BJ Services is the company that is supplying the pumping units, and 10 of them adds up to about 13,000 Horse Power. This is what was relayed to me. In Bob Christy's news article to come, we'll get to see his photos from the air. He said he took 3 rolls of film. I'll try to purchase some photos for the Eland Jennings web site.

Hi Poseidonas, Yes, from what's been posted on this thread and from what my source tells me, they should be ready to make their kill attempt tomorrow. To answer your question as to how long it will take, I very seriously say hopefully only a couple of days but potentially a month. I've never had to kill even a shallow blowout in a "conventional reservoir" let alone an awesome well like this but I'll try and describe for you what I imagine would be the main steps of their kill program. Drilling engineers that may be lurking, please do forgive me !!<gg> First, I am assuming that you are familiar with the Peters & Co schematic posted on the Eland Jennings website. If not, you probably should browse it before continuing here. With the pumping units on site this afternoon I expect that everything will be completely rigged in tonight. After pressure testing all surface equipment and flowlines and holding their morning safety meeting they should be ready to attempt the perforating. Hopefully the perforating gun(s) fire with no hitches but do recall that this equipment is subjected to some rather uncommon and harsh conditions (~15,000 psi pressure and ~330 degrees F.) so don't be too surprised if..... If the guns do fire as intended, will enough perforations actually strike and penetrate through the 7" liner to establish the required flow capacity for the injection of kill fluids ?? After perfing, they'll have to run some sort of an injectivity test to ensure that they've got all the injection capacity that they need. If not, they will have to repeat the perforating procedure (or perhaps perform an equivalent abrasive jetting operation), so don't be too surprised if..... When they do have adequate flow capacity established between the two wellbores, they'll start pumping\injecting a very dense mud to attempt to choke off the current flow of lighter fluids and to counter the ~15,000 psi reservoir pressure with the "weight of the 17,200 foot mud column". When this step is successful, the well will be under control but the crews won't be able to head off for holidays just yet !! They'll have to first displace the mud column out of the #1 well by circulating (i.e. pumping) cement to replace the mud. After they have established good cement returns at surface, they'll shut in the wellhead. But they'll maintain plenty of pressure on the injected cement so as to "squeeze" as much cement into the #1 well as they possibly can. Cement additives will control the "set time" for the cement and they'll maintain the pressure on the cement until the cement should have set. Hopefully at that point the kill will be complete, but don't be too surprised if..... After completing the above, they'll be on a close look out for evidence of gas or elevated pressures in the relief well or at the wellhead of the #1 well. They'll undoubtedly do a pressure test to see if they can hold pressure within the wellbore of the relief well or if they have injection through the supposedly cemented perforations. Hopefully the pressure test holds. If not, they'll have to "clean out" the relief well to TD and undertake remedial work. That work would involve more perfing, more pumping mud, more cementing, etc. If the pressure test does hold, as we all hope and pray it will, they'll fill the lower portion of the relief well with cement and commence the replacement well kick-off from about 10,800 feet. These later activities will however only commence after the "kill" party !! <gg> Hope this helps you picture the primary steps in what the oil patch describes with one word as a "kill". Have a pleasant evening. Later, grayhairs
