Description

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.
