Project summary

A collaboration between Oceania Geo, Galilee Energy, STRYDE and Earth Signal Processing to demonstrate the viability of acquiring small footprint 3D seismic surveys using lower cost and lower impact technology for well planning and field optimisation.

Project goals:

  • Provide structural and stratigraphic confidence through 3D imaging.
  • Rapid turnaround to fit within well planning and pad development timeframes.
  • Minimise or remove impact on environment, land holders, and cultural heritage.
  • Low capital outlay to de-risk pad development.
  • Reduce HSE exposure through smaller crews, scale of equipment and time of operation.

"Using high-quality seismic to de-risk production optimisation is a no brainer. It costs~AUD$100k-$250k to acquire seismic to de-risk a 3-5sqkm multi-well pad development where horizontal wells are costing $2m+ per well..."
