Unconventional oil and gas resources have become the most important and realistic field for increasing China's domestic oil and gas reserves and production. At present, the production scale does not match the massive amount of resources and the rapid growth of proven geological reserves. The challenges of technology, cost, management, and methodology restrict large-scale and economic development. Based on successful practices, a "one engine with six gears" system engineering methodology is put forward, which includes life-cycle management, overall synergy, interdisciplinary cross-service integration, marketoriented operation, socialized support, digitalized management, and low-carbon and green development. The methodology has been proved to be effective in multiple unconventional oil and gas national demonstration areas, including the Jimusar continental shale oil demonstration area. Disruptive views are introduced—
namely, that unconventional oil and gas do not necessarily yield a low return, nor do they necessarily have a low recovery factor. A determination to achieve economic benefit must be a pervasive underlying goal for managers and experts. Return and recovery factors, as primary focuses, must be adhered to during China’s development of unconventional oil and gas. The required methodology transformation
includes a revolution in management systems to significantly decrease cost and increase production, resulting in technological innovation.

Freshwater resources are the material basis for human subsistence and economic and social development. The problem of water resources is very severe in the process of development in the northwestern region of China. This paper further discusses the problem concerning the implementation of the uprinciple of harmonious co-existence of man and nature” during the development of the northwestern region, and suggests that in the process of exploitation and utilization of water resources in the northwestern region it is necessary to consider issues from the fact that the region has only a small total amount of water resource but very large annual evaporation and very small annual precipitation. Efforts should be made to broaden sources of water and economize on water, prevent various kinds of waste of water resources, raise the effectiveness of water use, reduce water pollution, recover water resources and improve the environment. It is advisable to take actively the way of “storing water under the ground”，expanding groundwater and developing groundwater rationally, and meanwhile to adhere to expanding usable freshwater resources continuously.

The commercial exploitation of unconventional petroleum resources (e.g., shale oil/gas and tight oil/gas) has drastically changed the global energy structure within the past two decades. Sweet-spot intervals (areas), the most prolific unconventional hydrocarbon resources, generally consist of extraordinarily high organic matter (EHOM) deposits or closely associated sandstones/carbonate rocks. The formation of sweet-spot intervals (areas) is fundamentally controlled by their depositional and subsequent diagenetic settings, which result from the coupled sedimentation of global or regional geological events, such as tectonic activity, sea level (lake level) fluctuations, climate change, bottom water anoxia, volcanic activity, biotic mass extinction or radiation, and gravity flows during a certain geological period. Black shales with EHOM content and their associated high-quality reservoir rocks deposited by the coupling of major geological events provide not only a prerequisite for massive hydrocarbon generation but also abundant hydrocarbon storage space. The Ordovician–Silurian Wufeng–Longmaxi shale of the Sichuan Basin, Devonian Marcellus shale of the Appalachian Basin, Devonian–Carboniferous Bakken Formation of the Williston Basin, and Triassic Yanchang Formation of the Ordos Basin are four typical unconventional hydrocarbon systems selected as case studies herein. In each case, the formation of sweet-spot intervals for unconventional hydrocarbon resources was controlled by the coupled sedimentation of different global or regional geological events, collectively resulting in a favorable environment for the production, preservation, and accumulation of organic matter, as well as for the generation, migration, accumulation, and exploitation of hydrocarbons. Unconventional petroleum sedimentology, which focuses on coupled sedimentation during dramatic environmental changes driven by major geological events, is key to improve the understanding of the formation and distribution of sweet-spot intervals (areas) in unconventional petroleum systems.

Water resources are basic natural and economic resources of strategic significance and are vital for the high-quality agricultural development and ecological protection of the Yellow River Basin. To implement the national strategy of ecological protection and high-quality development in the Yellow River Basin, it is significant to improve the use efficiency and allocation of water resources in the basin. This study focuses on the high-efficiency utilization and sustainable development of agricultural water resources, adopts the research methods of systematic hydrology, and adheres to an all-encompassing approach to food. Based on the theories and technologies for the optimal allocation of water resources in the process of high-quality agricultural development, it explores the mechanism for the hydrologic process of farmlands and investigates the challenges faced in terms of water use efficiency improvement, optimal allocation of agricultural and ecological water resources, collaborative optimization of water, food, and ecosystem, and construction of farmland information systems. Countermeasures are further proposed. This study reviews the agricultural water-saving and water resource allocation capabilities of the whole Yellow River Basin from a water cycle perspective and is expected to provide basic support for the optimal allocation of land and water resources, high-quality agricultural development, and ecological protection collaboration in the Yellow River Basin.

The Characteristics of water and the issue of water resources in China are mainly discussed in the paper. The viewpoint that the situation of water resources in China cann´t be judged simplily by the amount of average yearly precipitation, and the exploitation and utilization of water resources depend on the humen´s control and management are expounded. In general the water resources in China is enough for using, its unbalnced distribution in space-time is the most problem. Lots of experiences about bringing water under control and using water were accumulated by the Chinese farmers in thousand-years-histroy´s practice. Saving water in agriculture is very important,the key measure is to advocate “decentralized storage and decentralized utilization of water” so that the loss and pollutiion of runoff can be controled. In order to raise the efficiency of water use,a series of research and practical work needs to be carried out.

The efficient exploration and development of unconventional oil and gas are critical for increasing the self-sufficiency of oil and gas supplies in China. However, such operations continue to face serious problems (e.g., borehole collapse, loss, and high friction), and associated formation damage can severely impact well completion rates, increase costs, and reduce efficiencies. Water-based drilling fluids possess certain advantages over oil-based drilling fluids (OBDFs) and may offer lasting solutions to resolve the aforementioned issues. However, a significant breakthrough with this material has not yet been made, and major technical problems continue to hinder the economic and large-scale development of unconventional oil and gas. Here, the international frontier external method, which only improves drilling fluid inhibition and lubricity, is expanded into an internal–external technique that improves the overall wellbore quality during drilling. Bionic technologies are introduced into the chemical material synthesis process to imitate the activity of life. A novel drilling and completion fluid technique was developed to improve wellbore quality during drilling and safeguard formation integrity. Macroscopic and microscopic analyses indicated that in terms of wellbore stability, lubricity, and formation protection, this approach could outperform methods that use typical OBDFs. The proposed method also achieves a classification upgrade from environmentally protective drilling fluid to an ecologically friendly drilling fluid. The developed technology was verified in more than 1000 unconventional oil and gas wells in China, and the results indicate significant alleviation of the formation damage attributed to borehole collapse, loss, and high friction. It has been recognized as an effective core technology for exploiting unconventional oil and gas resources. This study introduces a novel research direction for formation protection technology and demonstrates that observations and learning from the natural world can provide an inexhaustible source of ideas and inspire the creation of original materials, technologies, and theories for petroleum engineering.
