                                 OVERVIEW

This CD-ROM contains geologic and geochemical data collected as part of the Reservoir Characterization and 3-D Reservoir/Basin Characterization for CD-ROM Projects of the U.S. Geological Survey. Information presented here is intended to address the national plans of Energy Information Transfer and Energy Environmental Investigations and Assessments. This publication contains raw and interpreted data, maps, and other graphic displays for the Upper Cretaceous Sussex Sandstone in the House Creek oil field, Powder River Basin, Wyoming. Location and geologic explanations are included in the Geology of the Sussex Sandstone and other sections.

Data sources include 1) core data from Kerr-McGee, Meridian Oil, and Woods Petroleum Corporations, 2) bore-hole history and lease and field production information from Petroleum Information Corporation, and 3) geologic, geophysical, and geochemical data generated and interpreted by USGS scientists.

This publication is intended to serve a broad audience. An important purpose is to explain geologic and geochemical factors that control petroleum production from the House Creek field. This information may serve as an analog for other marine-ridge sandstone reservoirs. The 3-D slide and movie images are tied to explanations and 2-D geologic and geochemical images to 1) visualize geologic structures in three dimensions, 2) explain the geologic significance of porosity/permeability distribution across the sandstone bodies, and 3) tie this to petroleum-production characteristics in the oil field. Digital publications are an important medium to archive maps, figures, and large volumes of geologic and geochemical data that would otherwise be lost. Movies, text, images including scanning electron photomicrographs (SEM), thin-section photomicrographs, and data files can be copied from the CD-ROM for use in external mapping, statistical, and other applications.

Data has been statistically analyzed and mapped in 2-D and 3-D and included in the "data_set" directory as ASCII-formatted, row- and column-delimited data files. Files located on this CD-ROM can be read on UNIX, Macintosh, and PC/Windows computers. Information on how to access and read the contents is located in the following files: readme1.htm and .txt (readme first), and techinfo.htm (technical information on data sources).
