DATA INFORMATION

Data description: 
The data was collected at Curtin NGL training well facility in May-August 2018 using Fotech Helios Theta DAS interrogator. Acquisition parameters were as follows: 18.5 m gauge length, 12.3 m pulse length and 30 kHz pulse repetition frequency. The original data had vertical channel spacing was 0.67 m, however it was later resampled to 5 m/4 ms space/time sampling.

The data is stored in SEG-Y format (phase, 4 byte floating point, IEEE, little endian). One file covers one day of the acquisition. Data stored using 191 traces x 7680 sample frames covering 30.72 s. GPS time stamp for each frame is stored in trace headers (8 byte floating point, IEEE, starting from byte 193)

Description of the data acquisition and initial analysis can be found here:

Data collection time details: 2018/05/16 - 2018/08/09
Number of files & types: 86 files in SEG-Y format. Last six digits before the file extension is the acquisition date in YYMMDD format
Special software required to open files: Data was prepared using RadExPro package (https://radexpro.com/). Most of the conventional seismic software packages should be able to read the data (SeisSpace, Seismic Unix, RadExPro, etc.).
