that ok with me if two wells with horizontal at different depth in shale near each other we get good ideal of future EUR in shale in this area of Shelby. I am excite waiting to see what info SB finds out about these wells.

If you look at the plat linked earlier, you can see that there are two seperate laterals for 1-H and 2H. The laterals do converge, with the bottom holes being a bit over 100' apart.

Yep that is what I see I just can not tell what depth each horizontal is and where it is one vertical well bore or two separate

Every E&P con call that has been asked the question has replied that it is not economically feasible to drill multiple horizontal penetrations from one vertical well bore. Forget all the field/permitting regulatory mumbo jumbo. To the best of my knowledge, nobody has drilled, fraced and completed multipile horizontals from the same well bore in onshore NG drilling.

w.r.---so goodrich then is drilling two separate vertical holes very near each other with laterals coming off at different depths in the shale horizontally and perpendicular to each so as to drain a thicker part of the shale? Next question anone know how far out from wellbore the frac goes 360 degrees that will drain the gas from? If formation is 150' thick will a frac from lateral in the middle drain 75' around bore more or less. I am assuming less since they need to drill a SL to produce all? But if that is as far a frac will drain then how does one well drain 40-80 acres? Les B ,SB , D.Gaar. and jfree1 would you add your comment to these questions?

Adubu, operators believe the wellbore will drain ~ 330 ft in each direction from the frac'ed portion of the horizontal lateral. Based on a 4620 ft lateral this equals an 80 acre drainage (660' * 5280' / 43560).

Typical fracture lengths are ~ 200 ft horizontally from the wellbore but less vertically dependent upon the rock quality and shale thickness. Some gas is produced from shale beyond the fractures.

les B --got it---now what is goodrich doing with these 2 wells(SL)--are the laterals at different depths to attempt to drain complete thickness of the shale for 4700' ~75-80acres or what are they doing?

Adubu, I believe one well would be drilled into the Bossier Shale and the other well will be drilled into the Haynesville Shale.

Les and Adubu...........the #1 well has reached TVD in the Haynesville and been logged. It is in the process of drilling the curve to get to the lateral section and could reach TD sometime before the middle of August. At that point the intention apparently is to skid the rig and drill the # 2 to test the Bossier.

Les B-- what you said below is what I was have been saying from the beginning that Goodrich will drill two laterals in the shale --one in upper part to test the Bossier Shale and the 2nd deeper part of the shale in the Haynesville shale. The only question was if they would drill from same vertical wellbore or would they drill 2nd wellbore . From the discussion and review of plats each will have drilled 2nd vertical hole.

SB---Thanks for sharing the info on 1st R Dean Hays well--great information and look forward to results of completion and frac report from you--thanks this well if good will give me hope to the WSW about 2 miles.

Adubu, I will just summarize the items I had said from the start.

- Operators to date had said they plan to drill separate horizontal wells to develop the Bossier Shale & Haynesville Shale.

- The Bossier Shale and Haynesville Shale are separate formations.

- The term "stacked laterals" as used by the TRRC for the Carthage (Haynesville Shale) Field refers to two separate horizontal wells drilled in close proximity.
