JL. For once, I agree with you. Okay. Let me explain the situation to the best of my ability. The well has extinguished itself, and it likely IS Temblor water, that underlies the oil\condensate\gas column we have seen being produced for the last 2 weeks. It looks like what happened is that the well has "coned out", meaning that there has been such a large negative pressure on the formation around the well, due to the sudden exit of a lot of gas, that fluids have been drawn in to fill the void, water being the densest and therefore the last to appear. We know that the first gas kick occurred at approximately 16,300 feet, some 1350 feet above our current position. We know that they were producing hydrocarbons the entire time they were drilling from 16,300-ish feet to 17,660 feet. There was no sign of water. We know that they lost the drilling mud from the wellbore, whilst drilling, two months ago, at 17,640 feet (+/- 10 feet). They then regained control of the well and ran a string of casing (9 5/8" casing, I think). We know that they drilled just 17 feet of new formation before the well blew out and created this mess. We know that the well produced a minimum of 100 million/day and 1000 bbls condensate/day for 2 weeks, unrestricted. What I suspect we have is a monster gas reservoir (3TCF is still conservative), at least 300 vertical feet thick and potentially 1300 feet thick. I think we have drilled through the gas column and set pipe in, or just above, the oil layer. There is a marked drop in the pressure gradient as you go from one to the other (a fluid characteristics thing), not to mention a drop in pressure with depth as you drill away from the "overpressure" situation created by the thrust-fault. This is how I think the blowout occurred. We know they had weighted up their drilling mud significantly, to counter the gas pressure, but on entering the denser phase became overbalanced, lost their borehole fluid column (thus becoming severely underbalanced) and had the gas come in on them. This is just my opinion, but it makes absolute sense. Feel free to bandy it about with any oil-types you know. I'd like to hear if my argument is flawed. In short, I think we are in great shape, geologically. Financially, the markets will probably react in a negative way. It will take time to assess things, and to drill Bellvue #2. Speculation will run wild for a time. The potential is definitely there for ELH to go sky high yet. I hope this helps rather than confuses. Regards, Rick.
