To deal with the potential natural gas intrusion, CNX and Repeat Precision decided to alternate between 43 PurpleSeal™ frac plugs and 45 PurpleSeal™ bridge plugs. This design ensured that there would be extra protection, from above and below, throughout the length of the well.
The well was completed without any short trips or motor stalls, and all 88 PurpleSeal™ plugs were drilled out in a single run. Plug debris sizes remained small from the first plug to the last, and drill times averaged less than 13 minutes per plug.
