Compression

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.

Our next-generation seismic compression technology offers significant technical and economical advantages to the oil and gas industry.

The technology has achieved an optimal combination of compression quality and performance. Our compression 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. The compression scales across multi-CPUs and GPUs, enabling batch compression and the ability to scale with faster I/O subsystems. On a laptop, it 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.

The compression 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.

Commercial Usage

The compression technology can be licensed for proprietary and commercial software applications, with significant savings in infrastructure costs as well as improved efficiency and user experience. Adding our compression to the Data Layer of the application enables the creation and utilization of the 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, our 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.
