Hue Streams Data Compression Technology
Seismic data is by far the largest consumer of data storage in exploration divisions, accounting for up to 90% of enterprise storage requirements; and the size and complexity is constantly growing and posing several challenges to the industry. With the advent of wide-azimuth seismic and other high-density acquisition technologies, surveys are commonly 40-50 terabytes or more.
Hue Streams is a next-generation seismic compression technology that offers significant technical and economical advantages to the oil and gas industry. Over the past 8 years, Hue has conducted R&D on a data format (VDS) and compression technology for seismic data, and is now making it available to the industry as a stand-alone product called Hue Streams.
Hue’s technology has achieved an optimal combination of compression quality and performance. Hue Streams makes direct access to compressed data faster than direct access to uncompressed data; this turns the whole paradigm upside down. Now, compressed data can finally be a native format and it can be used equally well for seismic acquisition, processing and interpretation. Hue Streams scales across multi-CPUs and GPUs, enabling batch compression and the ability to scale with faster I/O subsystems. On a laptop, Hue Streams compresses SEG-Y at over 300 MB/sec, using only the system CPU. The compression ratio with highly usable data quality is in the 20-30X range.
Hue has recently completed tests with the latest version of one of the most popular industry applications and their most recent compression technology.
Using an industry relevant 24-gigabyte North Sea Quad dataset, here are some of the results:
|Major Commercial Software||Hue Streams||Improvement|
|Resulting file size||2,97 GB||1.69 GB||1.76 X|
|Compression ratio||8.08 X||14.2 X||+1.76 X|
|PSNR||67.8 dB||70.1 dB||+2.3 dB|
|Compression speed||12.89 MB/sec||1000 MB/sec||+77.6 X|
|Completion time from SEG-Y||45 min||1 min 10 sec||-38.6 X|
|Decompression speed||50 MB/sec||10 000 MB/sec||+~200 X|
The compressed file generated by the commercial software has:
- Lower quality, indicated by a lower PSNR (Peak Signal to Noise Ratio)
- Introduces degradation for (important) strong amplitudes more than weaker ones
- Exhibits significant bricking artifacts
- Has a non-homogeneous impact across the spectrum

SUMMARY OF BENEFITS
Hue Streams demonstrates significant technical and economical advantages in several areas:
- Significant reduction of overall storage size required for seismic data.
- Significant time savings across the workflow where seismic data is generated, saved, copied and used.
- Improved people efficiency, number of projects that can be handled by a team, time to discovery, etc.
- Higher interactivity for Interpretation applications. This reduces time wasted and frustration and improves people experience with the application.
Hue Streams can be licensed for proprietary and commercial software applications, with significant savings in infrastructure costs as well as improved efficiency and user experience. Adding Hue Streams to the Data Layer of the application enables the creation and utilization of Hue Streams compressed files directly from the application. Adapters for legacy formats are easy to develop, enabling on the fly import and export to and from legacy, as well as across different formats. In addition, Hue technology can enable on the fly computation from the compressed data using multi CPUs or multi GPUs, in a way that simplifies algorithm development. This will enable significant additional value as a follow up step.
