Hi John, Damn frustrating trying to use S.I. tonight -- I've had Squid attack after Squid attack. S.I. has sure gone to H--- since they sold !! (The way GNET has been trading, I'd have thought they could install a bit more hardware to prevent that chit!!!!) <<...will the costs be over insurance limits?>>> I have no factual info on that (I've not called IR of any of the companies.). But, when Boots & Coots have been on site as long as they have and given that they've got a relief well drilling around 13,500 feet, I know that they've got to be pushing what would be a "typical policy limit for onshore coverage". <<I assume they were drilling...>> It is my understanding that they were on bottom, 17 feet below the liner, when (I've read somewhere that the ports in the bit plugged and they couldn't pump) it kicked\blew. <<...they would have had core samples (maybe) they would have chips at least. They were familiar with Temblor sand estimated production rates. They were 17 feet from the shoe? maybe 5 feet off vertical and they didn't know what the pressures were in the zone?>> I doubt very much that they would have cored but drill cuttings would have been available. From their mud weight to control the zone before they cased it they'd know the maximum possible zone pressure and I understand that works out to about 18,000 psig, bottomhole. I have no idea how you come up with the 30,000 !!! <<Did they trip after the gas kick, were they tripping?>> No. <<you mentioned they were pumping cement for 50 + days.>> Don't think that's what I said. Read the posts on this thread. Also, read the research reports on the URL that I gave you in my last post What I tried to communicate was that it took them something in the order of 50-55 days (I don't remember exactly) to run the 7" and get a cement job on it and to do several remedial squeezes when the primary job turned out to be less than desirable. <<Where was the BOP?????? Why didn't the BOP work?>> It got "launched" when the well blew. Defective?? Poor weld?? Design fault?? Other?? <<They had had a gas kick just before the blow out, why didn't they mud up?>> They did. But, they couldn't circulate. <<Since Boots & Coots doesn't want to close off the new BOP, I assume the casing is cracked or wore out from sand coming up with the oil/gas.>> Cracked, eroded, embrittled by the fire for the first 10 days and maybe not even designed for the pressure encountered ???? Is that why the first one was launched ?? <<Reservoir damage, there has to be, (depends on fracture zones) Can't see upper casing damage where water would becoming in (sand erosion?)... You mentioned all upper zones where behind casing...>> When the well blew, it blew at rates of 100-130 MMCF/d (rumored). If you check the video at the Bakersfield site you can see at end of that footage that the flare is typical of a dry gas (with ~10 bbls /mmmcf condensate). About a week later, the well reportedly started to make some "steam" and the amount of "steam" increased over a few days until it extinguished the flare and then we had gas, oil (condensate??), water production reported. Since then it seems as though the gas rates have decreased while water rates have increased steadily. I believe the well behavior is perfectly consistent with well coning from the Temblor and NOT at all consistent with water entry from an uphole zone through failed casing. <<How soon before they reach the intersection before they can begin to pump in chickens and cement...>> Getting VERY CLOSE RIGHT NOW. Check the Rogers Research Report on the URL I gave you in my last post for a good schematic of the downhole. <<Guess to many questions Grayhairs, to few answers..>> Yep. <gg> Later, grayhairs
