Interesting what they are hoping to see with four 2D seismic lines spaced at least 3 miles apart. Layout seems to point towards trying to pin down a general trend (e.g. section thickness? pinchout?).

Once this is done, is a second round of seismic in the cards to focus on optimum area?

Is there a lot of deep well control in this area?

"Is there a lot of deep well control in this area?"

I don't know exactly what you mean by that but I do know that in the 70s there were approx 11 deep Smackover wells drilled in this area.

That's what I was asking about. Enough control to allow for good well to seismic correlattions for detailed work on rock properties.

Do you know if there was anything said about source? Shot hole or vibrator? If shot hole, depth and size charges? Any other specs on the seismic acquisition?

Trying to see if they are giving up enough data to point towards a more high resolution / max energy type of seismic.

Thanks for any info that you can share

Sorry. I don't know. I wanted to go to the meeting but I had to work.

What's your overall opinion on this? Is it a last ditch effort to try and find productive areas or is this an indication of something more positive such as trying to find where exactly to place wells?

Without knowing what the exisitng well control is indicating, I am going to guess that whoever is underwriting this seismic shoot is planning to use this data to pin down a pinchout of the porous Smackover facies from south to north. Smackover pinchout play like this are productive along trend - seismic can be used to better ID the pinchout / trap.

So you think the brown dense is over pressured in this area due to the pinch out? What formation do you think are causing the pinch out? Norphlet and upper portions of the smk?

Don't know about the brown dense overpressuring issue, but the upper Smk pinchout option is my first choice for strat concept play.

Norphlet pinchout is a real possibility too. Similar traps in this interval in SE USA.

Pinchouts in any of these horzions created by thinning of the section as one moves north. Wedges out as one moves updip (north)
