2D near-surface seismic data from the Late Jurassic Upper Jubaila Fm outcrop - Wadi Laban, Central Saudi Arabia

Two lines of 2D seismic data were recorded in January 2018 from the Late Jurassic (Late Kimmeridgian) Jubaila Fm outcrop – Wadi Laban, Central Saudi Arabia. The main objective of this dataset is to complement near-surface well logs with meter-scale geophysical images for multi-scale geophysical characterization analog of microporous carbonate in the Jubaila Fm. The length of each line is 600 m. The survey consists of 120 shots with a ~5 m shot interval. The receivers are 120 vertical P-wave geophones with a ~5 m interval planted directly on hard limestone rock by hand drills. The seismic source is a 750 kg accelerated weight drop mounted on a 6 × 6 All-Terrain Vehicle. The recording length for all lines was 600 ms with a 0.5 ms sampling interval. The data is sorted as shot gather in SEGY format with the receiver and shot coordinates provided as Excel spreadsheets. A pdf file summarizing the processing steps and one example of the processed line in SEGY format is provided as an example.

2018年1月，研究团队于沙特阿拉伯中部拉班谷（Wadi Laban）的晚侏罗世（晚启莫里阶）朱拜勒组（Jubaila Formation）露头区域采集了两线二维地震数据。本数据集的核心目标为通过米级尺度地球物理图像补充近地表测井资料，以支撑朱拜勒组微孔碳酸盐岩的多尺度地球物理表征类比研究。单条测线长度为600米，本次勘探共布设120个炮点，炮间距约5米。接收装置为120台垂直纵波检波器，检波间距约5米，通过手钻直接固定于裸露的硬灰岩表面。地震震源为安装于6×6全地形车（All-Terrain Vehicle）上的750千克加速落锤震源。所有测线的记录时长均为600毫秒，采样间隔为0.5毫秒。数据以SEGY格式存储为炮集数据，炮点与检波器的坐标信息以Excel电子表格形式提供。附带一份PDF文件，汇总了数据处理流程，并提供了一个经处理的SEGY格式测线示例。
