  • Patent number: 9920435
    Abstract: The present invention refers to a procedure which includes the following objectives: a) To determine the morphology of the micro and nanocavities produced by chemical and/or microbiological corrosion in metallic materials, in the space of three dimensions as well as the effective advance of corrosion, the true length of corrosion cavities and their associated parameters: corrosion vectors, corrosion intensity and determination of the cavities diameter/true length of corrosion ratio, applying scanning electron microscopy (MEB) techniques, and analytic, gravimetric and volumetric formulations; b) To quantitatively determine the rate of chemical and/or microbiological corrosion in metallic materials, through their volumetric and gravimetric properties; and c) To obtain a graphic interface to access the numeric information and the micrographs in a simple and friendly manner.
    Type: Grant

  • Patent number: 9121808
    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.
