There are 2 major faults and many minor ones north of Sand Hill Rd. The southernmost one crosses Sand Hill Rd. near my property near where SH RD. ends at parish line. These will impact upon production to some extent. I believe favorably. Depending upon intsity of fracturing in shale I am sure some of oil and gas migrated to sandstone layers. I do not think sufficiently to have dreined shale. It probably continues to this day. The area between faults is of paricular interest to me. I am cautiously optimistic.
