An isotropic formation is a rock unit whose physical properties, most importantly permeability, porosity, elastic modulus, and electrical resistivity, are mathematically the same in every spatial direction. In a… Read more →

Isotropic permeability is permeability that is the same in all directions, so the rock conducts fluid equally well regardless of whether flow runs horizontally along bedding, vertically across it, or at any angle… Read more →

Isotropy, in geophysics, rock physics, and reservoir engineering, describes the condition of a medium whose physical properties are identical in all directions, so that measurements of elastic wave velocity,… Read more →

Iterative forward modeling is a geophysical interpretation workflow in which a starting earth model (parameterized by layer velocities, densities, and thicknesses) is used to compute a synthetic seismic response through… Read more →

Iterative methods in petroleum engineering and geoscience are mathematical algorithms that solve equations or optimize parameters by repeatedly applying a computational procedure, updating the solution estimate at each… Read more →
