On July 13, the Tarim Oilfield, a subsidiary of China National Petroleum Corporation (CNPC), announced that its cumulative natural gas supply to the West-East Gas Pipeline network has exceeded 400 billion cubic meters, reaching 400.03394 billion cubic meters. As a primary source for the pipeline, this achievement provides a solid guarantee for the production and daily life needs of nearly 500 million people in downstream regions.

Since the first line of the West-East Gas Pipeline commenced operations in 2004, the Tarim Oilfield has maintained an uninterrupted supply without a single day of disruption. Its gas supply accounts for one-third of the total pipeline transmission volume, establishing it as the earliest, most stable, and largest domestic core gas source. The natural gas covers 15 provinces, autonomous regions, and municipalities along the pipeline route, serving over 120 large and medium-sized cities and significantly improving air quality in central and eastern China.

Confronting world-class challenges such as ultra-deep, ultra-high temperature, ultra-high pressure, and high sulfur content, the Tarim Oilfield has overcome key technological hurdles. It has discovered and developed two trillion-cubic-meter gas fields: Kela-Keshen and Bozi-Dabei. The annual natural gas output has remained stable above 31 billion cubic meters for six consecutive years. Notably, the Kela 2 gas field, known as the "First Source of the West-East Gas Pipeline," has formed China's largest cluster of high-yield gas wells with an annual capacity of over 10 billion cubic meters. A single well's average daily output reaches 800,000 cubic meters, sufficient to meet the daily gas demand of a city with a million inhabitants. Concurrently, through three rounds of expansion, the annual supply capacity of the "First Station of the West-East Gas Pipeline" has been increased to 40 billion cubic meters.

The continuously growing supply data reflects significant ecological benefits. It is estimated that 400 billion cubic meters of natural gas is equivalent to replacing approximately 510 million tons of standard coal, reducing carbon dioxide emissions by about 520 million tons. This carbon sequestration effect is comparable to that of 75 million hectares of forest annually, an ecological benefit akin to "planting" a continuous forest area twice the size of the Yangtze River Delta region. Currently, the oilfield supplies over 2 million cubic meters of natural gas per hour to the Yangtze River Delta and other areas.
