EXCO: Decline Curves

EXCO published some interesting information about the decline curves it has encountered so far in its Haynesville Shale wells. The slide below shows the Haynesville horizontal type curve by well over the first 120 days. The angle of the curve isn't much different from the original expectations, but the quantities are definitely stronger.

The company is seeing improved economics in its well development costs. Spud to rig release time has decreased from 70 to 75 days to 45 to 50 days. Costs per frac stage have decreased by approximately 25%, but costs are still approximately $9 million per well. The wells are being completed with 9 to 12 frac stages and the laterals are 3,800 to 4,500 feet.

Should be part of this post

orks out to a 82% decline rate the first year. After high decline for first 30 days looks like 3mmcf2/day for each 120 day period. Taking 1 year production to 4mmcf2/day

Great site. Thanks...
