New model of geological strata may aid oil extraction, water recovery and Earth history studies
May 23, 2012 • ALBUQUERQUE, N.M. — A Sandia modeling study contradicts a long-held belief of geologists that pore sizes and chemical compositions are uniform throughout a given strata, which are horizontal slices of sedimentary rock. By understanding the variety of pore sizes and spatial patterns in strata, geologists can help achieve more production from...

Cyber workshop at Sandia Labs seeks potential responses to cyberattacks
October 25, 2011 • ALBUQUERQUE, N.M. — Among other dubious achievements, hackers have stolen identities, broken into bank accounts and breached computer systems of military contractors. They could conceivably interrupt water or electricity service to targeted populations. And worse. To solve these problems, Sandia National Laboratories has plans to increase cybersecurity research over the...
