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瓦迪拉班地区的晚侏罗世（启莫里阶晚期）朱拜勒组（Jubaila Fm）露头采集了两条二维地震测线数据。本数据集的核心目标是为朱拜勒组微孔碳酸盐岩的多尺度地球物理表征类比研究提供米级尺度的地球物理图像，以补充近地表测井资料。每条测线长度为600米，本次勘探共布设120个炮点，炮间距约5米。检波器为120台垂直分量纵波（P波）检波器，检波间距约5米，通过手持钻机直接固定于坚硬灰岩露头之上。地震震源为安装于6×6全地形车上的750千克加速落锤震源。所有测线的记录时长为600毫秒，采样间隔为0.5毫秒。数据以SEGY格式按炮集进行排序，炮点与检波器坐标以Excel电子表格形式提供。此外还附带一份PDF文档，汇总了数据处理流程，并提供了一条经处理的SEGY格式测线作为示例。
