Systematic Workflow for Reservoir Characterization in Northwestern Colombia using Multi-attribute Classification
In this study, the SOM results were calibrated to wells that have been drilled to date. Geobodies from these winning neurons, which tied to productive intervals registered in these wells, were then visualized for their thicknesses and areal extents within the reservoir field.

Relating Seismic Interpretation to Reserve / Resource Calculations
In the process of quantifying resources/reserves, geoscientists attempt to employ all the available pertinent information to produce the most accurate results. The presence of direct hydrocarbon indicators (DHI) on seismic data can have a significant impact on the reserve/resource calculations not only for volumes, but also uncertainty levels.
