The total crude oil production of the Bayan Oilfield in Inner Mongolia, China, has surpassed 6 million tons

The cumulative crude oil production of the Bayan Oilfield in Bayan Nur, Inner Mongolia, has exceeded the 6 million ton mark. This comes just seven months after it surpassed 5 million tons in December 2025, marking another million ton milestone.

In the first half of the year, the oilfield produced over 870,000 tons of crude oil, completing 51% of its annual target. Its daily output remained stable at 4,800 tons, up 20% year on year, contributing nearly one third of the daily production of the Huabei Oilfield.

河套盆地成藏条件复杂，主力油藏平均埋藏深度超过5000米，是国内最深的整装陆相碎屑岩油藏。自2018年首口高产商业油井诞生以来，高效开发持续加速：第一个百万吨增量用时49个月，随后四个百万吨分别缩短至13个月、10个月、9个月和8个月，第六个百万吨更是压缩至仅7个月。效率持续攀升，周期不断缩短，整体呈现跨越式增长态势，彰显了勘探开发能力的持续提升。

Currently, the Hetao Basin, where the Bayan Oilfield is located, is still in the early stages of exploration and development. Proven reserves account for only a portion of the estimated resources, leaving considerable room for further reserve growth and production increases. According to the plan of Huabei Oilfield, the Bayan Oilfield will continue to promote integrated exploration and development, accelerate the construction of production capacity in new blocks, and strive to build a million-ton crude oil production base during the 15th Five-Year Plan period (2026–2030). As an important replacement area for Huabei Oilfield’s crude oil production growth, the sustained development of the Bayan Oilfield is of positive significance for ensuring regional energy supply.
