ION announces new 3D multi-client reimaging programme offshore Australia

ION Geophysical Corporation has announced a new 3D multi-client broadband reimaging programme offshore Australia. The North Vulcan 3D multi-client reimaging programme covers the northern part of the Vulcan sub-basin offshore northwest Australia in an area known for complex imaging challenges.

The ~17 000 km2 programme seamlessly integrates and reimages data from 15 vintage surveys using modern depth imaging. It builds on knowledge gained from ION’s regional 2D WestraliaSPAN survey and incorporates additional geophysical insight and geological interpretation to create a superior new image and enhanced subsurface understanding.

This proven hydrocarbon province has suffered from a lack of investment, in part due to the poor quality of existing data. Reprocessing has delivered significant imaging uplift in geologies with similar imaging challenges. ION’s state-of-the-art broadband processing and GMO tomography can overcome subsurface imaging challenges stemming from a complicated velocity structure due to both shallow carbonates and salt. This cost-effective reimaging will help de-risk future exploration in this complex area at a fraction of the cost of acquiring new data. There are a number of existing fields and discoveries as well as available acreage in upcoming license rounds within the boundary of the North Vulcan 3D multi-client reimaging programme.

"Based on our recent proof of concept, we expect to reveal new subsurface insights and hope to breathe new life into this relatively underdeveloped area,” said Joe Gagliardi, Senior Vice President of ION’s E&P Business Development group. “The North Vulcan 3D reimaging programme will be available to re-evaluate this complex province and inform investment decisions ahead of upcoming license rounds.”
