... Multimineral analysis that quantifies the volume fractions of minerals and fluids from a set of well logs has been used for reservoir characterization in complex geological settings. However, due to the data errors and the similarity between petrophysical endpoints, the solutions of multimineral...

... that is a regular grid point located in the nearest vicinity of the surface, or that is located in a regular grid square. Next, the DC potential at the endpoint of the extended normal line is computed by bilinear interpolation or by direct assignment, according to whether the endpoint is located in a regular grid...

... in a straightforward way to extrapolate moduli to the critical porosity point using the moduli at zero porosity together with measured moduli at an intermediate porosity. If Hashin-Shtrikman bound equations are required, it is not such a simple problem to extrapolate modulus values at one endpoint from moduli...
