Fracturing and Production

After the NG well has been drilled, what is the "ball park" time frame of fracturing and after frac how long before the well can produce? The reason I ask is that there was a rig set up over the preposed sites for 3 wells that are on my lease in Burleson for almost 2 months. I've noticed that after watching other rigs that this was a long time to be set up. Now, after about 2 1/2 weeks there set up again. The wells are too far from a public place to see what they are doing or have been doing. Just curious. For those of you in Tarrant Co. the wells are behind Southern Oaks Golf Club next to Spinks airport.
