When drill some shallow well, such as water well,foundation well, which seems do not need drilling fluid. But in petroleum well drilling, the well depth may reach 7000 meters, this geology is more complex, how to guarantee the property of drilling fluid is the most important work for drilling, And drilling cutting is the main reason to influence fluid.
Therefore, the economic impact of drilling cuttings on drilling a well is very subtle. The increase of drilling cuttings content will not immediately lead to drilling disaster. When the bit stops drilling and the torque increases, the drilling staff immediately know it’s time to pull out; The negative impact of the increase in the amount of rock cuttings will not be shown immediately, so reducing the solid content is similar to buying an insurance policy to prevent accidents. It is difficult to ensure that some accidents (such as sticking) will not happen. No drilling engineering advocates sticking or fishing operations. However, even if special drilling rigs are used in a drilling area, sticking and fishing accidents often occur. The negative effect of rock cuttings is real. Understanding this fact and reasonably treating drilling cuttings on the ground will help to reduce drilling costs and raise the drilling efficiency.
Drilling cutting also destroy the pressure balance between outside and inside of the well, because drilling cutting will influence the fluid density, and reduce the fluidity of fluid. We can know that drilling cutting may destroy. Select the suitable solids control equipment is very important to make sure the drilling success. As usually, shale shaker is the first level separation ,desander is second ,desilter is third level. Sometimes we also will add degasser into the system. and also Decanter centrifuge as the last step. However ,Decanter centrifuge for some project is not necessary.
GN Solids control has been in this industry for more than 15 years, if you have these need, we can provide technical support and equipment for your project.

Drilling cuttings solidification unit is one of the solution of cuttings disposal, it is also called stabilization unit. It is an effective solution for both water based cuttings disposal and oil based/ synthetic based cuttings disposal.
Why should we pay more attention of cuttings disposal？
Obviously, The waste cuttings will damage the environment, lead a heavy pollution and contaminate the under groundwater and influence the Sustainable Development.
There are 4 common ways for the drilling cuttings disposal”
(1) Thermal Desorption Unit, Mechanical separation of drilling cuttings waste treatment with dewatering unit, which is the most popular solution right now
(2) Cuttings re-injection (CRI)
(3) Bio-remediation
(4) Solidification unit/ stabilization unit
GN solids control is specialist for the mechanical separation of drilling cuttings. GNCM-40A & GNCM-40B is our standard drilling waste management system for oil based drilling cuttings, especially for international client, it is design suitable for container shipment. The main difference between them is the installation of the decanter centrifuge, the centrifuge is installed on the telescopic skid in proposal A, the centrifuge is installed on the catch tank on proposal B, they are 2 main methods in the existing projects.
The modular drilling waste management unit including high-G drying shaker unit and decanter centrifuge telescopic skid unit are the main equipments for water based cuttings treatment.
After treated by GN drilling waste management unit, solidification unit will be used for water based mud, and thermal desorption unit will be used for OBM and SOBM. The OOC in the discharged dry cuttings from the vertical cuttings dryer is under 5%, sometimes it reach 3.7%, in some countries, it is acceptable for environmental standard for land filling. In some counties where has more strict environment standard for the cuttings disposal, a further equipments TDU is necessary.

GN Mud Recycling System for ZJ30 Drilling Rig
As a leading manufacturer of drilling mud recycling system and equipment, GN Solids Control could provide the mud system for the drilling rig ranging from 350HP to 2000 HP. This article would give a brief introduction on GN’s drilling mud recycling system for ZJ30 rig.
The drilling rig ZJ30 is defined in China domestic market. This model is also defined as a 750HP rig that is widely known in the market out of China. GN’s ZJ30 drilling rig mud system is designed with the treating capacity of 180 cubic meters per hour and the total mud storage volume is 120 cubic meters.
This mud recycling system includes 3-unit tanks of processing tank, mud mixing tank and storage tank. All 3 tanks are same dimension and the onsite layout is linear type. The processing tank of the mud system includes all the 4 stages of solids control and 5 stages purification process. The first stage solids control is 2 unit shale shakers with 3-panel screens, the capacity of the shaker unit is 120 cubic meters per hour. After the shale shaker, the vacuum degasser is located to remove the gas in the drilling mud thus the working efficiency of the centrifugal pump could be greatly increased, Thus the cyclone would have sufficient pressure when the mud was fed. This ZJ30 rig mud system could be equipped with separate de-sanding and de-silting unit. The de-sanding unit and the de-silting unit is cost less. There is another option of mud cleaner could be installed to replace the de-sanding and de-silting unit. The under shaker of the mud cleaner could be used for further drying the solids particles.
According to the space on the mud tank top, the centrifuge unit is designed located on the second tank. This second tank is divided into 2 or 3 compartments, one of the compartments is used as the centrifuge compartments and the rest compartments are used to store the active drilling mud.
The mud mixing unit is installed on the third tank with 45 kw mixing pump to mix the drilling mud in all the mud storage compartments. Besides the mixing pump, this ZJ30 mud system is also equipped with shearing pump that is used to cut the polymers mud chemicals. This shearing pump would be connected with a chemicals tank which used to mixing the drilling mud chemicals.
GN Economic Mud Recycling Unit
Most of the drilling project will need a drilling mud recycling unit to reduce the drilling cost and promote the drilling process. In normal oil and gas drilling project, always the usage of the drilling fluids is very large that need several mud tanks to store the drilling mud. Different from this type drilling, there are several other drilling projects that no need a large drilling mud volume. The footprint and cost are the key factors the contractor will consider.
As a leading drilling fluids recycling equipment manufacturer and supplier, GN solids control also has a good reputation in the HDD and piling market. This type drilling project need compact structure and cost economic mud recycling unit.
GN has a self-contained drilling mud system designed especially for HDD project. As per the flow capacity, the mud system design is classified into 200GPM, 350GPM, 500GPM, 800GPM, 1000GPM and 1500GPM. Most of the design only has one skid with all primary solids control equipment installed on one tank. According to the mud storage capacity requirement, additional storage tanks may be needed. Some users request decanter centrifuge for fine solids separation. Always this type mud system has all mud recycling equipment, transferring pump and mud mixing equipment. Comparing with oil drilling mud system, the HDD mud system has smaller footprint and the cost is less.
For some drilling project like the piling process or TBM drilling, the separation of drilling mud is not so strict. The contractors only need a de-sanding unit to remove the large size solids in the drilling mud. GN’s this type de-sanding unit includes shaker unit and de-sander cyclone installed on over the shaker. This separation unit can process 2 stages solids control. Under the shaker, a catching tank can used to temporally store the active drilling mud; it also has a transferring pump to pump the mud to drilling rig or to storage tank. The contractor can use other type storage tank to connect with this de-sanding unit and get a skid mounted jet mud mixing unit to compose a drilling mud recycling system that has larger mud storage capacity and mud mixing function.
If you need a drilling mud separation system for small drilling project, please don’t hesitate to contact with GN solids control for a quote and design.
