A ne pas confondre avec le Light Tight Oil, qu'on appelle régulièrement pétrole de schiste, mais qui est de nature différente (c'est justement pas du pétrole lourd, mais du pétrole léger qui se trouve dans des réservoirs étanches).Shale oil is a type of unconventional oil found in sedimentary rock that requires fractional extraction. The heavier, waxy oil is more difficult and costly to recover than traditional crude.

By Tsvetana Paraskova - Aug 25, 2021,
China announced on Wednesday the discovery of a major shale oilfield in the Daqing Oilfield cluster with expected reserves of 1.27 billion tons of oil, Chinese Xinhua news agency reported.
Daqing Oilfield is one of China's major onshore production centers, and the new discovery is expected to help it boost its oil production in the coming years, according to Xinhua.
Daqing Oilfield, which saw the first exploration for shale oil in the 1980s, now has more than 40 wells producing crude.
China National Petroleum Corporation (CNPC) aims to boost shale oil production from shale formations in Daqing to reverse the decline in the production in the area, the state-held oil giant said on Wednesday, as carried by Reuters.
CNPC has increased efforts to research and drill for shale oil in the Songliao basin where Daqing is located. The company has identified shale oil bearing zones in the Gulong formation, CNPC told a media briefing carried by local television.
"The Gulong shale oil campaign helps to cement Daqing's position as China's largest onshore oilfield as it struggles to replace reserves ... it contributes to ensure national oil supply security," said Fang Qing, general manager of Daqing oilfield, as carried by Reuters.
Chinese oil giants are ramping up exploration for shale oil and gas as part of a mandate from authorities to raise domestic production, which could diminish China's costly dependence on crude oil and natural gas imports.
Yet, China has struggled to develop its huge shale gas and oil resources. The challenges arise because some of the most prolific basins are twice as deep underground as the shale gas resources in some of the most extensive U.S. shale gas plays. The challenging geology leads to higher well drilling and completion costs, lower margins for exploration and production companies, and, at times, mixed results in gas flows.

j'ai du mal à le comparer aux réserves connues ailleurs, notamment le bassin permien car les chiffres que je trouve sont très variables (entre 8 et 60 milliards de barils).
Donc difficile d'estimer le caractère significatif ou non de cette découverte.

By Charles Kennedy - Aug 26, 2021
China’s state-owned oil and gas major Sinopec has struck oil and gas at a field in the northwestern province of Xinjiang, Reuters reports, adding that the reserves at the field are estimated at some 100 million tons.
This would be equal to about 733 million barrels based on a 7.33 barrels-to-the-ton conversion ratio.
The state company said on Chinese social media that it had achieved daily output of more than 6,000 barrels of crude and close to 600,000 cubic meters of natural gas.
The newly discovered field is in a legacy-producing region in the Tarim Basin. It is also the location of the Shunbei field, which produced about 1 million tons of crude oil last year, up by 30 percent from the previous year, and 50 million cubic meters of gas, up 32 percent on the year.

04-Nov-2021
The Shengli Oilfield affiliated to Sinopec in Dongying, East China's Shandong Province, reported a discovery of 458 million tonnes of shale oil, and a shale oil reserve of more than 4 billion tonnes after pilot exploration, according to the China Petrochemical Corporation (SINOPEC).
According to Sinopec, aside from China, only the U.S. has the capability to extract shale oil at present. The Shengli Oilfield's newly discovered shale oil reserve is likely to play a significant role in safeguarding the country's energy security.
https://oilprice.com/Latest-Energy-News ... overy.htmlChina Claims First Offshore Shale Oil And Gas Discovery
By Charles Kennedy - Jul 28, 2022
In a first for Chinese offshore shale, state-run oil giant CNOOC has announced what it claims to be a commercial discovery in the Beibu Gulf in the South China Sea with the tapping of oil and gas flows at a wildcat well.
The discovery, at the Weiye 1 wildcat well, the first shale well China has ever drilled offshore, could be a game-changer for the country’s dependence on oil and gas imports, according to Chinese media.
CNOOC estimates that the Beibu gulf holds some 8.76 billion barrels of shale oil in place, and Thursday’s announcement claimed that the wildcat well flowed 20 cubic meters/day of shale oil and 1,589 cubic meters/day of natural gas, which the Chinese oil giant is referring to as a commercial discovery.
Speaking to the Global Times about the discovery, Lin Boqiang, director of the China Center for Energy Economics Research at Xiamen University, questioned the next steps, including what he referred to as the “technical difficulty of shale oil extraction” and the high costs of production.
While China is thought to have more than 30 trillion cubic meters of recoverable shale gas, it has struggled with development–all of which has been onshore to date.
According to Wood Mackenzie, unconventional oil production accounts for less than 1% of China’s total crude oil output due to “high breakevens and non-commercial economics”, but the country’s NOCs are spending top dollar to develop new technologies to ensure feasibility.
That technological development so far is being heralded by CNOOC as the impetus behind the country’s first-ever offshore shale discovery.
In a note originally published by Thepaper.cn and translated by the Global Times, the head of CNOOC’s exploration department said the success of the first offshore shale oil drilling marked the realization of the independent exploration and development of China's offshore shale oil and gas resources with self-developed technology.
Difficile que ça puisse être économiquement exploitable, si c'est du même genre que le LTO et shale gas américain.

By Charles Kennedy - Aug 11, 2022,
China’s state-run China Petrochemical Group, Sinopec, says it has discovered a massive oilfield in the Tarim Basin, containing 1.7 billion tons of oil reserves.
The discovery is the result of exploration in the Shunbei oil and gas field, said to be one of the deepest commercial fields in the world, in the country’s Xinjiang region.
According to the Global Times, Sinopec’s exploration program at Shunbei includes 117 wells, one of which strikes 9,300 meters in depth. Citing the director of China's Center for Energy Economics Research at Xiamen University, the Global Times said the newest discovery could supply the country’s oil demand for two years.
Shunbei is estimated to have the capacity to produce 244 tonnes of crude oil and 970,000 cubic meters of natural gas per day, according to Sinopec.
The Chinese are targeting the Tarim Basin as having the potential overall to meet domestic oil and gas demand for a decade.
Luo Zuoxian, head of intelligence and research at the Sinopec Economics and Development Research Institute, told the China Daily that while the Tarim Basin is “one of the most difficult to explore due to its harsh ground environment and complicated underground conditions” it has “sufficient energy resources that will guarantee a continuous supply for the country’s future development”. said the discovery will substantially help boost domestic oil and gas output in the country.
The discovery announcement comes on the heels of another major exploration victory for China last month, when state-run oil giant CNOOC made the country’s first-ever offshore shale find in the Beibu Gulf in the South China Sea.
The wildcat well, the first drilled offshore China, is said to be a commercial discovery in a gulf that the Chinese believe holds nearly 9 billion barrels of shale oil in place, though the technological complexity of extraction could pose challenges.
