You are calling this well a vertical Haynesville and you may be right, but it looks like a horizontal Haynesville with a short lateral to me. I've asked my friend, Jay, to clarify the matter . I agree with you, though, the DST looks good at this point.
Gas Flow Rate - 4,790 thousand cubic feet per day (Mcfd)
Water Flow Rate - 100 Bbls per day
Flowing Pressure - 3600 psi
Choke Size - 14/64"
Perforated Interval - 13346' to 13817'
