SW Extension Shaping up to be 2nd Core Area…


The SW extension is producing some impressive wells.  The area includes San Augustine, Shelby, and Nacogdoches counties.  22 Bcf of gas has been produced with numerous wells already eclipsing the 1 Bcf mark.  The best wells are coming from EOG and Southwestern.  The map below details the producing wells.  It is colored by cumulative gas produced and bubbled by maximum monthly gas production.

This area has emerged as a second “core” area.  The shale is deepest in this area, resulting in higher pressures and higher EURs.  Petrohawk has been discussing this area since the middle of last year.  Below is a slide from their Analyst Day Haynesville presentation.  They estimate this area as having 6-7 Bcf potential.  Not as high as the core in NW Louisiana but much better than the more north Texas acreage.

There still is not an abundance of data for this area but based on the early production from Drillinginfo, it definitely appears to be the second best area of the play.  Second month production values are currently higher than 15 MMcf/d.  We at Drillinginfo are keeping up with this area and this blog will continue to update as more data becomes available.
