3D Outcrop-Based Carbonate Seismic Property Model: A Medium to Model the Impact of Meter-Scale Near-Surface Geological Heterogeneity on Seismic Data

The published dataset is a high-resolution 3D seismic property model. The model explicitly captures meter-scale facies heterogeneity representing the typical near-surface geology of desert carbonate strata. The model is provided in 32-bit SEG-Y format, ready for direct use in seismic modeling and simulation software. The model dimensions are ~4 km x 4 km x 155 deep, with a fine grid resolution of 3 m x 3 m x 0.3 m (X,Y,Z).The model includes VP (m/s), VS (m/s), and density (g/cc). The model is constructed based on extensive Late Jurassic outcrop and near-surface core data.

This model accurately replicates complex facies architecture and petrophysical variations observed in the shallow subsurface of the Arabian Desert.
This resource is essential for forward modeling studies and testing advanced acquisition/processing methods designed to mitigate seismic data degradation caused by strong wavefield scattering from shallow geological heterogeneities.

本公开数据集为一套高分辨率三维地震属性模型。该模型精准刻画了代表沙漠碳酸盐岩地层典型近地表地质特征的米级相非均质性。模型以32位SEG-Y格式存储，可直接用于地震建模与模拟软件。模型尺寸约为4 km × 4 km × 155（垂向深度），网格分辨率精细为3 m × 3 m × 0.3 m（X、Y、Z方向）。模型包含纵波速度（VP，单位：m/s）、横波速度（VS，单位：m/s）与密度（单位：g/cc），其构建基于大量晚侏罗世露头及近地表岩心数据。

该模型精准复现了阿拉伯沙漠浅部地下观测到的复杂相结构与岩石物理参数变化特征。

该数据集对于正演模拟研究，以及测试旨在缓解由浅部地质非均质性引发的强波场散射导致的地震数据质量衰减的先进采集与处理方法而言，均至关重要。
