URI: https://data.geoscience.earth/ncl/CollarHeadworkType

This scheme specifies concepts used to describe the type of assembly bolted to the production casing to control the well, and to provide access and protection (e.g. from flooding, vandalism). OGC GWML2 refers to Fretwell, et al., 2006 ("Guidance on the design and installation of groundwater quality monitoring points Science Report SC020093") to describe this.
