Halliburton has recently made upgrades to its formation technologies for more extreme downhole conditions of temperature and pressure. The company’s new Hostile Sequential Formation Tester II (HSFT-II) tool allows operators to evaluate formations at pressures and temperatures up to 30,000 psi and 450°F, respectively, and in boreholes as small as 4 in., an industry first for formation-testing tools.
The new HSFT-II retains many of the same features of the first-generation HSFT, including the ability to acquire formation-pressure data and fluid samples in unconsolidated formations and H2S environments. Like the original tester, the new tool permits slimhole formation testing and sampling and navigates difficult hole conditions such as restrictions and high dogleg severity.
However, the new tool extends the operating environment to even hotter and higher-pressure formations, and operators are taking notice. In June 2009, Halliburton evaluated Shell’s Rashda A1 well in Libya with its high-pressure/high-temperature wireline logging suite and the HSFT-II tool to acquire downhole formation pressures, at temperatures reaching 420°F—a first for Shell—and pressures of approximately 20,000 psi.
Normally, drilling would be essentially blind under these hostile conditions, calling for the low-risk option of setting an intermediate liner to prevent formation damage, at considerable cost with associated nonproductive time, Halliburton says. The new formation tester allowed five pressure points to be successfully acquired, which revealed that the drilling operation could continue with minimal risk of a blowout, saving time and money.
“The Rashda A1 pressure data was successfully collected at the highest temperatures ever attempted by Halliburton and provided the customer with very valuable information in the most difficult of downhole conditions,” said Jonathan Lewis, vice president of Wireline and Perforating, a Halliburton product service line.

I completely agree with James here, this has got to be the loegsnt developed vaporware of all time. You guys are starting to rival Duke Nukem. And your updates are getting comical, you are posting stuff over the course of weeks that should take a day for someone to put out that's working on an indie team or a mod much less an actual studio. I can't believe I am still coming back here. I remember when you guys used to post screenshot's of your game I still played SM Gettysburg then. I think I lost hope between the first and second Take Command games came out. And dang, since then there is now Scourge of War: Gettysburg. All three of those games by the same guy and his slowly growing team. Honestly, this feels like a fake project. Yet, it has been going on so long I figured you guys would have given up on the joke by now. And here it is, still kicking. Why don't you take an approach like Notch, with Minecraft(selling a game before final release, giving free alpha/beta updates at a reasonable pace)? It would lend some credence to your cause by giving us something tangible. And on top of that getting a little money out of some interested customers might just spur you people to actually commit some time to this and make a game or hire people to do it for you rather then just showing off a little tech demo every few months.

C'est parfait de uivpoor former nos jeunes comme cela. il faudrait aussi mettre en place des formations de techniciens pour que nos garagistes puissent entretenir et re9parer nos voitures e9lectriques

The only sound heard was that motocycle hmmm, so weondr why the debunkers aren't telling you those are just airplanes ..since there wasn't any sound from the sky it's really bold to say, but I thought I saw a triangle.
