Thickness Maps

With our geologic framework, we have mapped the significant horizons and faults, with special interest paid to depositional sequences (between sequence boundaries) that are potential reservoirs, sources, or seals. We want to know how thick depositional sequences are, the environments that they were deposted in (EODs), and the types of litholigies that they contain. Thickness maps provide information about the thickness (of course!), but can help us determine how EODs and lithologies vary across the area of interest.

Divide the class time into three (3) segments: the review of the previous exercise, the lecture material presented here, and introduce the exercise. The review of the exercise on Seismic Sequences has eleven (11) slides and takes ~25 minutes to explain. The lecture material contains sixteen (16) slides, and takes ~25 minutes to explain. The introduction to the exercise has six (6) slides, and takes ~10 minutes to explain.

Objectives:

At the end of this lesson, students should be able to:

  • Answer the question as to why thickness maps are important and useful
  • Explain the types of thickness maps
  • Generate time-thickness maps
