Many exploration geologists who work in data-lean basins or who do not have access to well data turn to published heat flow data as a calibration for basin models. More than one of my clients was surprised when I expressed my reservations. Basin models calculate heat flow so calibrating to published heat flow sounds reasonable. What’s the issue? Heat flow is not a measurement.

Resolving subtle structural and stratigraphic features in land seismic datasets is an arduous task for conventional processing and imaging workflows. In the examples above DUG MP-FWI Imaging has produced a spectacular uplift, with significantly less effort. Even with the additional complexity that comes with onshore data acquisition (such as topography and near-surface effects), DUG MP-FWI Imaging produced far superior results.

DUG MP-FWI Imaging delivers unsurpassed imaging using raw field data as input. It simultaneously solves the challenges of a complex pre-processing and imaging workflow, while removing assumptions. Least-squares imaging of the full wavefield delivers superior focussing, superior illumination, superior vertical and horizontal resolution and true amplitudes. Data courtesy of Shell.

Interview with Tor Åkermoen – CEO Europe Geoex MCGDUG: Tell us a little bit about your seismic data? Tor: Well, Geoex MCG, along with our partners, recently acquired two multi-client 3D surveys in the Norwegian North Sea. The 2020 survey was the world’s first true hybrid 3D acquisition, with OBN (ocean bottom nodes) and high-density streamer data acquired simultaneously.

The traditional seismic processing and imaging workflow has been around for decades. It involves the testing and application of dozens of processing steps such as deghosting, designature, demultiple and regularisation, which are all designed to overcome the restrictions of conventional imaging algorithms. These workflows can be complex, subjective, and very time-consuming due to their serial nature and they often rely on many assumptions and simplifications which require further steps to resolve.

On any 2D dip line, we can see several almost triangular notches, divots or holes in the seabed, some 1.5 km in width and 250 m deep. Upslope, the divot wall is at a lower angle than the downslope face, which is truncated, and erosional. The upslope face is mirrored in the subsurface by a set of reflectors that extend to the same depth. Look for all appearances like prograding units marching back up the slope.

Gondwanan break-up-basins and their multiple source rocksThe advantage of Namibia’s conjugate margin in Uruguay and Southern Brazil is likely to be the sand and clay deposited by the Rio Grande In the face of the embarrassment of riches discovered in the Namibian Orange Basin over just the last two years, one might speculate that had F. Scott Fitzgerald been trained in geology, the Great Gatsby might have opened as follows.

Santos Basin: New seismic data helps de-risk CO₂ contamination for pre-salt explorationCGG’s latest imaging technology delivers unprecedented detail of the deep structure in the pre-salt rift basin to support the identification of mantle CO₂ migration pathways, allowing operators to de-risk pre-salt exploration. The discovery of the giant pre-salt fields in the Santos Basin (See foldout map) positioned Brazil among the world’s ten largest oil-producing countries.

Today’s energy industry faces the unprecedented challenge of balancing energy security, affordability and environmental sustainability. As hydrocarbons are expected to remain major components of global energy demand for the foreseeable future, the upstream sector will play a critical role in meeting this demand, while being challenged to maintain capital discipline and minimize the environmental impact of their operations.
