2-D Correlation and Stratigraphic Analysis

Abstract

Two-dimensional stratigraphic analysis represents the bridge that joins the more familiar ground of 1-D data with the Star Wars genre 3-D reservoir model construction. Although products are coming onto the market as this book is being written that will allow geoscientists to interpret in 3-D space, the truth is that, for several years to come, the comfortable ruler of interpretation and comparison for most geologists will be a rather traditional combination of 2-D cross sections and maps. It is merely a matter of time before managers are sold well prospects using holograms, and fluvial geomorphologists examine the 3-D architecture of ancient river systems using 3-D images of complete channel belts. However, today it is difficult to shake the experience of decades of making structure and isopach maps when it comes down to bottom-line decision making. Symbolic of this phenomenon is STRATAMODEL™’s STRATAMAP™, a module that turns 3-D grid layers into 2-D maps in order that those accustomed to this format of presentation can relate more quickly. We recognize that currently our 3-D space-filling/model building is driven by a 2-D paradigm, and in this chapter we discuss a set of tools to carry out the interpretive process of framework building in 2D.

The construction of a solid 3-D model starts with the conversion of 1-D data into 2-D panels of interpreted lithologies and petrophysical properties and mapped surfaces. This 2-D interpretation stage is a fundamental conceptual step that forms the skeleton that is subsequently “filled” in 3-D space using a variety
