Recently, another good news from KOSUN international market came that KOSUN 1000HP solids control system settled in South Korean market.


Recently, KOSUN delivers a batch of solids control equipment to offshore drilling platform of CNOOC in the Gulf of Mexico. This batch of equipment is specially used for offshore platforms, including 12 KOSUN LS833 Shale Shakers, 12 KOSUN MD210 Cleaners and 12 KOSUN D450 Centrifuges.

Drilling Fluid Shale Shakers Customized by KOSUN for CNOOC
As a solids control equipment supplier for CNOOC, KOSUN specifically designed this batch of solids control equipment used on the offshore drilling platform according to actual service conditions and HSE requirements, integrating such factors as safety, corrosion protection, small footprint, etc., fully satisfying the customer’s requirements with the service tenet of “more than customized”.
As the largest offshore oil & gas producer in China, CNOOC possesses numerous drilling blocks in the Gulf of Mexico. Since 2006, KOSUN has been constantly providing solids control equipment and systems for offshore drilling platforms of CNOOC.


In November 2014, when trucks fully loaded with D355 centrifuges, cuttings dryers and Hi-G dryers were driving out of KOSUN factory, busy frontline production and shipping persons gave gratifying smiles. It took 43 days from placing the order to finally delivering these eight sets of drilling waste management systems. KOSUN Production Center carries out the “Safe and Efficient” production and service concepts once again, saving a lot of time for the customer.


KOSUN has been regarding product quality and services as the basis for corporate survival over the years. In early November, the KOSUN Office in Russia sent a consumer survey feedback form filled with favorable comments.
Being one of the loyal customers of KOSUN in Russia, this famous drilling company has been using KOSUN solids control systems since 2007. Headquartered in Moscow and mainly centralizing drilling blocks in Astrakhan drilling regions subordinate to Lukoil, the company has powerful strength, adopts the most advanced hydraulic drilling rig manufactured by Italy and equips KOSUN mud system for drilling.
After having put into service for a year, KOSUN circulation system works well on customer’s drilling sites without any quality problems. The customer is satisfied with product performance and sends the feedback form for encouragement.
The customer said that, Russia’s climate imposes high requirements on equipment durability and low temperature resistance. No global company can mechanically apply its successful experience gained in other countries when it enters the Russian market. Only Russia on the earth covers 11 time zones. The infrastructures in its drilling blocks have not been fully developed, and the climate in the north is very harsh, so sometimes mechanical equipment needs to be maintained in a low-temperature environment below -40°C. However, KOSUN solids control unit has completely solved the above problems. After long-time use, we deeply trust in and rely on KOSUN equipment, and we will certainly continue to cooperate with KOSUN in the future.

The new KOSUN Headquarters is put into formal use from October 31, 2014, which is located at F11, Lock Building, No.37B Tangyan Road, Hi-tech Development Zone, Xi’an, China.









Near the end of the year, KOSUN Kazakhstan Service Company sends another good news that it has signed a contract concerning ZJ70 circulating system with a local drilling company in Aktobe.





● Equipment Leasing
● Equipment & Spare Parts Sales
● Solids Control Service & Equipment Maintenance
At present, KOSUN has signed a contract concerning providing 20 sets of solids control systems and a large number of accessories as well as mud chemicals, and the contract term is two years. The contract of solids control equipment covers 40 LS583 linear shale shakers, 20 MD106 mud cleaners, 20 VD240 vacuum degassers, 20 DC450S centrifuges, 40 CP56-22 centrifugal pumps, 20 CP56-37S centrifugal pumps, 20 G70-1 screw pumps and 20 JM35 jet mud mixers, which is another bulk order won by KOSUN from a well-known Russian drilling corporation, following its cooperation with many famours companies.


KOSUN Mini LS583 linear shale shaker is compatible with MI-SWACO screens.
This fruitful cooperation is conductive to further increase of KOSUN solids control products in the Russian market share. During the period, the leaders of both parties formally establish the strategic cooperative relationship through repeated close negotiations and in the principle of mutual benefit, win-win and joint development, and plan to set up a warehouse of product accessories in Nefteyugansk by integrating both sides’ advantages, so as to provide a series of localized services of solids control products for numerous Russian drilling companies.
It is well known everywhere that complete solids control equipment is an important demonstration of scientific drilling. The continuous enhancement within almost a decade remarkably brings about better drilling techniques, less maintenance on circulating system, faster drilling velocity and lower costs.
Prior to 1970s, extremely primitive shale shaker took most work in oil drilling industry, but its separation diameter merely reached 400 μm in the best scenario and solid particles went back to circulating system again. Later on, the situation was progressively improved by the invention of ultra-fine mesh shale shaker, desander, desilter, drilling fluids decanter centrifuge, vacuum degasser, mud agitator, concocting devices as well as matching mud tanks, electrical control cabinet and so on, with total weight beyond 5 tons, aggregate power consumption close to 300kW, solid content controlled below 5% and mud’s low density properties available to adjust when needed.

No doubt, these improvements transformed the oil drilling industry, but elevated drilling crew’s workload of in-situ repairing, keep-up, operation as well as energy consumption. Therefore, it has become a common concern for worldwide experts to get simpler equipment, less energy consumption and better reliability when making every attempt to weaken the system performance as little as possible.
Recent developmental demands indicate it has been a trend to get simpler equipment, less energy consumption and better reliability, for which we project to work it out from two aspects: In the long run, we need study the practicality of an one-step method, though with awesome challenges but of adventurous nature. However, things usually develop from junior to senior, from simpler to more complex forms, which is the same with solids control equipment whose better efficiency and lower cost are mainly directed at by solids control scientific research. In the short run, we should develop multi-screen system with larger capacity, more stability and better separation, and work for less desander start-up time or even application, Xi’an KOSUN Machinery Co., Ltd., as the leading pioneer in China’s solids control system, will be devoting to continuous innovations and contribution to the oil drilling industry.
