Sequence Stratigraphy
Sequence Stratigraphy Services using Seismic Data
Seismic sequence and facies analysis offers a systematic method to interpret both 2D and 3D seismic data. Every reflection package provides information on depositional history and the display on your work station becomes much more interesting.
We understand that this process can be time-intensive and often the features we look for can be subtle. We can visit your office and work alongside your geoscientists and go through your seismic cube line by line mapping out depositional sequences, systems tracts, and seismic facies. Your geoscientists can then either continue the work we initiate or use the finished product.
This service will be extremely valuable if you are dealing with the following depositional systems:
- Deepwater channels and lobes
- Carbonate mounds and reefs
- Shelf sand-ridges
- Deltas
- Incised Valleys
If on the other hand you are dealing with fluvial to shallow marine reservoirs (those beyond the limit of separability on conventional seismic lines), we urge you to contact a company that can create horizon or stratal (isoproportional) slices for you and then contact us.
Sequence Stratigraphy Services using Well Log Data
Benefits of chronocorrelation vs lithocorrelation were first presented by Exxon geoscientists over 30 years ago and are now widely accepted. Recently the benefits of correlating use sequence stratigraphic principles have been highlighted in both siliciclastic and carbonate reservoirs. Despite all these efforts, most companies are still lithocorrelating and creating cross-sections, which are geologically impossible. In our experience, the primary reason for lithocorrelations is a lack of biostratigraphic data, or the inability to use these data to their full potential.
We can correlate wells for you, provided you have
biostratigraphic or core data. We can work with:
- Palynofossils
- Foraminifera (benthic or planktonic)
- Calcareous Nannoplankton
We can also work with raw biostratigraphic data or reports to create field-scale bioevents and ‘finger-print’ reservoir units.
