Geophysics has attributions of a security nature, due to its implications in the diagnoses of the configurations of the subsoil in environmental, hydrological and geotechnical matters, since in the latter it plays a fundamental role in the criteria that establish the norms in which the systems of piers and foundations, will possess the characteristics that will provide resistance and stability to the buildings.
On the other hand, the contractual revisions in legal matters in my opinion would require substantial changes, to create responsibilities that can reduce incidents due to issues attributable to the intervention of construction activities that could generate structural changes in the buildings as a result of the symbiosis of efforts caused by factors in which factors of change in the subsoil intervene, in that it would be that a reform to the laws arose from the need to increase safety in Engineering.
The importance of incorporating petrophysical models in the oil industry lies in the adaptation of extraction techniques conducive to the challenges involved not only in the new leads and plays recently announced, but also in seeking to rectify deposits considered depressed, of which adequate petrophysical studies, would help efficiently.
Application of micromechanical methods in a unified petrophysical model
Sandy-Clay Formations
The objective is to analyze the differences between simulated physical properties from a hierarchical petrophysical model, with different simulation techniques and to establish relationships between simulated physical properties.
The petrophysical evaluation in sand-clay reservoirs is an important issue worldwide due to the presence of hydrocarbons in this type of formation. The calculation of physical properties in sand-clay formations depends mainly on the petrophysical model used and must consider the spatial distribution of clay.
In this study, the simulation of physical properties is carried out with a hierarchical unified petrophysical model for sand-clay formations that consists of three levels of homogenization: 1) pores containing fluids and clay 2) sandstone composed of quartz grains, structural clay 3) formation composed of sandstone and layered clay intercalation. Physical properties, such as transit time of P and S waves, electrical resistivity, density, neutron porosity and gamma rays were simulated with two different techniques, the first; from micromechanical methods (Approximation of the effective medium, EMA).
