stacked laterals---WHO HAS THE KNOWLEDGE TO ANSWER?
experts--tell us about stacked laterals---I assume they are mutiple lateral legs at slightly different depths in same formation like bossier shale upper vs lower vs haynesville---but are they from same vertical hole or do they require drilling another well vertical bore and then lateral horizontal leg off into same formation one on top of the other. I looking at well that was permitted by GoodRich Petroleum in NNE Shelby county the R Dean Hays (SL) #1H and #2H. The plat look like drilled off same pad site but can not tell if same vertical hole or what---I assume this is good sign they found something good is 1st well that was spud about 5-6 weeks ago and #2H (SL) permitted today--look forward to reading knowledgeable reply to this discussion

Hardage, I am delighted to think that you think the Dean Goodrich at Joaquin is going to be a good shale well. I have heard it is both Bossier and Haynesville. It seems people around there are not talking about it that much. I have been trying to find out; I know many there who use computers, but they are not writing to the website. I have minerals that would be a "neighbor" to it and of course, I am HBP'd; however, rumor had it at one time, that the shale might have to be released. I do not think there will be a lease, but mine has been sold, farmed out over and over; thus, I must check to see who even has my deep zones if they do find the shale. Of course, I suppose at that point, they would come to me. LOL So, is it true that they are drilling two wells. I did heard that it was strong and I wonder if they did the second to calm it down. I think they had to stop as they had equipment lost; therefore, I assumed that they shut down for phishing. PLEASE TELL ME WHAT YOU REALLY THINK (FROM ALL DATA YOU HAVE) WHAT YOU THINK THE WELL or wells are OR WILL BE. Please explain all you have heard or gathered. I do not live in the area. THANKS!!!

Hardage, sorry about that; I interpreted the type of formatin you described as being a good well. I thought if it were thick, it was THERE!!!! I thought that there was very thick shale and so much it would take two. I know that you only have public domain info and make no predictions of your own. What I meant was nothing is said in Joaquin that I can hear. I suppose Joaquin is like Vegas in that way. LOL

adubu -- I am not an expert, only a mineral owner who tries to learn all I can. Further, I do not have minerals in LA or TX, only in OK and KS. The following quote is an excerpt from my notes from the OK-NARO annual conference in May, prepared for my extended family. The session was a panel presentation "New Technologies in Horizontal Drilling". I realize your unconventional formations are probably very different than those in Oklahoma, but I thought this observation might be of interest and stimulate additional comments from those out there with expertise.
"-On the possibility of stimulating older Woodford horizontal wells, a member from the audience asked if, since most horizontals run south to north, could sections be redrilled from west to east? Answer, the natural formation favors almost dead north to south drilling (the Fayetteville shale in Arkansas favors northwest to southeast), then the panelist offered that where the shale is thick enough, there might be an attempt at some time to start the take-off drill path higher (or lower) in the vertical hole and lay another horizontal along the same path, since well bores are perforated and fraced not on the vertical plane but on the horizontal in the Woodford."
Based on presentations at other workshops, seminars and conferences I have attended, my impression is that research is ongoing and empirical evidence is lacking regarding the "reach" of perforation and fracking in these shales, therefore, experimentation and hypothesis testing continues.

Les B---I think what got you and I started off on wrong foot with this discussion was your 1st reply posted on this subject 19 July in which you said multi-frac horizontals are not technically possible for the boosier/haynesville shale. I think we have been on same page but with different colored glasses on and looked at it a little differently understanding what each was saying. Bottom line is same-- Goodrich drilling two lateral legs one in bossier shale and the other I think a little deeper in the Haynesville shale with the R Dean Hays GU #1H and #2H

Adubu, my initial post was to simply clarify the R Dean Hays GU #1H & #2H are two separate wells - not one. By the way, this is already occurring in many areas where operators are drilling both Bossier Shale wells and Haynesville Shale wells in the same unit so not that unusual.
My second follow-on posting was to clarify operators consider the Bossier Shale and Haynesville Shale to be separate formations - not one formation.

Adubu, Les is correct. Though they have not yet started on the #2 well, when they do, they will be two entirely different wells from the surface to TD. As such, the verticals AND laterals will be seperate for each well. One for the Haynesville and the other for the Bossier.

SB---thanks---Les B and I simply ( mostly on my part ) started off with a miscommunication of terminology of Texas vs La. language translation. I am on same page now so look forward to you reporting development as they occur with the R Dean Hays wells. One question will they frac each as completed or wait until both are drilled and then frac both.

SB----do you have any update at the end of this week on R Dean Hays? last week you said TVD and in the curve for lateral leg #1H. Any report on log or gas shows going thru the bossier shale before entering the Haynesville shale formation? AW

SB----do you know if any one has shot 3-D seismic in area of the Goodrich R Dean Hays GU #1 #2 H that they are presently drilling. On the Conference call Goodrich said they had completed lateral of 4800' in the Haynesville Shale. The haynesville was 126' thick with 15% porosity and the Bossier was 188' thick and similar 15% porosity. There where in process of moving rig over on same pad and start the #2H Bossier well also plan 4800' lateral in the Bossier.

adubu, I don't know about the seismic in the area, but I do know that they seemed happy with the porosity in the Hays #1.

SB--what been the average porosity in Haynesville in the good wells over in La.? And do you know about the Bossier wells in Nacgodoches County that EOG has made some Hall Of Fame type wells?

Adubu, generally the Haynesville/Bossier Shale has 8-12 % porosity. Higher rate wells may have more to do with clay content (lower is better) and formation depth.
