The "green" circles correlate to wells being on "DRL" (drill) status. I'm not sure of the exact criteria the NDIC uses, but I think the process is something like this. If I'm wrong, someone will likely correct me.
1. First, and most importantly, the map and the file reports cannot be updated until NDIC gets the paperwork from the operator. There is always a lag in getting paperwork into an organization, and then scanning it and transcribing it.
2. If the paperwork is delayed, NDIC has "alerts" to let them know when a well should be reporting.
3. Having said that, I think this is how the process works.
4. Once the permit is issued, the well is put on "LOC" status. "LOC" simply means a permit has been issued; no other activity at the well site.
5. Once the well is being drilled, it goes on "DLR" (drill) status. Once it reaches total depth (TD), the map shows the well with a horizontal line (if it's a horizontal well) and the "green circle" becomes a black dot. If you are suggesting that the rigs have already been taken down from the site, and the wells have reached TD, then I would expect these "green circles" to become black dots soon. If they have reached TD and the "green circles" are still there, I assume the paperwork is still being sent in/processed at NDIC. But once the operators reach TD, they should turn to black dots, even if the wells have not been fracked/completed. Even after the rigs are gone, the wells could still be on "DRL" status while work at the surface is being completed to bring the wells into production.
6. Once the wells have reached TD, the operators are expected to complete them in a timely manner. Because of low commodity prices, operators are now allowed to drill the wells to depth, and then shut them in -- for up to two years -- these are known as "drilled but uncompleted wells" (DUCs). They are drilled to total depth but they have not been fracked/completed. The file report shows them as "SI/NC" -- shut in/not complete (not fracked).
7. Bottom line, if one knows for sure that the drilling is complete, that the wells have reached total depth (and based on the length of the horizontals on the map, I'm sure they have reached total depth), I would assume the paperwork is on its way to the NDIC. Once the paperwork is processed, the "green circles" will become black dots, and then within a few months, one will start see production data, UNLESS the wells are not completed/fracked and go to SI/NC status first.
8. "Green circles" mean "DRL" status -- a period during which, even if the rigs are removed, they are still doing work on the wells to bring them into production, with or without being fracked.
