2D near-surface seismic data from the Late Jurassic Hanifa Fm outcrop - Wadi Birk, Central Saudi Arabia: Shallow marine carbonate platform sediments equivalent to Arabian subsurface reservoirs

Six 2D seismic lines varying in length, geophone interval, and shot spacing were recorded in March 2019 from the Late Jurassic (Oxfordian – Early Kimmeridgian) Hanifa Fm outcrop – Wadi Birk, Central Saudi Arabia. The primary objective of these seismic data is to complement outcrop data with behind-the-outcrop geophysical images for a three-dimensional facies interpretation. The longest profile was a 600 m-long 120 shot-120 receiver line with a 5 m shot and receiver interval, while the shortest line was a 96 m 96 shot-96 receiver profile with a 1.5 m shot and receiver interval. The receivers were 30 Hz vertical P-wave geophones, and the seismic source was a 500 kg accelerated weight drop mounted on a 4x4 extreme utility vehicle. The recording length for all lines was 500 ms with a 0.5 ms sampling interval and a central frequency of ~120 Hz. 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.

于2019年3月，在沙特阿拉伯中部汉尼法层（牛津阶至基默里阶早期）的Wadi Birk露头处，记录了六条长度不一、地震仪间距及炮间距各异的二维地震测线。此地震数据的主要目的是通过露头后方地球物理图像的补充，以实现对三维岩相的深入解析。其中，最长测线为600米长的120炮-120接收器线，炮点和接收器间距均为5米；而最短测线则为96米长的96炮-96接收器剖面，炮点和接收器间距为1.5米。接收器为30赫兹垂直P波地震仪，地震源为安装在4x4极地越野车上的500公斤加速重锤。所有测线的记录长度均为500毫秒，采样间隔为0.5毫秒，中心频率约为120赫兹。数据以SEGY格式排序，接收器和炮点坐标以Excel电子表格形式提供。此外，还附有一份总结处理步骤的PDF文件，以及一条SEGY格式处理示例的剖面。
