Abstract

The present invention is concerned with a procedure to quantitatively determine both, total and effective porosity of carbonated sedimentary rocks, and is based on the elaboration of molds of the rock pores-structure and on the determination of the volumetric and gravimetric properties of the rock and its mold. Determination of the effective porosity is achieved by using an original formula, developed by the authors of the present invention. Additionally, the structure of micro and nanopores in the rock is characterized by scanning electron microscopy (SEM), to identify relevant properties for permeability analyzes such as: dimensions, shapes, type of connections, pore-structure patterns and pore throats. These and other parameters are used as indicators of the reservoir production and storage capacity.
