Finite element method-based resistivity simulation and water saturation calculation of irregular laminated shaly sandstone

Abstract: Shaly sandstone reservoir is one of the most significant targets in petroleum and gas exploration. However, the influences of various factors on the resistivity of irregular laminated shaly sandstone are yet to be determined, and it is extremely challenging to accurately calculate the water saturation. By considering shaly sandstone in Zhujiang Formation of Neogene in Pearl River Mouth Basin as an example, this research extracts the shale distribution form and the pore structure by image processing, simulates … Show more

“…As sandstones are one of the most common rock formations (Yin et al, 2021), it is essential to study the changes in resistivity to investigate the geological structure and solve related geological problems. Previous studies have focused on the influence of fractures (Park et al, 2017), pressure (Amalokwu and Falcon-Suarez, 2021;Zheng et al, 2023), temperature (Zhang et al, 2016;Liu et al, 2020;Yuan et al, 2022), and rock type (Wu et al, 2023) on rock resistivity. However, research on the resistivity of sandstone is not extensive enough.…”
