The two sets of image files included in this section are named:

  1. VERTICAL SLICES OF 3-D PERMEABILITY
  2. PLAN VIEW SLICES OF 3-D PERMEABILITY AND POROSITY

The following two sets of GIF file lists are stored in the 3dvk (3-D vertical slices of permeability) and hporper (horizontal slices of porosity and permeability) directories. GIF files are named and numbered such that external viewers can correctly sequence files in the folders. Images can be displayed as slide shows using an external viewer, such as JPEGView or LView, or can be accessed as movies; links follow the below figures.

Before the movies can be opened, you may need to copy to your hard drive a movie-viewing program; information on how to acquire this freeware and software is listed in the readme for movies file. Due to differences in processing speeds we recommend accessing the stand-alone movie from the movies folder.

3-D permeability images are "smoother" than the 3-D porosity models due to fewer data points; core permeability and porosity data from 10 boreholes are augmented by well-log porosity data from an additional 110 boreholes.

North-South-Oriented Vertical Slices are spaced at 500-m (1,524 ft) intervals and numbered from south to north. Plan-view images are numbered in 1-ft (0.3 m) increments from the basal disconformity datum. Explanation and index map are shown on most images. Each slice has two color bars. They are 1) variation in permeability in millidarcies (mD), and 2) porosity in 1-percent increments. Vertical exaggeration of the 3-D models is listed on images. Yellow dots are sample locations in boreholes.

Most vertical slices show two sand ridges separated by zones of lower porosity and permeability. Horizontal slices illustrate;

1) the highly variable distribution of porosity and permeability in three dimensions,

2) concentration of lowest porosity/permeability zones proximal to the basal disconformity and the western field margins,

3) general upward and seaward increase in porosity and permeability within individual sand ridges, with

4) stacking of greatest porosity/permeability along field axes that resulted from transgressive deposition (westward) of later sand ridges.
