STATE OF THE ART OF WAVELETS: AN APPLICATION OF THE APPROACH OF WAVELETS AS A GEOPHYSICIST IN THE PETROLEUM PROCESSING TOOL ACTIVITY

The investigation of the underground, which has as main objective to identify geological conditions and deposits, needs effective methods so that results obtained are consistent with the reality of the field. In this perspective, using tools that assist in the review process of the studies conducted on site are essential for them to be earned more accurate interpretations. Due to the heterogeneity of multiscale oil reservoirs, to obtain properties equivalent of thinner formations results in a problem because it is variables. In this sense, Wavelets are developed functions through several areas: mathematics, quantum physics, engineering and geology, which allow the processing of data collected in the study area and give a greater brevity content research, since by among them happens multiscale decomposition and, consequently, an adjustment in the processing of rock properties and flow in a reservoir heterogeneities in several scales. This work aims to analyze the use of wavelets in the subsoil investigation process, specifically in hydrocarbon detection. For this, a literature search was made of the issues inherent to the theme and considered relevant for this research. It is found that Wavelets contribute to the effectiveness of geophysical investigations, with great applicability in oil exploration, as it enables the description of geological conditions more safely intervention, and ensuring better results of measurements.
