Making Greater Efforts for Oil Exploration and Production for the Long Term Boom of Crude Oil in Sichuan Basin Liao Guangzhi,Tang Qingsong,Wang Minglei,Huang Shiwei,Jiang Yuqiang,Wang Zhengmao,Dong Weihong,Hong Haitao,Xu Qinglong,Zhang Xiaofeng,Lin Jianping,Ren Lan,Zhao Yulong,Wang Gaofeng,Zhang Xinyu 2025, 44(3): 1-11.  DOI: 10.3969/j.issn.1002-302X.2025.03.001 Abstract ( )   PDF (2693KB) ( )   Sichuan Basin serves as both a strategic national reserve and a prolific hydrocarbon resource hub. During the Jurassic period, multiple stages of lake basin expansion and vertical stacking developed several sets of high-quality source rocks. The Da’anzhai Member exhibits good favorable source-reservoir configurations with interbedded shales and limestones, and the Lianggaoshan Formation shale had strong hydrocarbon generation capacity and its interbedded shale had good oil storage performance. The Shaximiao Formation, characterized by widely distributed channel sand bodies is further supported by sourceconnected faults and high-quality cap rocks, making it the main battlefield for exploration and development of tight oil. On the basis of reviewing and summarizing the history of Sichuan crude oil exploration and development, including three crude oil battles, one crude oil production enhancement campaigns, and one tackling hard-nut technological problems, it is believed that implementing a new round of crude oil battles is imperative and feasible under the new era and new situation. The new Sichuan crude oil battle targeting unconventional oil is technically feasible with the support of two major technologies including “wideband- azimuth, high-density 3D seismic” and“ horizontal well volume fracturing”. The new battle requires the transformation from limestone to shale sandstone, from fractured to porous reservoirs, from structures to lithology, and the exploration of new exploration models that transition from source to near source. Under the principle of the above “four transformations”, we will carry out a new round of basic research on crude oil exploration and development, from an understanding of the system of crude oil generation, migration and accumulation to making overall arrangements for crude oil work in the Sichuan Basin.“ 3D seismicsystem evaluation-well drilling acceleration-high efficient hydraulic fracturing-long-term development” will be focused to carry out technical research and support, ensuring the achievement of the goal of producing one million tons of crude oil before 2030.

Research on Management Mechanism for Promoting Transfer of Mineral Rights Among Oil and Gas Enterprises Xu Huaming 2025, 44(3): 12-19.  DOI: 10.3969/j.issn.1002-302X.2025.03.002 Abstract ( )   PDF (2644KB) ( )   The mineral rights of the domestic oil and gas enterprises will be reduced by 20 percent between 2025 and 2027. This will affect the resource base for increasing the oil and gas reserves and production. It is necessary to study the management policies of mineral right transfer to improve the capacity of oil and gas enterprises to secure energy supplies. Based on analysis of the cases of mineral right transfer among Sinopec enterprises, this article summarizes the experience and lessons in the transferring process and studies the operational mechanism to accelerate mineral right transfer among the oil and gas enterprises.It also makes a systematic analysis of the related regulations for domestic oil and gas mineral right management and clarifies three ways of sales, joint venture, and cooperation for mineral right transfer among the oil and gas enterprises. Mineral right transfers among the oil and gas enterprises by means of joint venture and cooperation is an effective way to solve the difficulties in oil and gas mineral right management at present. However, some problems exist in the oil and gas mineral right transfers among the enterprises, such as competitive transfers unable to effectively make up for substantial reduction of the area of oil and gas mineral right and a new round of reduction for the high-quality mineral right likely to affect the growth in reserves and production. Consequently, it is proposed that the state should introduce the related preferential policies to accelerate mineral right transfer among the oil and gas enterprises, motivate mineral right holders to participate in the transfer of the low-degree exploration blocks, promote competitive transfer and cooperative transfer of mineral right, increase the total amount of mineral right supplied on the market, and perfect the system of mineral right transfer among the oil and gas enterprises to enhance the market vitality.

Analysis and Implications of Global Patent Portfolios of Foreign Oil Companies Hao Lijuan, Wu Dan, Fan Xianghong 2025, 44(3): 58-65.  DOI: 10.3969/j.issn.1002-302X.2025.03.007 Abstract ( )   PDF (2706KB) ( )   The research on patent applications and patent portfolio strategies of foreign oil companies is of significant reference to China’s oil enterprises in optimizing technological innovation pathways, refining patent strategies, and enhancing patent competitiveness. The patent applications of foreign oil companies have exhibited a “rapid growth-rapid decline-steady development” pattern. The geographical distribution follows a synergistic approach featuring “deepening core markets+penetrating emerging markets+enhancing efficiency through regional cooperation”. The World Intellectual Property Organization (WIPO) and European Patent Office (EPO) have become the main pathways for patent portfolio strategy, and The United States was deliberately chosen as the inaugural country. Additionally, the deployment in emerging markets has taken shape, with Brazil, China and India have become key targets for patent portfolio strategies. Meanwhile, the role of regional patent cooperation organizations has become increasingly prominent, while patent portfolios remain undeveloped in African and other regions. In terms of technology focus, traditional oil and gas technology retains dominance, but the emerging industrial technology is under accelerated development. Carbon capture, utilization, and storage (CCUS) and wind energy technology are worth continual attention. Digitalization and cross-disciplinary integration become the new orientation for patent distribution. It is recommended that China’s oil enterprises should learn from the foreign oil companies, and balance the relations between patent application quantity and quality, particularly controlling quality at the source during patent creation. It is necessary to further enhance patent strategy in the market competition area and emerging industries, focusing on the green and low-carbon technology areas, such as CCUS, wind energy and hydrogen energy. It is also necessary to establish the global synergistic distribution system according to the overseas business demand and continually improve the companies’ global market competitiveness.

Research on Carbon Asset Development and Methodology Formulation Based on Hydrogen Production By Means of Renewable Energy Ma Mingwei,Li Rong,Wang Wei,Liu Xin,Wang Zhiqiang,Xu Liping,Wei Xumeng 2025, 44(3): 96-102.  DOI: 10.3969/j.issn.1002-302X.2025.03.012 Abstract ( )   PDF (2847KB) ( )   Hydrogen energy has become the key force to accelerate low-carbon transition in the areas of industry, building and communications. Green hydrogen produced by renewable energy electrolytic water technology is regarded as the best option for low-carbon transition of energy thanks to its near-zero emission in the production process. Currently, renewable energy hydrogen production has a high cost and a poor economic performance and calls for extra economic results to promote extension of the related technology. This article elaborates the main international voluntary carbon reduction mechanisms and carbon asset development conditions. It points out that the carbon asset development feasibility of the renewable energy hydrogen production projects requires economic performance of carbon reduction and more financial support. The current carbon-reducing methodology of renewable energy hydrogen production faced some challenges in the Chinese practice, such as instability of new energy powered electricity generation and inadequacy of the existing energy storage facilities in particular. To formulate the carbon-reducing methodology of renewable energy hydrogen production suitable for China’s conditions, the article proposes to set a reasonable proportion of renewable energy application, adopt the default value of baseline that is close to and in line with China’s current conditions and simplify operation for identification of the baseline scenarios.
