Description: S Bottom hole locations for all oil and gas test wells whether directionally drilled or straight (vertical) holes.
D Bottom Hole Location - Bottom hole locations for all oil and gas test wells whether directionally drilled or straight (vertical) holes. For a straight (vertical) hole the bottom hole location will be the same as the surface location. These are extracted from the Michigan DEQ Oil, Gas & Minerals RBDMS database on a nightly basis.

Description: S Directional Line - A line connecting the surface location (wellhead) to the bottom hole location of a directionally drilled oil & gas test well. The actual path from the surface location to the bottom hole location is not displayed.
D Directional Line - A line connecting the surface location (wellhead) to the bottom hole location of a directionally drilled oil & gas test well. A The actual path from the surface location to the bottom hole location is not displayed. A directional line is only created for directionally drilled oil & gas test wells. They are not created for straight wells (vertically) wells since the surface and bottom hole locations are the same for these wells. These are extracted from the Michigan DEQ Oil, Gas & Minerals RBDMS database on a nightly basis.
