AVOPAK brings powerful visualization and interpretation of pre-stack gather data to the interpretation desktop by generating attributes that can be used to locate hydrocarbon indicators in rock volumes and presenting the gathers in a gallery. Using this gallery, you can dynamically compare gathers to multiple data types such as the stack trace, common offset or angle stack trace, well log curves, synthetics, or extracted seismic sections. This comparison can help reduce risk in prospecting for oil and gas.
Gather data can be analyzed for AVO anomalies in the same project used to interpret traditional stack data. Each gather can be compared to multiple data types such as the stack trace, common offset or angle stack traces, well log curves, synthetics, or extracted seismic sections.
The amplitudes from any horizon interpreted on a gather are automatically graphed by offset, angle, or sin of the angle, and AVO attributes from standard Zoeppritz approximations are automatically calculated. These same attributes can be extracted by horizon or on a regional volume basis and used in standard AVO cross-plotting techniques to isolate the various AVO class sands, stratigraphic trends, and fluid factor. By highlighting various areas in the crossplot, you can isolate these areas and display the results in a vertical seismic section, in the map display and in 3D views. Gathers can also be rapidly visualized for quick quality control, comparison to stack data and attributes, and prospect to analog comparisons.
Using AVOPAK, you can also condition data to help prepare it for AVO analysis. This includes reorganizing the data, improving the signal to noise ratio, and writing the gathers to disk as stacked data, conditioned gathers, generated angle gathers, and AVO attributes.
