Workshop description

In this workshop the focus will be on the application of reservoir characterization from broadband seismic data:
•    Benefit  of broadband seismic for reservoir characterization
•    Extraction of the seismic wavelet / seismic-to-well matching
•    Using metrics from reservoir characterization to ensure quality in seismic processing

Seismic reservoir characterization relies very much on seismic inversion; two of the main effective parameters of seismic inversion are Low Frequency Model and wavelet which are definitely affected by the type of data that is provided by broadband seismic. In this context, broadband seismic refers to both, broadband acquisition and seismic data acquired using conventional acquisition processed using broadband techniques. 

The workshop will discuss on the one side technical aspects: 
1.    How to incorporate the low frequencies of the broadband data into the seismic wavelet? Should we use longer wavelets and or longer seismic windows during wavelet estimation? 
2.    How to ensure data quality is preserved through the processing sequence? Can metrics from wavelet estimation and inversion, for example, be used to ensure that amplitude, frequency bandwidth and phase are correctly handled.
3.    How the construction of Low Frequency Model is impacted by the increase of low frequency content of the broadband seismic data? 
4.    How the reliable is the low frequency part extracted from the seismic versus the prior information from low frequency model?
5.    How the broadband can impact the downstream workflow of inversion i.e. the transformation of elastic parameters to petrophysical parameters?

The second part of the workshop will concentrate on the experience of the different participants on the impact of broadband data to reservoir characterization through case studies.
