, we have many options for decanter centrifuges with different size from 9 inch to 30inch for different applications, for each bowl size, we have 2 models with different ratio. For 9 inch bowl size centrifuge, we have GNLW224D and GNLW224E-VFD, for 14 inch bowl centrifuge, we have GNLW363C, GNLW363-VFD, GNLW364C-VFD, for 18 inch bowl centrifuge, we have GNLW452, GNLW453C-VFD and GNLW454D-VFD , for 22 inch bowl centrifuge, we have GNLW553C-VFD, GNLW554D-VFD for option, for 30 inch bowl centrifuge, this is the max centrifuge we produced at present, we have GNLW764D-VFD centrifuge, this is mainly for tunneling project which need a huge volume of mud.


The linear motion shale shaker, we have 2 panels, 3 panels, 4 panels and double deck shale shaker for option, all the shaker screens are produced by our own workshop with our brand GN solids control, the composite material shaker screens produced by GN has been approval by many clients in the world for their oil & gas drilling rig.
