Jay, I will just point out Goodrich Petroleum's explanation. They seem to indicate pressure & porosity are the main factors which seems consistent with your statement.

"John Freeman – Raymond James

I want to get a little bit more detail on exactly the differences you are seeing in Caddo Parish, just what would make for such a difference between the Holland well that you drilled in Caddo Parish on the Bethany Longstreet Field versus the last fields over in Longwood and Caddo Pine, just in terms of any specific differences on what you are seeing on the pressure porosities and things like that.

Gil Goodrich

Yes John, this is Gil, good morning. First of all, as Bethany Longstreet and Shale is located in a little deeper in the section and the Shale is roughly at about 11,700 feet and it has a bottom hole pressure in the neighborhood of about 12,000 pounds. Up at the Longwood area, it is about 10,600 feet in depth and the bottom hole pressure is likely to be around 10,000 or a little less. So we have just by natural gradient, a little bit less pressure up there because of the depth. I would say that probably the bigger driver at least in our mind is that the porosity reading is a digit or two better in the Bethany Longstreet area and by that I mean likely in the 10% to 15% range versus kind of 8% to 13% range up in Longwood. And so, as we look at the development and the porosities we are seeing, we have to believe that that is certainly a factor, I caution again this is one data point so we need to get some multiple wells drilled up there before we really can draw any firm conclusion. But that is our general feeling and belief. This time certainly we think has something to do with the driver mechanism. It does not as I said in my earlier remarks; we think everything to be big as we go in fact the Longwood is actually a little bit thicker than what we see in the Bethany area which is more like 200 feet versus Longwood being 280 feet of thickness."

Jay:

Would you postulate a geologic mechanism for this occurrence, based upon the current knowlege from the logs? Is this too close to home as far as what you are currently working on?
