Range Resources tested reduced cluster spacing on two wells in a producing unit in the Marcellus Shale.
The results are intriguing to say the least. Production came online at roughly double rates of wells that didn’t receive the treatment. The Marcellus has already proven to be resilient to low natural gas prices and an uplift in individual well performance of 100% will only further entrench the Marcellus as a leading shale gas play.
In the first quarter of 2012, Range wells across the board averaged 6.6 mmcf/d and 252 b/d of NGLs and condensate. One well in the liquids-rich portion of the play was completed with the reduced cluster spacing and came online at a peak 24-hr rate of 108 b/d of condensate, 501 b/d of NGLs, and 7.1 mmcfd of ethane rich natural gas. The well had a lateral length of 2,752 ft and was completed with 14 stages.
Improvements like these are exactly what you want to see in a time of low natural gas prices: Good engineering and operational gains make our minerals more valuable.
