Seismic Inversion and Carbonate Reservoir Characterization
1. Feasible to precisely understand the rock properties – from the spatial variations in impedance contrasts – towards estimating the carbonate reservoir properties (away from production well) – using seismic amplitude data?
2. To what extent, the details on the fracture-size, fracture-shape distributions – could be deduced – using seismic responses (spatial variation of impedance contrasts) – towards identifying optimal drilling locations – in a carbonate reservoir?
3. To what extent, the details on the mineral composition and interaction among minerals – will influence – the fracability of a carbonate reservoir – using the approach of seismic acquisition, processing and pre-stack inversion?
If so, then, how exactly to relate the fracability of a carbonate reservoir to the seismic estimates – on the ratio of differential horizontal stresses; the pressure to initiate fractures; and the closure pressure?
4. Have any major limitations - associated with the ‘isotropic’ seismic inversion algorithm – towards estimating the continuous rock properties – of a carbonate reservoir - at the seismic-scale?
5. How sensitive will be – the coupling between ‘rock-physics modeling’ and ‘pre-stack seismic inversion’ – towards ‘value estimation from grid searching’ – in a carbonate reservoir?
6. Feasible to justify the assumptions of (a) linear approximation for reflectivity; and (b) the natural logarithms of P-impedance, S-impedance & density to have a linear correlation – in a carbonate reservoir – towards simultaneous inversion of pre-stack seismic data?
7. To what extent, the simultaneous investigation of rock properties of a carbonate reservoir – along with the interpretation of seismic attribute variations – would really mitigate the contradictions, if any – arising from – having both explicit and implicit relationships between rock and elastic properties of a carbonate reservoir?
8. To what extent, will we be able to achieve the ‘accuracy’ of ‘seismic inversion’ - in a carbonate reservoir?
What are the consequences of not inverting the elastic properties correctly – in a carbonate reservoir (apart from the difficulty of correlating the carbonate rock properties with the seismic attributes)?
Feasible to perform ‘anisotropic inversion’ – in a carbonate reservoir (in the absence of anisotropic measurements @ both log-scale and laboratory-scale, while the seismic data quality @ far offsets remaining poor)?
9. How easy/difficult will it remain - to capture the impedance contrast - at the fracture-matrix interface - in a carbonate reservoir?
As a practicing geophysical consultant, my approach would be to find an established field with a 3D seismic survey, and see what I can see. This is what I did years ago, perhaps you should try it. The Texas Bureau of Economic Geology has several surveys available - I have no idea of what is available in India, but perhaps since your questions are very general - it doesn't matter.
