COVID-19 Updates for resources sector: fee relief | To report a serious incident to DEM, as required by Section 85(2) of the Petroleum and Geothermal Energy Act 2000, licensees should contact the serious incident reporting hotline on: (08) 8463 6666. For more information please visit the Compliance and Monitoring webpage | DEM-ERD has just released the first “Basin in a Box” data-package covering the Simpson and Pedirka Basins. The dataset is available via the “Data and Publications” page. Each package is a consolidated set of seismic and well data to facilitate new ventures and exploration assessments of frontier basins in South Australia. Data releases for other frontier basins will follow. | Changes to data submission requirements during COVID-19 restrictions. For further information see here.

Seismic data transitioning to the cloud

70 terabytes of petroleum seismic data transcribed from obsolete tapes.

Phase 1 of an ambitious multiphase project to copy all onshore South Australian petroleum seismic data held by the Department for Energy and Mining into the cloud and provide 24/7 self-service access to the public has been completed. The dataset contains over 90 3D seismic surveys and more than 17,000 2D seismic lines throughout the state (Fig. 1). Its replacement value is estimated at $1.85 billion based on modern seismic acquisition costs.

Phase 1 began in late 2017 (see previous MESA Journal article, Seismic data goes digital, in December 2018). Data from approximately 1,800 tapes (the majority of which were obsolete tape-types) was transcribed onto current industry-standard tapes and also delivered on hard drives. The new tapes and a backup copy of the hard drives are securely archived at the South Australia Drill Core Reference Library.

Having all of South Australia’s seismic data available on hard drive has significantly improved the department’s turnaround time for data requests as tapes no longer need to be sent offsite to be read by a specialist company.

Phases 2 and 3 of the project are currently being scoped and costed. Phase 2 involves storage of the seismic data in the cloud as further offsite backup and as the data source for Phase 3, which will see the entire open-file seismic data catalogue of both field data and processed data available for direct download via SARIG. The aim is to complete phases 2 and 3 by early 2020, subject to funding.
