1. USING POINT BASED TECHNIQUES FOR SEISMIC HORIZONS VISUALIZATION / USO DE TÉCNICAS BASEADAS EM PONTOS PARA VISUALIZAÇÃO DE HORIZONTES SÍSMICOS
Seismic horizon visualization stands as an important knowledge area used to support exploration on the oil industry. Different techniques currently employed to render this kind of surfaces are usually based on polygonal meshes generation, which benefits from graphics boards optimization on drawing triangles. This work is an evaluation of Point Based renderin

2. Caracterização tectono-estratigráfica da sequência transicional na sub-bacia de Sergipe
This thesis deals with the tectonic-stratigraphic evolution of the Transitional Sequence in the Sergipe Sub-basin (the southern segment of the Sergipe-Alagoas Basin, Northeast Brazil), deposited in the time interval of the upper Alagoas/Aptian stage. Sequence boundaries and higher order internal sequences were identified, as well as the structures that affec

3. MAPPING HORIZONS AND SEISMIC FAULTS FROM 3D SEISMIC DATA USING THE GROWING NEURAL GAS ALGORITHM / MAPEAMENTO AUTOMÁTICO DE HORIZONTES E FALHAS EM DADOS SÍSMICOS 3D BASEADO NO ALGORITMO DE GÁS NEURAL EVOLUTIVO
In this work we present a clusterization-based method to map seismic horizons and faults from 3D seismic data. We describe a method used to quantize an initial seismic volume using a trained instance of the Growing Neural Gas (GNG) algorithm. To accomplish this task we create a training set where each sample corresponds to an entry volume voxel, retaining it

4. VISUALIZAÇÃO VOLUMÉTRICA DE HORIZONTES EM DADOS SÍSMICOS 3D / VOLUME VISUALIZATION OF HORIZONS IN 3-D SEISMIC DATA
This work presents aspects of volume visualization of seismic horizons in 3-D seismic data. We consider both the direct and indirect approaches of volume visualization. In the direct approach we investigate the problem of selecting horizons using transfer functions. We present the 2-D opacity technique, which seeks to increase the ability to select horizons
