The utilization of enhanced completion techniques of Reduced Cluster Spacing (RCS) and Short Stage Lengths (SSL) resulted in initial 24-hour production rates as high as 18.4 MMcf/d.
Four of these wells averaged over 10 MMcf/d for 30 days. Wells completed in this manner have shown initial production rates improving by as much as 40%, which the company believes could translate into potential increases to well EURs of 15%-20%. The company's current Proved Undeveloped bookings do not reflect this potential incremental uplift to EURs and the pre-tax discounted (10%) present value of the…
