Imaging improvement for towed-streamer data using OBN data based on deep learning

Hexiang Zhang, Zhina Li, Peng Wang, Zilin He et autres

Traditional towed-streamer seismic data often face challenges in providing detailed imaging of deep-layer and complex subsurface structures. A promising solution is to supplement towed-streamer data with Ocean Bottom Node (OBN) data. However, conventional methods, which primarily rely on linear weighted combinations, have …

3D Pore-Scale Study of Dynamic Interfacial Interactions Effects in Natural Porous Rocks with Various Pore Structures

Haoyun Li, Yongfei Yang, Q. Zhang, Zhenxiao Shang et autres

Summary Dynamic fluid-fluid and fluid-rock interactions commonly take place during subsurface reservoir exploitation, such as low-salinity waterflooding (LSWF) and carbon dioxide (CO2) enhanced oil recovery (EOR). A fundamental understanding of the two-phase flow behavior under conditions of dynamic interfacial interactions is essential …
