NASA successfully launched the world’s latest earth-observing satellite aboard an Atlas V rocket from Vandenberg Air Force Base in California today, crystallizing hopes that US scientists will be able to maintain and enhance a continuous environmental monitoring record that dates back more than four decades. NASA and the US Geological Survey are expected to initiate the launch at 1:02pm EST from California's Vandenberg Air Force Base. Once it's in space, Landsat 8 will collect photographs, thermal data, and infrared images from 438 miles above the surface of the Earth, circling the planet roughly every 99 minutes or 14 times a day. On each pass, the satellite will capture a 185-kilometer-wide section, giving us a full image of the globe once every 16 days. Though it doesn't provide the incredibly high-resolution imagery you'll find in some satellite photos, it gives scientists, businesses, and the public (since the data is released for free) a look at what's going on across the planet, showing us environmental changes or the spread of cities and farmland.

Here another trick to inport Shp file into petrel with Xtools Pro http://forums.arcgis.com/threads/12362-ArcGIS-to-Schlumberger-Petrel-format Untill ESRI supply a plug-in allowing free movement of shapefiles from Arc into Petrel I have been using XPro Tools to export shapefiles into Petrel via text files (ASCAII files): For polylines (in a file geodatabase) I have converted the vectors into points using the ArcMap Tool drop down menu and selecting convert to point. Then I aadd X,Y (Z if needed) data by using XPro Tools Table Operations, which can be viewed, once the operation is complete, in ArcCatalog or the Attribute Table, the tool gathers XYZ co-ordinates for each points and adds them to a table. Then using the XPro Tools convert the Point Shapefiles into Text files by using the 'Table Operations' > 'Export Table' to Text menu to convert all the points into a text file/or you can use excel spreadsheet (BTW this will accept any data in the attribute table), which can be imported into Petrel using Irap classic lines or points or Zmap point imports. But if you have the plugin i can easly patch the signature......
