A low-cost method is proposed for evaluating the degree of compaction in reservoir rocks by using automatic inference methods on optical photomicrographs. In order to reproduce the visual interpretation performed during petrographic analysis, a hybridmethod was developed combining image processing algorithms with knowledge representation and reasoning models. The method proposed was inspired on visual attention, the mechanism used by the human brain for dealing with visual information. This m...

Automatic Detection of the Degree of Compaction in Reservoir Rocks Based on Visual Knowledge
Posted on October 17, 2009 by ENDEEPERTackling complex reservoirs through systematic petrographic Characterization
Posted on October 17, 2009 by ENDEEPERDespite the spectacular advances in seismic and log acquisition and interpretation, and in 3D and 4D modeling, the risks involved in the exploration of new, deeper, depositional, tectonic or diagenetically-complex prospects remain large. This, essentially because these sophisticated methods simply lack information on an essential part of petroleum systems: the reservoir. Most new prospects represent clastic or carbonate rocks with strong diagenesis. For these, the conventional, indirect evid...
Diagenetic Processes in Sabkha Deposits and Exploration Potential of the Intracratonic Parecis Basin
Posted on October 17, 2009 by ENDEEPERThe Parecis Basin is a large intracratonic basin in western Brazil, with more than 6 km os sediments. The petrologic study of the Paleozoic Pimenta Bueno Formation in the PB-01-RO drill core revealed the occurrence of sabkha deposits, in which playa lake evaporites are interbedded with fluvial sandstones. The diagenetic processes observed in these rocks are largely facies-controlled. The evaporites show early silicification of originally microbial, micritic mud, followed by extensive replacem...
The Concept of Deionized Water
Posted on July 19, 2009 by joalestoDeionized water contains no minerals and ions. Home equipment for this process uses the common water-softening method that takes away calcium and magnesium ions causing stability. The industrial deionization process is a little more complex, removing all negative and positive ions completely. Deionization is said to rob water of useful minerals, but nearly all professionals argue that water purification guarantees safer water.
The Rumors Concerning Drinking Deionized Water
Posted on July 14, 2009 by joalestoDeionized water has been attacked by disputes which claim it is unsafe because it is "too pure." This is ridiculous though. Water is filtered and deionized to eliminate harmful agents and to make water as safe as possible for consumption and other household applications. DI water does not deprive the body of nutrients and minerals. Moreover, its nutritional value is neither better or worse than mineral water.
Application Of Innovative Laser Research Could Lead To Earlier Bone Disorder Diagnosis
Posted on July 11, 2009 by Shane EA new laser technique that could lead to bone disorders being diagnosed earlier is to be tested in a hospital for the first time. The study, which it's hoped will pave the way for future clinical trials, will apply a revolutionary approach known as SORS (Spatially Offset Raman Spectroscopy), to examine specific substances in non see-through surfaces deeper than has previously been possible, without damaging the surface.
Military Looks to Stop Drivers With Laser Blasts
Posted on July 11, 2009 by Shane ELaser dazzlers — or “optical distraction devices,” as the military prefers to call them — have proven invaluable in Iraq as a way of warning drivers to stop at checkpoints. (A flash of bright light does tend to give people pause.) But as Danger Room reported, several U.S. troops have suffered serious eye injuries from laser “friendly fire” incidents.
The Airborne Laser is an Important Part of America’s Missile Defenses -- Tests Prove It
Posted on July 11, 2009 by Shane ELate this spring, there was a successful in-flight test of the Airborne Laser (ABL) tracking system. Despite this, there is a common misperception that the ABL is an experimental defensive weapon that has no practical use.
Experts See Divergent Futures for Boeing's Two Flying Lasers
Posted on July 11, 2009 by Shane EFor years, the Pentagon's research budget has funded not one, but two planes armed with laser turrets. Although the Airborne Laser (ABL) and the Advanced Tactical Laser (ATL) have different missions, both projects are led by aviation and defense giant Boeing, and both consist of a chemical laser mounted on a large aircraft.
Lasers can lengthen quantum bit memory by 1,000 times
Posted on July 11, 2009 by Shane EPhysicists have found a way to drastically prolong the shelf life of quantum bits, the 0s and 1s of quantum computers. These precarious bits, formed in this case by arrays of semiconductor quantum dots containing a single extra electron, are easily perturbed by magnetic field fluctuations from the nuclei of the atoms creating the quantum dot. This perturbation causes the bits to essentially forget the piece of information they were tasked with storing.

High Tech meets High-end Cuisine
Posted on November 28, 2008 by Crystal CampbellThere's a new movement heating up the culinary scene: high tech cooking, also called molecular gastronomy. For many decades California Cuisine has thrived, with its focus on fresh, local, organic ingredients. Now chefs are focusing on a need for attention to preparation as well, and they are using scientific techniques, tools and exactitude. High-tech is now enabling greater results in high-end cooking.
What's Inside Darpa's $21 Million 'Liquid' Laser?
Posted on December 31, 2008 by Shane EThings are really beginning to heat up in the field of laser weapons. The giant Airborne Laser is finally gearing up for real-life, missile-zapping tests. New solid-state lasers like Raytheon's Phalanx can already shoot down mortar rounds.
Full moons
Posted on May 25, 2009 by Aura MirchandaniThe full moon represents a lunar phase when the moon lies on the opposite side of the Earth from the sun. The moon, when it is full, can be seen in full light reflecting off of the sun. This is only half of the moon as the dark side of the moon is on the opposite side. There was an American space shuttle named Galileo that took an infrared composite image of the moon on December 7th, 1992 while it was on its way to Jupiter. These images are shown on a few scientific websites. A lunar eclip
Math Tutoring – Is It In Your Cards?
Posted on May 25, 2009 by Aura MirchandaniDo you have a child that is having trouble with math in school? Are they becoming frustrated and non responsive to the subject? Or perhaps you yourself are having trouble with some of your university math classes. Math tutoring – is it in your cards? It’s a great way to get the help you need!
