Fluid Identification Through Dynamic Modulus Decomposition in Carbonate Reservoirs

摘要

It has been proposed that the appropriate method for interpreting petrophysical properties from acoustic logs is through interpretation in the modulus domain. The frame shear and the frame bulk moduli have been shown to be a function of porosity in quartz reservoirs. We can use the total porosity from logs to estimate the dry frame bulk modulus and, hence, the bulk modulus of the pore fluid, thereby identifying the saturating fluid.
