Search on SONRIS for "permitted wells by parish". you caqn search in a range of dates by parish. This will bring up a list by permit date. You can click on individual wells for their staus and details. The list will indicate the total depth they intend to drill, use this to save time as the you are probally only interested in the deeper wells (CV, HO, HA, etc..)
Also, if you go to the DNR homepage and click on the haynesville graphic it will take you to the HA page. Click on the map and it will take you to the GIS tool. You can overlay the HA wells and many of the approved and pending HA units. This is available in the main SONRIS gis system as well.
