Comstock Haynesville Operational Update

Comstock Update

Comstock also reported initial results of its Haynesville shale program.  During the first quarter of 2015, Comstock drilled and completed two new Haynesville shale wells.  Both wells were completed using the Company's enhanced completion design.  The Pyle 6-7 #1-Alt H well in DeSoto Parish, Louisiana, was drilled to a total vertical depth of 11,183 feet with a 7,598 foot lateral.  This well has been tested with an initial production rate of 26 million cubic feet ("MMcf") per day.  This well has the highest initial production rate of any well drilled by the Company.  The second well, the Shahan 5-8 1-Alt H, in DeSoto Parish, Louisiana, was drilled to a total vertical depth of 11,233 feet with a 7,421 foot lateral.  This well has been tested with an initial production rate of 22 MMcf per day.

The Company also performed its first re-frac of a Haynesville shale well during the first quarter of 2015.  Following the re-frac program, the Pace 33 #1 well in DeSoto Parish, Louisiana had an initial production rate of 4 MMcf per day, an eight fold increase from the 0.5 MMcf per day before the re-frac.

Isn't 11,000 feet in the bossier zone?

Probably not, od.  The Pyle 6HZ #1, the unit well for HA RA SUH in the Belle Bower Field had a TVD of 11,199'.  The top of the Bossier formation in that area should be close to 10,200'.

Good wells at over 26mmcf so whether they are haynesvilles or bossier doesn't matter.

That's what extended laterals can accomplish.  Improved EUR  and lower cost to produce.  It should be noted however that the lateral lengths are roughly equal to one and three quarter of the linear distance of original well designs that had average EURs of about half the two Comstock HC wells.  Everyone benefits from stimulating the rock that was previously off limits in the north/south unit set back zones.

The results look good on paper but they left out two crucial pieces of information.

1- choke size

2- duration of flow test

It's hard to put a lot of stock into IP rates alone due to the significant variance of these two components across the play.
