Abstract: With the global energy transition and low-carbon development, as well as advancements in offshore oil and gas drilling and production technologies, the energy industry’s perception of deepwater shallow gas has gradually shifted from high-risk “disaster gas” to a commercially viable clean energy resource. However, drilling operations in such gas fields face numerous technical challenges, particularly in ultra-deepwater, extremely weakly cemented formations, including surface well construction, drilling within extremely narrow safety windows, low-temperature cementing, and hydrate prevention. This paper addresses the key technical bottlenecks faced in drilling operations for ultra-deepwater shallow gas fields, proposing innovative technologies such as efficient well construction, precise ECD control, high-performance drilling fluid development, efficient borehole diameter control, and improved cementing quality. These innovations supported the rapid and safe exploration and discovery of the world’s first ultra-deepwater shallow gas field, Lingshui 36-1. Additionally, the paper looks ahead to the new challenges and technologies that may arise in the future development of ultra-deepwater shallow gas fields, proposing important research directions in wellhead stability enhancement, high-build-rate directional drilling tools, new drilling methods, and lifecycle flow assurance, providing valuable technical insights and experiences for the efficient development of ultra-deepwater shallow gas fields.
