FIELDS
From PPDM Wiki
A field is a geographical area defined for administrative and legal purposes. The field name refers to the surface area, although it may refer to both the surface and the subsurface productive zones. In the United States a field is often an area consisting of a single reservoir or multiple reservoirs all grouped on, or related to, the same individual geological structural feature and/or stratigraphic condition. Fields are usually defined at a province/state level but possibly are done at the district level.
The following subsections outline the parent table and associated tables related to this type of production.
