Explore new collaborative ways to find oil easier


Oil and gas wells are ever more difficult to find. To minimize the risk of drilling "dry holes" the interpretation of seismic data becomes more and more important and is getting increasingly complex with the vast amount of data being available from subsurface sonic measurements. The principal method geologists use to explore subsurface, besides the direct and expensive drilling, is with sound waves. The subsurface geology of prospective basins is mainly reconstructed from 2D seismic images, assisted by detailed information from any nearby wells or outcrops displaying the same sequences. The geological reconstructions are then used to identify potential traps and to assess how likely they are to contain hydrocarbons - and if so, if there is a sufficient quantity to justify drilling.nVidia
Well planning is done with appropriate visualization tools. Visualization tools are software applications which visually convey complex three-dimensional information in an intuitive fashion. Ideally these tools engage as many of the visual cues used in perceiving the 3-D world as possible. This is the place where the VRGeo Consortium, which is a consortium of the international oil and gas industry, steps in. Its main goal is the development and evaluation of interactive hardware and software technologies for visualization systems in the oil and gas industry.
After discussions with the VRGeo Consortium members, the VRGeo R&D team at Fraunhofer IAIS developed a prototype application for the collaborative interpretation of 2D seismic data using multi-touch tablets. The system was designed to allow multiple users to simultaneously annotate and interpret seismic data and display the result in real-time on a large cylindrical display system called i-Cone. The system supports an arbitrary number of participants and the tablets used were driven by the powerful NVIDIA® Tegra™ 2 chip running on Android OS.
i-Cone uses surrounding screens which enhance the degree of immersion, compared to flat screens. They are curved to create a seamless transition of the projection field, and to reduce the visibility of perspective errors resulting from observer positions away from the centre of projection. The projection system is driven by a HP workstation using a NVIDIA QuadroPlex solution to drive the 4 Barco projectors in a SLI Mosaic configuration.
Each seismic interpreter does have his own seismic interpretation workspace on his individual tablet PC with individual seismic interpretation results. In order to discuss these results in a joint workgroup meeting, each individual workspace can be combined and displayed in the i-Cone. With this real collaborative seismic interpretation becomes possible. The times where seismic interpreters had to rely on an operator in the background or did exchange their results through PowerPoint slides are over. "The demonstration of the system and the collaborative scenario received a very positive feedback with the possibility to allow equitable interaction amongst all participants in particular." says Manfred Bogen, VRGeo Consortium Programme Director at Fraunhofer IAIS in Sankt Augustin, Germany." The removal of a single operator during collaboration was rated extremely beneficial with respect to the engagement of all users. These observations suggested that multi-touch Tegra tablets have the potential to fundamentally change the way we collaborate."
The next steps in this project will include the evaluation of 2 other suggested scenarios and discussions with the experts in the O&G domain, like Eni, ExxonMobil and Landmark Halliburton, on how to integrate the system into their daily work.

'Star Trek II' producer talks Ceti Eel, J.J. Abrams, and more (Q&A)

Robert Sallin, producer of "Star Trek II: The Wrath of Khan," shares his experience working on the film, looks at the future of "Trek," and dishes on whether that was Ricardo Montalban's real chest.

The release of "Star Trek Into Darkness" has not only spurred interest in the "Trek" world in general, but especially in its film daddy, the original Khan-as-villain movie "Star Trek II: The Wrath of Khan." While the new film takes quite a few detours, it is full of homages to the earlier work. Let's look back to 1982. "Star Trek: The Motion Picture" had been released in 1979 and faced a poor critical reception. Paramount, the film's studio, was gun-shy after the movie nearly doubled its original budget, ending up with a $46 million price tag. Nonetheless, plans for a second movie plodded along. It's 30, 40 years later and we have new audiences. You can't keep dwelling on the old guys and the old things. It has…

Best tech gifts under $100 for Dad

Roku's speedy streamer is the best box yetThe good:The Roku 3's excellent new interface and faster processor makes it feel quicker and more responsive than any other streaming box. More than 750 channels are supported, including Netflix, Amazon Instant, HBO Go, Hulu Plus, Pandora, MLB.TV, Amazon Cloud Player, and Vudu. It also has cross-platform search that scours several major TV and movie services to find content. And Roku's nifty new remote has a built-in headphone jack that lets you listen without disturbing others. The bad:There's still no official YouTube channel. Some services have an outdated interface on Roku compared to other streamers. The Apple TV still works better within the Apple ecosystem. And the Roku 3 isn't a great option if you're mostly looking to stream your personal digital media collection. The bottom line:The Roku 3 is the best streaming-video box yet, with tons of content sources, lightning-fast performance, and an innovative remote wit…

How to boot directly to the desktop in Windows 8.1

The Windows 8 Start screen is a good starting point for Windows 8 devices with touch screens, but on PCs with standard screens, you might prefer to boot directly to the desktop. Previously, you could bypass the Windows 8 Start screen with Start8, but Windows 8.1 now lets you do it natively. Here's how:
Step 1: Right-click on the Windows 8.1 taskbar, then choose Properties.
Step 2: Click on the Navigation tab, then under the Start screen section, check the box next to "Go to the desktop instead of Start when I sign in."



The next time you boot Windows 8.1, you'll go straight to the desktop without ever seeing the Start screen.
