Breathe life into your old (and new) 3D seismic surveys using PaleoScan – the next generation 3D interpretation software application. It is now possible to completely interpret a 3D seismic survey in just a few days.
Fig 1: This is a 3D view of the Maui 3D seismic dataset shown in PaleoScan.
The survey was acquired offshore New Zealand in 1991 - 32 years ago.
Fig 2: This is a horizon slice from the Maui 3D created using PaleoScan. The horizon slice is coloured by an RGB blend of spectral decomposition data, which highlights the depositional system at this level in dramatic style.
Fig 3. This animation shows several sequential horizon slices from the Maui 3D coloured by an RGB blend of spectral decomposition data. This illustrates the depositional system in more detail than the single horizon slice shown above. These horizon slices were created using PaleoScan.
If you currently don't use PaleoScan, or do use it but maybe don't get the full benefit of it as illustrated above, I would like to invite you to send me a SEGY file of one of your 3D surveys and allow me to show you what is possible in a very short time (happy to sign an NDA).
If you are interested, please contact me:
I am confident that I can complement the work done by your own interpreters, by for example:
-
Conducting a fast-track interpretation of a new 3D seismic dataset.
-
Providing a fast second opinion on an important interpretation e.g. a new planned exploration or infill development well location.
-
Interpreting a partner operated 3D seismic survey, which you may not have the time or resources to interpret in house yourselves.
-
Breathing life into an old 3D seismic survey by applying the very latest 3D interpretation functionality available in PaleoScan.
-
Conducting a fast-track 3D seismic interpretation ‘mid-processing’ – one of the best way to provide processing QC.
-
Coaching/mentoring your own staff to do all this themselves with confidence.
PALEOSCAN
Having been a power user of GeoProbe and Petrel over the past many years, I have now adopted PaleoScan as my preferred software application for 3D seismic interpretation.
-
PaleoScan is shockingly powerful ‘next generation’ software, built and supported by a small French company called Eliis based near Montpellier in the South of France.
-
PaleoScan’s powerful functionality allows the very fast interpretation of every mappable horizon in a 3D survey. The resulting horizons can then be coloured by TWT/depth with contours, amplitude (or any attribute) with TWT/depth contours and with RGB blend/spectral decomposition data which can reveal depositional geometries with stunning clarity.
-
The mostly automated interpretation process allows input by the interpreter at key stages in order to create a robust and horizon consistent interpretation. Instead of autotracking horizons one by one - it effectively autotracks all horizons at the same time. The whole interpretation process takes just a few days, the actual time obviously being dependent on data quality and the size of the 3D survey. I continue to be surprised by how well PaleoScan performs in poor quality areas.
-
PaleoScan does not use AI – it uses very clever French algorithms and HI (Human Intelligence).
-
PaleoScan also includes a wealth of other interpretation functionality, for example a very useful data manipulation tool which allows one to change the orientation of a 3D seismic survey in a matter of minutes, for example to be orthogonal to a dominant fault trend. How often have you wanted to do that?
-
PaleoScan has a 3D viewer which is very good for reviewing the final interpretation products, particularly horizons coloured by spectral decomposition RGB data. A complete interpretation from surface to acoustic basement can be reviewed real time by simply rolling the mouse wheel – which I still find breathtaking.
-
The animation above further illustrates the interpretation power of PaleoScan, but one really has to use the software live with two wide screens in order to appreciate its true business value.

The 3D seismic data shown above is from the 3D survey acquired over the Maui gas field in New Zealand in 1991, shown courtesy of the New Zealand Government.
