Map Showing Geology, Oil and Gas Fields, and Geologic Provinces of the Gulf of Mexico Region
Geologic Data Files
The following datasets are available in three formats: ESRI Interchange (.e00), Shapefile (.shp), and Personal Geodatabase (.mdb). Metadata for each layer is encapsulated with each of the files in XML format. The metadata is also available separately as HTML, TEXT, and FAQ format.
Zip files may contain several individual files needed for correct formatting. In order to maintain file integrity, use the "Save Target As" feature in Internet Explorer by right-clicking on the appropriate link.
Gulf of Mexico Geodatabase
1:2,500,000-scale geodatabase feature classes for the Gulf of Mexico.
Saving to a hard drive will result in better performance when using this database.
This personal geodatabase contains all of the geology-related vector files associated with this publication (excluding oil and gas field centerpoints, which are available in raster format only). The geodatabase includes geology, geologic provinces, and annotation layers. ArcGIS software, version 8.3 or later can utilize this dataset.
Datasets are clipped to the map extent and attributes maintained from their respective sources.
Raster layers cannot be stored in this personal geodatabase, therefore the shaded relief image and oil and gas fields need to be downloaded separately (see below).
The purpose of the field centerpoints dataset is to depict the generalized location and production of the oil and gas fields in the Gulf of Mexico. Non-U.S. centerpoints were derived with permission from the Petroconsultants database. U.S. centerpoints are used with permission from the Nehring significant oil and gas fields of the U.S. database. They have been merged and offered in ArcGrid and JPEG raster formats only.
Geologic provinces are used for allocation and prioritization of assessment information. Each province has geologic characteristics that separate them from adjacent provinces, and may be based on dominant lithologies, age of strata, and/or structural type.
The shaded relief image is included to provide general elevation and depth information for aesthetic purposes. No elevation or depth data are provided. The image was derived from GTOPO30 elevation data and GEBCO 1-minute bathymetry grids, which were then exported to a single image. Color gradients were applied in Adobe Photoshop before georeferencing in ESRI ArcMap 8.3.
