Marc, the best map made public to date which includes fault lines, IMO, is the Petrohawk "NW Louisiana Haynesville: The Core Defined By EUR". Use the link below and save a pdf copy as it is easier to zoom in on the areas you wish to examine in detail. The faults are depicted as thick silver lines tapered at both ends. There are a number shown across the entirety of the Play. If you would like to start with one in particular to get the hang of it, I would suggest the fault that runs NE to SW beginning in sections 29, 32 of 15N - 13W and ending in sections 3, 9 of 13N - 15W.

Sorry I can not get a direct link to work but you will find the link to the map in the original discussion.

Hi Skip

Thanks for the Sec. Township and range information. It gets me oriented in the right direction. You and Les give good answers that are easy to understand. I appreciate that. I hope others have said that.

You are welcome, Marc. You know Keith has me and Les B. on long term contracts? Right? LOL!

Maybe you guys should ask for a raise on your contract? LOL! How do faults help in production or hurt production?

Marc, attached is a collection of maps including Petrohawk's. Faults are one of the reasons for all the 3-D seismic work over the last two years. If the operator knows where a fault penetrates the Haynesville Shale, they can adjust the well orientation.

Thanks for all the maps. The geology of this is very interesting to me. I know the faults impact hydrocarbons. I would guess you would not want to drill straight into a fault. CCG has covered a lot of ground in North LA. How do faults really impact production? You and Skip give great answers. Thanks for taking the time respond.

Marc, the fault causes the formation to be displaced (downward) so the formation would not be continuous at the same depth. Think of a layer with a stairstep. This would not allow the horizontal well lateral to be drilled thru the fault and stay in the same layer.

I see what you mean know. On one side is one layer and the other side is something else. Thus, it would make well placement all that more important. Now I get it. I have reference to the Elm Grove Fault by Seismic folks and others. Have you any idea of what they are talking about?

Marc, reference the attached EnCana map.

Les, what happens if you have land in a section where the fault goes through it as we do. An east west lateral (not a great well) was drilled in this area a yr. ago to miss the fault. Will they be able to go through the fault in future to do a north south well?

KCM, I would think all wells would need be oriented in a way not to drill thru the Elm Grove Fault. Of course that would depend on the throw (displacement) of the fault at the Haynesville Shale depth in your section.
