The speed of uploading large seismic datasets on limited bandwidth connections is unreliable. By using Osokey Accelerate you can overcome the bandwidth limitations. This means that seismic data can be delivered in a fraction of the time and larger volume transfer is possible.
Making seismic data easy to view and interact with can help drive new data insights. Osokey Stream is a web-based seismic viewer with intuitive interpretation functionality. This means that anyone can use it and start making new discoveries.
Storing seismic data in cloud object storage is very cost effective. Osokey have developed a Petrel plugin that enables seismic data to be streamed directly from object storage. This means that your geoscientists can easily discover archived seismic data.
Downloading large seismic datasets can be very slow. By using Osokey Accelerate you can speed up seismic download. This means that seismic data can be delivered in a fraction of the time and larger volume transfer is possible.
The compression operates on a trace-by-trace basis. It is able to accommodate sudden changes in amplitude and noise between traces making it suitable for field or processed seismic data. There are no wavelet transforms which means that data with sharp boundaries can also be compressed (e.g. similarity volumes, velocity models with salt bodies).
The The Compression Error Factor (CEF) is defined as the RMS of the sample-by-sample difference as a percentage of the RMS of the original input. Compression Error Factor (CEF) is the only input parameter required. The code internally iterates to calculate the correct parameters to reach the desired CEF. A higher CEF may be acceptable for displaying seismic data, but a lower CEF may be used for data calculations or long-term storage.
Please find below example compression results for different data types. For each data type the same subset of the input data was compressed using different CEFs and the output file size is shown in the chart. A link to the input data is provided and a If you test with your own SEG-Y data you will receive a similar PDF. PDF containing the results can be downloaded.
