WheelerLab: An Interactive Program for Sequence Stratigraphic Analysis of
Seismic
Sections and the Generation of Dynamic Chronostratigraphic Sections
Abstract
WheelerLab is an interactive program that facilitates the interpretation
of
seismic
data
within a sequence stratigraphic framework and the subsequent transformation of the
data
into the chronostratigraphic domain. The transformation enables the identification of significant geological features, particularly erosional and non-depositional features that are not obvious in the original
seismic
domain. Although there are some software products that contain interactive environments for carrying out chronostratigraphic analysis, none of them are open-source codes. In addition to being open source, WheelerLab adds two important functionalities not present in currently available software: 1) WheelerLab generates a dynamic chronostratigraphic section and 2) WheelerLab enables chronostratigraphic analysis of older
seismic
data
sets that exist only as images and not in the standard
seismic
file formats as well as outcrop images and interpreted well sections. The dynamic chronostratigraphic section sequentially depicts the evolution of the chronostratigraphic chronosomes concurrently with the evolution of identified genetic stratal packages. This facilitates a better communication of the sequence-stratigraphic process. WheelerLab is designed to give the user both interactive and interpretational control over the transformation; this is most useful when determining the correct stratigraphic order for laterally separated genetic stratal packages. The program can also be used to generate synthetic sequence stratigraphic sections for chronostratigraphic analysis.
