While the average may be a gauge as to the other may average, you have to consider a few points.
They had a reason to start drilling on the locations. It may have been the percentage of leasehold, or a potential loss of the same. It is possible that they are drilling the ones most likely to produce the best results based on the geological makeup.
Further you never really know if they are testing different bore path techniques or completion techniques either in some of these wells or the future one you have the most interest in.
At best it is still a gamble without more data than we will have access to.
Following a well that is being fracked? Not really. Not unless you have contact with someone that may know what is going. With some subscription databases, we may see “clues” as to what the progress actually is. Like when they report the chemical usage. You may also be able to tell when the rig left the location, but that does not mean a fracturing crew was available and able to start right away. Eyes on the ground is the best way and sometimes there is chatter by what is going on at various coffee shops, restaurants, gas stations, or other locations some of the vendors show up at. Most of the time they don’t even know the well name of the Section Township and Range that they are working on. They might know of only as the “Birt” well pad.
From public access data, the issuing of a Production Unit Number (PUN) has always been my first clue that the well was now in operation. These are usually within ±10 days of the well being completed. After that the completion report.
