The importance of a good stratigraphic framework
Good quality subsurface evaluations are based on a robust and consistent stratigraphic framework. This framework can be used to guide seismic interpretation and help establish the geological evolution of a basin. At the reservoir scale it aids with determination of reservoir architecture and zonation, and assessment of top seal and intra reservoir seals all of which are key to reservoir modelling and determination of hydrocarbon resource volumes. These workflows are equally applicable to carbon capture and storage projects.
What's involved?
- COLLATE and review legacy & new data to construct consistent stratigraphic framework (age intervals, biozones, lithostratigraphic units)
- RECOGNISE stratigraphic sequences by integration of seismic interpretation, well logs & biostratigraphy. Recognise and map flooding surfaces and unconformities.
- IDENTIFY reservoir pinchouts to aid definition of stratigraphic traps
- IDENTIFY & MAP distributions of reservoir, source rock and seal units
- ASSESS gross rock volume to define hydrocarbon resource volumes or CO2 storage capacity.
