Comment only going to get worse... (Score 5, Informative) 375

Most utilities are moving to smart meters. It's a technological nirvana propounded by PHBs and the companies selling the crap. Just think, you don't need to waste hard cash on people actually reading meters. Hell no, you can drive down a road and read all the meters with a laptop. Except you can't because some of the technology is immature and signal strength from these devices seldom reaches the manufacturers claims.

We were told by a manufacturer that their technology was secure because their software is proprietry. It's a recipe for disaster...especially given that a quick google for "security research smart meter," returns some interesting results. Welcome to the brave new world of smart metering. Minus the "smart."

Comment *nix, backup and storage certs (useful to a point) (Score 1) 444

As deblau stated, "What kind of job do you want?"

If you're applying for a Solaris & EMC shop, look no further than your Oracle Solaris certification and EMC backup/storage track. However, the certification only demonstrates that you can attend a testing centre and answer questions based upon specific scenarios or a subset of your knowledge. What you really need is experience (I know, chicken/egg,) a willingness to learn and an employer that's willing to invest in you (and not offshore your job to a heavily certified, but functionally useless graduate in Hyderabad.) YMMV.

Rant.

How about listening devices planted in flowers sent to the bereaved? The UK's tabloid press have been out of control for years. This isn't about press freedom, or even freedom of speech or expression. It's about Murdoch's agenda, gutter journalism and selling salacious crap to any window-licker that'll buy it.

We can hope that his sorry newsprint empire will wither like his online presence behind its paywall. Sadly, that's not going to happen...not for as long as the unwashed want innuendo on the front page, reactionary crap on page two and hooters on page three. It may be tomorrow's fish and chips wrapper, but it has already peddled its sordid agenda by the time some fat-ass is chomping his way through the deep fried goodies it contains.

Tabloid journalists and their paymasters? I shit 'em.

End rant.

I think you've possible conflated drilling and production. I can accept that I may have misread your initial comment, but you seem to infer that the stack is used during production. That wasn't the case in the Macondo well (although it's commonplace during wildcat DSTs...which this most certainly wasn't.)

The semi-technical answer is rapid, uncontrolled sand flow pretty much destroys the pipes and other down hole stuff. It would be way faster and cheaper to drill a new well than to repair this one. Its sort of the difference between duct taping something together in a movie plot therefore its possible vs actual business operation. What I'm getting at is testing and certifying casings and hangers and parts is really cheap when its on the surface, and really expensive when its buried in the earth.

I'm not sure I entirely agree with any of this. Firstly, sand control can be an issue...but it's commonly felt at the surface (pre and post-separation.) Secondly, sand is semi-controlled via flow rate. You don't open the well to atmosphere during production - you use an adjustable choke. If a well produces a lot of sand, then surface sand filters are deployed. Thirdly, drilling a well is far more costly than a workover (where one replaces the production string.) Lastly, testing pressure control equipment happens at the surface as part of manufacturing QA, but it's also tested in the hole - where it really matters. The cost of surface and downhole testing is not relevant.

is there any GOOD reason why they simply didn't repair the blowout preventer, hook up a new dipstick, set up a new rig, and keep on a-pumpin'?

The BOP isn't used for production, only drilling. After a well has been completed (i.e. a string of production tubing has been run,) the stack is removed and replaced with a subsea tree. This is the device that controls well production long after the drilling rig has moved.

"Drilling fluid" used to take pressure measurements might be purified water, which idiots might wave away because it costs money and they have tons of money.

Er, drilling fluid is a thixotropic fluid used to carry cuttings to the surface, lubricate, cool, support the drill string and exert a hydrostatic head. It can be water-based or oil-based (effectively an oil/water emulsion.) The list of additives is as long as your arm and designed to meet the engineering requirements at any point in the drilling phase. It'll usually be circulated out prior to abandonment or pre-production completion.

Comment Re:Seawater Vs Drilling Fluid (Score 1) 181

I'm no drilling expert. I read the articles (but not the whole report) and, as the submitter, I guess I failed to explain that the articles seem to imply that at some point it's okay to switch from drilling fluid to seawater when the rig is recognized as very stable

Displacing a well to seawater is not at all uncommon and is done for a variety of reasons - it's not a gamble. In this case, had the crew spotted returns from the well a little earlier, they would have controlled the kick that became a blowout.
