Maximum amplitude
I'm a paragraph. Click here to add your own text and edit me. It's easy.


Above figures you can clearly observe different figures illustrating different horizons with different amplitude settings (Maximum and minimum), with figure 1 illustrating the maximum amplitude of the horizons and figure 2 showing the minimum amplitude attribute on the different horizons.
The maximum amplitude is a post-stack attribute that calculates and computes the maximum value of amplitude within a window showing us areas which might have hydrocarbons, thicker prominent boundaries and coarser sands while the minimum amplitude attribute is also a post- stack attribute which is used to compute the minimum value of the absolute value of the amplitude within a window which might indicate finer sand area and thinner boundaries.
In figure 1a, b, c, d we apply the maximum amplitude attribute to the seismic section. In figure 1a it shows that horizon 1 has a mostly average amplitude value with most of it being turquoise and green with some red speckles around the center which might show areas of hydrocarbon, while in figure 1b horizon 2 seems have a mediocre amplitude value with most of the map being turquoise in color, but without any red or higher amplitude speckles or spots anywhere to be found in the map which might indicate the absence hydrocarbons in that horizon. Furthermore, figure 1c shows that horizon 3 has a rather higher amplitude in relation to past two horizons mentioned but also has no areas of high amplitude which might also indicate the absence of hydrocarbon in the section. Lastly, the figure 1d shows that horizon 4 has the highest amplitude of all but as was the case for the past two there are no areas with sudden amplitude spikes which might lead to the notion that this area has no hydrocarbon.
