Sinopec Sets New Vertical Well Depth Record of 5,300 Meters
BEIJING, May 14, 2025 /PRNewswire/ -- China Petroleum & Chemical Corporation (HKG: 0386, 'Sinopec') has announced a major shale gas exploration breakthrough of its Project Deep Earth - Sichuan and Chongqing Natural Gas Base, that its Tiebei 1HF well has been tested at a high daily output of 314,500 cubic meters of industrial gas flow. The vertical depth of the well reaches over 5,300 meters with a 1,312-meter-long horizontal section, setting a new record for vertical depth of shale gas wells in China.
The breakthrough will boost the gas reserves and production efficiency in the Puguang area as well as contribute to the development of ultra-deep shale gas in the Sichuan Basin. The Puguang gas and oil field is the first extra-large deep and high-sulfur gas field in China with large-scale development and has been efficiently developed for 20 years.
To achieve the goal of long-term stable shale gas production, Sinopec is constantly looking for new resources and eyed the Puguang Upper Permian, but most of the resources are distributed in the ultra-deep field with a burial depth of over 4,500 meters, which is regarded as a 'forbidden zone' because of the rapid changes in the velocity of the strata. Sinopec tackled the bottleneck through extensive research and technological innovations to realize a 100 percent drilling encounter rate of high-quality shale in horizontal section with drilling precision comparable to 'threading a needle in the deep underground' to eventually drill the Tiebei 1HF well successfully.
Sinopec's self-developed 175 MPa ultrahigh-pressure (UHP) fracturing equipment dynamically optimizes the parameters on-site with different strategies for each section and opened up a 'man-made gas road' in the high-pressure stratum at the depth of 5,300 meters, bringing back all the resources from the deepest and farthest ends of the gas reservoir to maximize the development.
At present, Sinopec Zhongyuan Oilfield is preparing an overall exploration and development plan for the Upper Permian shale gas in Puguang to promote the efficient transformation of resources.
The exploration and development of shale gas are of strategic importance to China's energy landscape, and Sinopec actively takes the responsibility and discovered the Fuling shale gas field in 2012, which kicked off commercial development of shale gas in China, and Sinopec continues to promote high-quality development of China's shale gas industry.

There Aren't Enough Cables to Meet Growing Electricity Demand
High-voltage electricity cables are in huge demand around the world, so much so that a lack of cabling has become a bottleneck throttling the clean energy transition. So why are cable manufacturers so hesitant to expand? Also, how are these giant cables made? And is China about to eat everyone's lunch? Claes Westerlind, chief executive officer of cable manufacturing company NKT, joins Zero to discuss. This is the third episode in Bottlenecks, a series exploring the lesser known obstacles standing in the way of our electrified future.

China's Cheap Funding Breathes Life Into Leveraged Bond Trades
China's efforts to support the economy by keeping funding costs low are increasing lending among banks, in a sign they may be borrowing cheaply to buy bonds for a profit. The daily volume of overnight repurchase contracts, a popular funding tool for such leveraged bond purchases among financial institutions, rose to the highest since December on Wednesday, according to China Foreign Exchange Trade System data.

How Washington Has Tried to Control China's Tech
For years, officials in Washington have used export controls to slow China's ability to develop cutting-edge technologies, especially ones with military applications like semiconductors and artificial intelligence. Over the past decade, these export controls have driven a wedge between the world's two largest economies. When officials from the United States and China met this week in London to try to work out their differences over trade, export controls were again front and center. 'In eight years of negotiating with the Chinese, I have never had a meeting where they didn't want to talk about export controls,' Jamieson Greer, the United States Trade Representative, said on Tuesday. It is not clear what actions U.S. officials agreed to take in exchange for China easing its exports of rare earth metals — a key sticking point for Washington. But the pillars of U.S. export controls to slow the flow of advanced technology to China appear to remain intact. Want all of The Times? Subscribe.
