Rock physics of the Wolfcamp Formation, Delaware Basin

Abstract: Production from wells in organic-rich shales often shows considerable lateral variation. Reliable predrill methods to characterize the lateral heterogeneity of such reservoirs are required to optimize the trajectory of lateral wells in these low-permeability reservoirs. Petrophysical interpretation of measured well logs provides information on mineral, porosity, and kerogen content. Combining the results of petrophysical analysis with P-wave, S-wave, and density logs allows generation of a probability density … Show more

“…To investigate the impact of anisotropy on geostress, this study also considered the widely adopted and successful porous elastic models. , These models are classified as isotropic and do not account for variations in vertical and horizontal Young’s moduli or Poisson’s ratio. The mathematical representation can be found in eqs and , while eqs and represent the isotropic Young’s modulus and Poisson’s ratio, respectively. σ h = μ iso 1 μ iso false( σ normalv α p normalP false) + E iso 1 μ iso 2 ε h + E iso μ iso 1 μ iso 2 ε H + α p P σ H = μ iso 1 μ iso false( σ normalv α ...…”
