Example: Nearshore Sands Coastal Plain Nearshore Slope Basin Slide 8 Here is an example where the reflection geometries are fairly diagnostic We have oblique progradation indicated by the seismic reflection geometries This is very similar to the cartoon example covered in lecture 10b We can predict where we would find coastal plain, shoreface and offshore deposits We can then infer that there is a good possibility that we have a sand fairway in the region of nearshore deposits (yellow) Basin Slope Non- Marine Near- shore 10 20 40 50 Coastal Plain 30 Courtesy of ExxonMobil L12 – Data Analysis
