Significance of the Onondaga Map Layers

Map layers associated with the Marcellus Shale in the interactive mapping system include various Onondaga map layers. This is confusing to many users--i.e., why don't we use maps showing the Marcellus structure? The answer is simple--because we don't yet have those specific map layers for the Marcellus Shale. In order to provide this geological information, we are using map layers created for adjacent stratigraphic units to provide approximately similar information as for the Marcellus.

Structure Map Layers - The Onondaga Limestone and equivalent units underlie the Marcellus Shale. The top of the Onondaga Limestone and equivalents is approximately equal to the base of the Marcellus Shale. So, a map showing the structure on the top of the Onondaga Limestone provides essentially the same information as a structure map on the base of the Marcellus Shale.

Downloads

Download metadata (.htm), spreadsheets (.xlsx), and compressed shapefiles (.zip).

Shapefile Projection: North American Datum 1983, UTM Zone 17 North, Transverse Mercator. A ".prj" file is included in the zip folders.

Data files now include information for bottom holes (Bottom Hole Flag, Bottom Hole Location UTME, Bottom Hole Location UTMN, Bottom Hole Location Longitude, Bottom Hole Location Latitude). In addition, data files for completed wells include 2013 production information (2013 Gas Production Reported, 2013 Oil Production Reported, and 2013 NGL Production Reported).

Marcellus Wells - Completed Episodes Updated 10/2014; data current through 09/2014

 For wells with multiple episodes, each episode is listed and therefore production for the well will be listed under each episode, duplicating reported production on the wells.

The above files contain a list of wells for which WVGES has scanned e-logs and the well penetrated the top of the Onondaga Limestone/equivalent or a deeper formation. The Marcellus may or may not be present/recorded on the log. Note that an unconformity exists between the younger Rhinestreet black shale and the Onondaga Limestone in portions of Cabell, Mason, McDowell, Mingo, and Wayne counties; the Marcellus and other Hamilton Group shales are thought to be missing in these areas (see Schwietering's maps below). The individual scanned TIFF images for these logs are available for free downloading through the interactive map application and at http://downloads.wvgs.wvnet.edu/welllogs/; the associated well data are available on our online "pipeline" data application at http://www.wvgs.wvnet.edu/oginfo/pipeline/pipeline2.asp.
