Core Viewpoint - The article reflects on the journey of scientific exploration in seismology, emphasizing the importance of curiosity, perseverance, and collaboration in overcoming challenges and achieving breakthroughs in understanding earthquakes and underground structures [1][2][3][4][5][6][7]. Group 1: Seismology and Earthquake Research - The initial experiences in earthquake research were shaped by the devastating 1966 Xingtai earthquake, which resulted in over 8,000 deaths and nearly 40,000 injuries, leading to a lifelong commitment to seismology [1]. - The limitations of natural earthquakes for research became apparent in the 1990s, prompting the exploration of artificial seismic sources, including explosives and electric sparks, which faced various challenges [2]. - The introduction of marine air guns for land use in 2006 marked a significant advancement, demonstrating that the generated seismic waves were environmentally friendly and effective for underground exploration [2][3]. Group 2: Technological Innovations - The development of "water bubble sources" and "methane detonation" technologies has emerged as a safe and efficient means for high-precision underground exploration, applicable in urban development and resource assessment [3]. - The research into rock mechanics revealed that rock failure is influenced by "differential stress," challenging traditional views and opening new pathways for earthquake studies [4]. Group 3: Environmental and Safety Considerations - The relationship between shale gas extraction and seismic activity was investigated, leading to the proposal of a "red-green light" warning system to balance energy needs with safety concerns [4]. - Recommendations for enhancing tunnel construction in disaster-prone areas were made, drawing from international experiences to improve resilience against natural disasters [4]. Group 4: Collaborative Efforts and Knowledge Sharing - The importance of interdisciplinary collaboration was highlighted, with partnerships across various scientific fields leading to significant advancements in artificial seismic source research [5]. - The author emphasizes the value of maintaining a "beginner's mindset" and the continuous pursuit of knowledge, encouraging young researchers to remain curious and open to new ideas [6][7].

Core Viewpoint - The article discusses the impact of technological advancements in the oil and gas industry, particularly focusing on the shale gas revolution in the United States and its implications for Chinese companies in the sector [3]. Group 1: Industry Overview - The oil and petrochemical industry has traditionally been seen as reliant on natural resource endowments, particularly oil fields [3]. - The 21st century has witnessed significant technological progress, notably in horizontal drilling and hydraulic fracturing, which have enabled the extraction of previously inaccessible shale gas and oil [3]. - Since 2011, the U.S. has seen a dramatic increase in crude oil and natural gas production, achieving the status of the world's leading producer and gaining energy independence [3]. Group 2: Opportunities for Chinese Companies - The article raises the question of whether Chinese companies have benefited from the U.S. shale gas revolution, indicating that there are indeed opportunities for them to share in the gains [3].
