KOSUN Share: Large-scale oil field discovered in Bohai, China

Large-scale oil field discovered in Bohai, China, CNOOC announced on the 18th that Chinas largest offshore oil field, the Bohai Oilfield, has made great discoveries in oil and gas exploration: Kenli 6-1-3, located in the northern part of Laizhou Bay, Bohai Sea, drilled about 20 meters of oil reservoirs and test single well crude oil production can reach more than 400,000 barrels per year. CNOOC said that the discovery is expected to become the first large oilfield in the Laibei low uplift, which is of great significance for ensuring Chinas energy security, stabilizing the output of eastern oilfields, and promoting the coordinated development of Beijing, Tianjin, and Hebei. The discovery well Kenli 6-1-3 completed a drilling depth of 1596 meters, and the annual output of the tested crude oil

KOSUN share: The “COVID-19” has less impact on Iran’s oil supply

After Japan, South Korea, and Italy successively became the severe disaster areas for overseas epidemics, the epidemic situation in Iran, an important OPEC member, has become extremely serious, and even the Iranian vice president has been diagnosed with the infection. Iran is currently the worlds fourth-largest oil-producing country, and at the same time sits the Hormuz Strait, an oil maritime throat. The spread of the new crown epidemic in the country has caused widespread concern in the international community about the oil market. However, the outbreak may not have a major impact on Iran s own oil supply. First of all, due to multiple factors such as the oil blockade, economic sanctions and the chaotic regional security situation, the Iranian economy is currently in a continuous recessio

Russia and Mongolia have successively discovered large oil fields

Recently, Chinas neighboring country Mongolia has received good news. A large amount of petroleum resources have been explored in the territory, but Mongolias national strength is relatively weak, and it lacks relevant technologies for the exploitation of oil. Although rich oil resources have been found, how to extract these Resources are also a difficult problem for Mongolia. As a neighbor of Mongolia, China also has relatively advanced mining technology and has a wealth of experience in the field of oil extraction. Therefore, Mongolia sent a request to China to invite China to help Mongolia develop oil fields. It is reported that China has opened nearly a thousand oil wells for Mongolia, which also shows that Mongolias oil resources are still quite rich. Prior to this, the Russian side al

KOSUN shares: China Petroleum Pipeline Bureau sets record for Land and Sea Directional Drilling in China

At 5:18 on February 22, the land and sea crossing project of the Zhoushan LNG Receiving Station and Filling Station Project of Zhejiang Province, which was undertaken by the China Petroleum Pipeline Bureau, completed a one-time retraction of directional drilling at Niutoushan, creating the largest pipe diameter in China (1016 mm) , The largest water depth (27 meters) land and sea directional drilling crossing record. Undertaking the two land and sea directional drilling traversing projects of the Niutoushan and Mamu Zhoushan projects are the four companies of the China Petroleum Pipeline Bureau (CPP) known as pipeline special forces. Among them, the Mamu directional drill was successfully towed back in January this year. The Niutoushan pipeline towed back in this construction is 1080 meter

What is the thermal desorption technology in treating the oil based mud drilled cuttings?

Thermal Desorption applies heat to the Oil Based Mud Drilled Cuttings while isolating the flame from the cuttings. The oil vapor is isolated, so it can be recovered, condensed, and recycled, eliminating long-term liability. The cuttings are heated up indirectly in a large diameter, rotating dryer, with the contaminants being vaporized, as the cuttings move forward through the dryer to discharge. A high temperature separator filters vapors, removing dust and leaving recovered oil clean. Vapors are then condensed to a liquid phase and are processed through an oil/water separation system. Recovered water is used to re-hydrate the cleaned cuttings while the recovered oil is used in new mud or fuel in the burners. The system in the market specifically designed for treating oil based cuttings; C

Composition characteristics of solids in drilling fluid and its influence on well drilling

Initially, it is necessary to look into composition characteristics of solids in drilling fluid and its influence on well drilling, so as to remove harmful solids economically and effectively for further recycling. Solids generated in drilling process mainly include mixing clay, weighting substance, cuttings and other solid substance. They are divided into clay, cuttings, weighting substance and solid substance in treating agent according to their sources in drilling fluid. According to the modes of action of them and their ions in water, low density solids further fall into active solids and inert solids. Active solids are easily hydrated and can react with other substances in liquid. This kind of solids has high surface activity and specific surface area with relatively active electroche

Treatment Methods of Harmful Solids in Drilling Fluid

Cuttings are major harmful solids in drilling fluid and affect physical properties of drilling fluid during the whole drilling process, increasing density, viscosity, yield point, water loss, mud cake, abrasiveness, glutinousness and flow resistance of drilling fluid. During drilling process, cuttings may even damage oil and gas reservoirs, reduce ROP, increase rotary table torque and cause blockage during tripping, even resulting in lost circulation, blowout and other complex downhole problems. Besides, cuttings in drilling fluid seriously abrade the circulating system. The key point for achieving drilling fluid recycling is to effectively treat the harmful solids contained within. Solids control system can effectively achieve such a goal. In the system, shale shaker can remove harmful so
