Take the Eagle Ford as an example. Map the Yield regionally using just the old verticals.
Convert mud weight to pressure. Look at Austin Chalk API gravities of old verticals.
Map the thickness of Lower Eagle Ford, check mud logs and vitrinite reflectance. Map it all up and things fall into place. It doesn't take a rocket scientist just a good data miner and time because once industry gets one the bandwagon, leases go from $200 to $10,000 an acre in a few months

It is part of being a pure exploration geologist not just a "bolt on" geo. How else are new plays found? The interest in the Brown Dense is it's known characteristics as an important source rock. Once it was shown that "it didn't have to look exactly like the Barnett". Unconventional exploration took off.
Usually, only the majors and large independents have the resources to cut teams loose on regional and, for that matter, worldwide projects.

Ken,

I know you were in the business. Do oil and gas companies extensively study old wells before proceding with any exploration?

I was just wondering because SWN has some interesting wells on land they have already leased. Here are a few such as a HA well producing 200bopd with BHP of 4,000+psi, a HA well making 400bopd with BHP of 4,000+psi, a smk A well producing 300bopd with BHP of 6,000+psi. There are many more examples.It almost seems O&G companies should get old wells and look for these high pressure areas and then lease the footprint, test, and then step out if productive.

High formation pressures are indirect evidence of requisite seals as you suggest. It won't be easy finding areally extensive zones that are "economically" thick enough and shallow enough
Comment by North LA on October 18, 2014 at 11:38am

Are you saying they will probably focus on conventional Brown Dense traps? Looks like the LSBD has a lot of variation throughout the extent. Maybe there are layers within the Brown dense which are sealed similar to the CV. I'm no geologist but it appears the seal not only prevents leakage of hydrocarbons but also causes the very high pressures i.e. > than 0.45psi/ft. When I've reveiwed old well data throughout north louisiana it's interesting how at one depth of a formation the flow pressure will be 200psi then at 30 or 40 ft deeper or shallower the flow pressure will be 4,000 psi. I've observed these variances in the Hosston, CV, and Smackover and I've wondered what causes this pressure difference.

Haven't seen any 3-D shoot. I'm retired. Several years ago, a regional look at well logs showed that section between Brown Dense and Upper Smack over was very permeable
and for Brown Dense to work it probably needs top seal. In my opinion, regional 3-D will ferret out a few more "conventional" traps nothing like hot SMKV play of 30-40 years ago.
Comment by North LA on October 17, 2014 at 5:29pm

You have been looking at the recent 3 D shoot Ken? In your opinion the BD won't be productive because of the lack of a seal or sporadically productive where there are seals? Thanks for any input.

Comment by Ken Marx on October 17, 2014 at 2:34pm
Big conventional fields have probably already been found. Brown Dense play looks like Rubble Zone play in Sunniland Trend (S.Fla).
No top seal.
Comment by Ken Marx on October 17, 2014 at 2:30pm
Looks like Southwest has just figured out Brown Dense is not a resource play. Problem..no areal extensive top seal.
Hydrocarbons generated leak to Smack over where it is trapped conventionally.
4-way, 3-way, or strat trap
