Figure 9. Digitized points can be combined with other data, including measured sections and wells to create three-dimensional surfaces that honor all available data. These surfaces can then be used to build a reservoir model, based on the properties observed between each bounding surface. In this figure, the photorealistic outcrop model can be seen in detail; digitized points are shown as yellow squares, and a channel bottom surface is shown in green. The channel surface curves off to the right in the distance.
