Challenges in seismic rock physics
WebWe systematically analyze the rock physics properties of three types of reservoir rocks: weak-dissolution (Class I), vuggy-fracture (Class II), and faulting-cavity (Class III). It is found that faulting-cavity reservoir has a much lower P-impedance than the vuggy-fracture and weak-dissolution reservoir rocks. WebRegardless of the approach used for seismic reservoir characterisation, there remain challenges. These include: prediction of fluid saturation, especially distinguishing low-saturation gas from higher gas saturations overlap in elastic properties among reservoir facies and rock types, which limits discrimination and classification
