A petroleum field that produces from the New Albany Shale Formation.
Fields producing gas from the New Albany Shale are handled differently than other petroleum fields in several ways:
Only wells completed for production from the New Albany Shale are included in a NAS field. No other wells within the NAS Field Outline are considered part of the NAS field.
NAS fields can overlap the boundaries of non-NAS fields. They may not overlap with another NAS-field; if the outline would cross over the outline of another NAS field, the fields should be consolidated into a single NAS field.
At least for the short term, well counts and Pay Zone Summaries for NAS fields may not be correct because wells in a NAS field that overlaps a non-NAS field may share some of the same wells. This is a design issue that will be corrected when time permits.
The reason NAS fields are handled exceptionally is avoid having many non-NAS oil and gas fields with well-established local names from being cobbled up by consolidation into "mega NAS fields" whose names are not helpful in describing the locations of the smaller oil and gas fields.
