Austin Chalk - South Texas, Karnes Trough Area


The map below depicts recent Austin Chalk activity in the Karnes Trough area (Karnes, Gonzalez Counties, TX).  The yellow boxes highlight active rig locations while the green provide the details on EOG's Austin Chalk completions.  EOG's Matterhorn well had a "prac IP" of 7088 bopd and 11858 mcfgd equating to 9064 boepd (Source DrillingInfo).  Their nine Austin Chalk completions in Sugarkane Field have prac IP's ranging from 157-9064.  It will be interesting to see if they can repeat these rates in other areas of the play.  Their results to the northeast in Gonzales County have prac IPs ranging from 64-795 boepd. Keep an eye on this one.
