Monday's intriguing people

Eric Sheptock
The D.C. homeless man is using social media to advocate for other homeless people. He says he got a leak fixed at one homeless shelter and stopped harassement of homeless people at another. Using computers at libraries, Sheptock communicates with nearly 1600 e-mail contacts, 5,000 Facebook friends and hundreds of Twitter followers. He has two blogs and a Facebook fanpage. Sheptock says he's now trying to use his popularity to start a movement that reduces homelessness and improves shelter conditions. Read the Washington Post's story about Sheptock. His story is not without its critics.

Oskar Schindler
A New York judge has allowed a memorabilia collector to sell what the collector is saying is the original "Schindler's list." The Telegraph reports that the list is said to contain the names of more than 1,000 Jews that Oskar Schindler saved during the Holocaust. There had been a ban on sale of the list, according to The Jerusalem Post. The paper reported that an heir to Schindler's widow previously tried to prevent selling the list.

Blizzard stranded blogger
For every stuck traveler, your voice was heard Monday through the clever tweets of one of your brethren, Jason Cochran (@bastable). Cochran was, at least as of this posting, among the hundreds of passengers stranded at JFK Airport in New York which closed due to blizzard conditions. He tweeted that he was there for more than 17 hours including four hours in a plane on the tarmac waiting to fly to London. is reporting that Cochran's tweets began at about 8 p.m. ET Sunday night.

    Fred...the pressure isn't on the inside of the drill pipe. We have a "check-sub" directly above the drill bit. I's a one-way check valve, so when you drill into a high pressure zone, no pressure can force cuttings up inside the drill collars. The deepwater horizon rig drilled into a gas pocket with such high-pressure, it literally lifted an entire 18,000 ft. of pipe 60 ft. I've seen entire string of pipe blown out of a hole before. It comes sickleing out of the hole skyward, and scatters like a long string of spaghetti. (it was a 9,000 ft. well drilled by the Cardinal Drilling Corp. on top of Douglas Pass near Grand Jct. CO. round about 1979) Even when the BOP does it's job, you stil need the casing cement to do it's job in order to keep hydrocarbons from escaping the wellbore.

    Fred, and I think you are referring to annular pressure. This is the pressure found between the well bore and the drill pipe. We drill holes in stages. We might drill a few hundred feet of say 24inch diameter hole, then set casing and cement the casing pipe to the wellbore. Then go and drill a few thoudand feet of a smaller diameter hole, and so-on and so-forth. By the time we TD (reach total depth) at say 20,000 feet, our hole diameter would be like 6and1/4 inches. With each reduction in hole diameter, we "run pipe"...set casing pipe and cement it to the wellbore.(after we have tripped, or removed our entire drill string and stand it in the derrick in 90 some foot sections) Each of these surface and intermediate casings are held in place by cement. If the cement doesn't hold, hydrocarbons can escape.
