Marcellus Basin Lateral Well

Repeat Precision completed a 19,585-foot lateral well in Pennsylvania using 88 PurpleSeal™ frac plugs in a single run.

Challenge

CNX Resources took on the challenge of completing a 19,585-ft lateral well in the Marcellus Basin, the longest in Pennsylvania history. Because of its proximity to an active coal mine, limiting natural gas intrusion was critical in case a hydraulic fracture breached the mine.

$A lateral well drilling project performed with 43 PurpleSeal™ frac plugs and 45 PurpleSeal™ bridge plugs near Pittsburgh, PA.$

Solution

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.

‍Number of plugs: 43 PurpleSeal™ frac plugs and 45 PurpleSeal™ bridge plugs
Drill-out time: 13 minute average
Wash time: 27 minute average
Lateral length: 19,586 ft
Casing: 5-1/2-in., 23 lb/ft
Work string: Jointed tubing
Drill bit: Varel SRP4
