I took a few excerpts from earning call Q & A's and an article written recently.  The goodrich question and answer is from memory as I couldn't verify with the transcript yet.

There's been talk the past, I don't know, two or three months, but especially over the course of the last two weeks, about potential lower Smackover [Smackover Formation] over portions of North Louisiana and East Texas. Any commentary on that, in terms of -- given y'alls acreages is further south, whether there's any overlap with either your Louisiana or maybe even more likely some of your stuff in Harrison County that you're not really targeting for the Haynesville at this point?

Miles Allison

Well, we are looking into that. That's an interesting sidebar on the Haynesville play, certainly in Harrison County. We have some data in Northern Louisiana that suggests that it's pretty sparse in that area. But we're gathering data.

Floyd, I know there've been multiple reports of this lower smack [ph] over in Northern Louisiana and given your position there via the Haynesville, is that something that you all have started to take a look at?

Floyd Wilson

We'll certainly look at it, Ron.

Goodrich

And lastly, what about -- there has been a lot of talk about the smack over underneath the Haynesville. Can you all talk about that?

We are aware of that and are looking into that.

Charles R. “Rick” Stone, chairman and chief executive officer of Signa Engineering Corp., also has been working with operators to apply MASTER CLEAR FLUID.

Stone says he has used The Mud Master Group’s fluid system on five wells, all of them Buda horizontals where the water-sensitive Midway, Dexter and Maness shales in the vertical intervals historically dictated using OBM. Next up, he says are horizontals in the Eagle Ford Shale and a deep, high-temperature Smackover exploratory well in Northeast Texas with a planned depth of ±20,000 feet.

“We are conducting hot rolling and high-temperature testing to determine the system’s stability point. The testing will give us an indication of what to expect, and we will push the limits. The temperature at total depth in the exploratory well is expected to be 380 degrees F. I do not think we will be able to go to 380 degrees, but I expect to get somewhere between 315 and 350 degrees F before we have to displace to OBM,” he reveals. “We have a casing seat appropriately located at that temperature/depth range.”
