In the oil and natural gas industry, the reduction of greenhouse gas emissions in the exploration and development (E&P) is an important perspective to achieve both the social demand for carbon neutrality and stable resource supply. Further business development of aquifer CCS and CCUS with enhanced recovery will be inevitable in the next 10 years. In addition, it is also crucial to improve the efficiency of E&P costs through the adoption of digital technology, and to monetize E&P projects at an early stage. Under these circumstances, the construction of a detailed subsurface digital twin that incorporates structure, lithology, physical properties, hydraulics, and mechanical properties is essential for improving the accuracy of understanding the time history and predicting the behavior of subsurface fluid flow, and there is a need to accelerate the development of various technological elements related to the acquisition, processing, and analysis of seismic exploration data. In this paper, we will discuss the current status and future prospects of elemental technology, focusing on the optimization of spatial sampling and the expansion of broadband seismic exploration, mainly for seismic data acquisition, while looking at the complementary development of data acquisition and processing that has resulted from the advancement of innovative technologies such as Full Waveform Inversion (FWI). In addition, we will discuss recent advances in sensing technologies such as fiber optics and IoT technologies that enable automated data acquisition from the perspective of efficient seismic data acquisition and integration, as well as approaches to seismic exploration for reducing environmental impact and promoting environmental protection.
