Rock physics analysis establishes the link between rock properties and reservoir parameters starting from measured well log data, petrophysical evaluations, and laboratory measurements. The properties driven from seismic data may be interface attributes such as Amplitude Versus Offset (AVO) attributes and/or absolute rock properties like acoustic impedance (AI), shear impedance (SI), density (ρ), p-wave velocity (Vp), s-wave velocity (Vs), Vp/Vs ratio, Poisson’s ratio (ν), bulk modulus (K), Young’s modulus (E), or Lamé parameters λ and μ. Often the combination of rock parameters like Vp/Vs ratio, λρ, μρ and Kρ are used for pore fill and lithology identification. Rock properties E and ν are also used for unconventional exploration and development applications.

摘要

Rock physics analysis establishes the link between rock properties and reservoir parameters starting from measured well log data, petrophysical evaluations, and laboratory measurements. The properties driven from seismic data may be interface attributes such as Amplitude Versus Offset (AVO) attributes and/or absolute rock properties like acoustic impedance (AI), shear impedance (SI), density (ρ), p-wave velocity (Vp), s-wave velocity (Vs), Vp/Vs ratio, Poisson’s ratio (ν), bulk modulus (K), Young’s modulus (E), or Lamé parameters λ and μ. Often the combination of rock parameters like Vp/Vs ratio, λρ, μρ and Kρ are used for pore fill and lithology identification. Rock properties E and ν are also used for unconventional exploration and development applications.
