Don't know if they still use it today but I don't know why they wouldn't unless some better technology has come about.

    The most common cause for blowouts, as far as I know, is because above oil formations it is quite common to find salt domes, or other formations holding gasses under high pressure. Once this formation is "punctured, so to speak, the weight of the "drilling mud" (barite or "bar" as we called it) is supposed to keep downhole pressures downhole. But when the mud comes into a void, and sucked into that void, it can all be lost in a matter of seconds. When methane, or any gas for that matter, rises it expands thus adding additional pressure, overcoming the weight of the drilling mud, this "burping" the drilling mud out of the string of pipe, thus enabling the gas to make it's way to the surface. Sort of a domino effect.

    Drilling mud is constantly monitored for weight and viscosity and return. When the flapper on the return line clicks faster than the mud goes into the hole, you have a problem. It means something is pushing your mud OUT of the hole and you lose the weight holding the downhole pressures down. When you lose your mud return, it means you're losing it downhole. Not a good scenerio either.

    That's when bopper's (Blow Out Preventers or BOP's) are suppose to come into play. You got blind rams and shear rams. Each have their function. They are tested frequently. At least, they supposed to be.

    I worked offshore on J Storm 5 (Marine Drilling) when the gas count registered in the return mud at over 3000 units. We had stand by boats. Daily drills. Used only brass sledgehammers (brass doesn't spark) and absolutely no smoking was allowed.

    It's no place for a screw up. that's for sure.

    Yes, cement is used to set casing. Yes, cement is used to P&A--plug an abandon--a well. But, you know as well as I do that cement isn't used as a plug while drilling operations are going on.

    Last I heard, the BOP stack is tested everytime the rig trips pipe--or, as you say, supposed to be.

    Disparage him all you want, I really don't have a dog in the fight, but he has credentials and his opinion was sought as an expert.



    Also, there isn't a word about Halliburton in the entire article
    He was a pencil pusher that became a teacher. Like I said, those who can do, those who can't, teach.

    He wasn't on this rig, so therefore it's his opinion of what might have happened. On that, he's correct. That is what might have happened.

    There are several applications that are loosly referred to as "plugging the well" using cement. I can't swear to it but I seem to remember using a rubber compund once or twice too.

    Service hands did all that stuff. Schlumberger, Halliburton, National Well Control, etc.

    I just had the pleasure of doing all the floor-hand (read: ****ty work) duties and putting up BOP's and taking them down again and again and again. Back then we used a BFH (sledge) and a hammer wrench. No impact wrenches. Hanging off a ridebelt, above the ocean, torquing up bolts as big as apples, by hand, makes one strong like ox and smart like bull. Wonder if that's why they called us roughnecks?

    I have spent many years in the Gulf. It's a world away from the rest of the world.

    Yes, that is correct. I've seen rubber plugs used, as well. FMC is in the rubber plug business. However, the only time they, "plug", a well using cement is when they are killing the well, permanently. Or, semi-permanently, because I think they can still go back and open a well that's been P&A'ed.

    Service hands did all that stuff. Schlumberger, Halliburton, National Well Control, etc.
    Yessir, along with BJ Services, Franks Casing and Weatherford. I do alotta work for BJ's and Halliburton's cement crews on land rigs.

    Oh come on. That's just the right wing media spin. Everyone knows this is Bush's fault.

    Re: APNewsBreak: Bubble of methane triggered rig blast

    too bad that environmental impact study was cancelled

    washingtonpost.com

    mms' assessments are insulting---a large spill would bleed 1500 barrels total, deepwater disasters would never reach land, would dissipate in 10 days, would dispose "sub lethal" effects on fish...

    it's not just oil, by the way, it's sleaze:

    In 2008, a series of government watchdog reports implicated a dozen current and former employees of the MMS in inappropriate or unethical relationships with industry officials.

    The reports described "a culture of substance abuse and promiscuity'' in the Royalty in Kind program, in which the government forgoes royalties and takes a share of the oil and gas for resale instead. From 2002 to 2006, nearly a third of the RIK staff socialized with and received gifts and gratuities from oil and gas companies.

    You jest, but I did hear a sound bite where some clown was saying that since Bush didn't make the offshore companies use accoustic shut-offs, that it was, indeed, Bush's fault.

    I saw Bob Beckel on Hannity Monday night going on about how it's Halliburton's fault. Plus we have that silly thread about how it might be Halliburton's fault. I knew it would get rediculous as some point; just didn't think it would take so long...lol

    Purdy much how they do it now.



    Where'd you leave out of? Fourchon? Venice? Cameron? Freshwater City? Intracoastal City? Morgan City? Berwick? Port Lavaca? Port O'Conner? Harbor Island? I've poured sweat in all of'em...
    Right on brother. You ****ing rock. We WILL drill!

    When I was with Marine Drilling, we flew outta the Corus Christi Area. When I was working with Penrod, I would catch the helo outta, I wanna say, Leevilles, Leesville, LA??? We could see Venice lights at night. It was at the Chevron yards, I believe.

    When I was doing completions, (setting slips, inspecting well-head installations, testing annulus's (sp???) for National Well Control, I would catch outta wherever the hell they sent me. I've done Cameron, Intracostal City, Morgan City and Port Lavaca for sure. Port O'Conner rings a bell but Harbor Island and Berwick does not. But maybe... you never know. That was 2 decades ago.

    I also worked a lotta land rigs in the Austin Chalk near Giddings, La Grange, (they gotta lotta nice girls..sahh..) Texas area. Also worked on some doubles and triples, land rigs drilling and doing some workover throughout Texas. Also dod a butt-load of completions on land rigs for NWC in the chalk.

    I got scars bro. By now, you probably know that to be true having worked the patch yourself.

    Keep turnin' to the right.
