Fractures can increase reservoir permeability, however, they can also increase the probability of accidents such as casing deformation and frac-hit. Therefore, it is of great significance to identify and evaluate the fractures in the shale and tight reservoirs. In this paper, the response characteristics of Stoneley wave and dipole S-wave to fractures intersected with horizontal wells in shale reservoirs have been systematically studied using three-dimensional finite-difference algorithms. The results indicate that both Stoneley wave and dipole S-wave are sensitive to fractures filled with fluid, manifested as energy attenuation. It suggests that both of these two types of mode wave can be used to identify and evaluate fractures near well. Furthermore, Stoneley wave is not sensitive to the fracture filled with calcite, while dipole S-wave is sensitive. Based on the forward simulation laws, two sets of fracture imaging methods have been developed based on Stoneley wave and dipoles S-wave, separately. By comparing the differences between the two images, the fracture filling medium can further be identified. In summary, this paper proposes one detection method of small-scale fractures in unconventional reservoirs based on horizontal well acoustic logging data. It can help to evaluate reservoir permeability in the geological field and predict casing deformation risk in the field of petroleum engineering.Keywords: fracture characterization, shale and tight reservoirs, sonic logging data, horizontal well, Stoneley wavePermalink: https://doi.org/10.1190/image2023-3908956.1FiguresReferencesRelatedDetails Third International Meeting for Applied Geoscience & Energy Expanded Abstracts ISSN (print):1052-3812 ISSN (online):1949-4645 Copyright: 2023 Pages: 1812 publication data© 2023 Published in electronic format with permission by the Society of Exploration Geophysicists and the American Association of Petroleum GeologistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 14 Dec 2023 CITATION INFORMATION Peng Liu, Ning Li, Hongliang Wu, Hao Zhao, Mengsheng Zhang, Huajun Fan, Kai Jiang, Kewen Wang, and Yongjian Zeng, (2023), "Fracture characterization in shale and tight reservoirs using horizontal well sonic logging data," SEG Technical Program Expanded Abstracts : 1760-1764. https://doi.org/10.1190/image2023-3908956.1 Plain-Language Summary Keywordsfracture characterizationshale and tight reservoirssonic logging datahorizontal wellStoneley wavePDF DownloadLoading ...
