New and game-changing developments in geochemical exploration

Application of Geochemical Methods in Geothermal Exploration

Subsurface waters have been classified into meteoric water, ocean water, evolved connate water, magmatic water and juvenile water. Geothermal water is mostly meteoric and oceanic water although andesitic waters near subduction areas often contain significant proportions of evolved connate and magmatic waters. Geothermal waters have been classified with respect to their anion and cation contents...

New developments in conventional hydrocarbon exploration with electromagnetic methods

Over recent decades, electromagnetic methods have been viewed with considerable suspicion by many in the hydrocarbon exploration industry. While highly effective in mineral and environmental geophysics, electro m a g n e t i c methods have played a minor role in hydrocarbon exploration. Since electromagnetic (EM) methods use signals that diffuse in the Earth, they cannot provide the same vertic...

Some New Developments in Small Area Estimation

Small area estimation has received a lot of attention in recent years due to growing demand for reliable small area statistics. Traditional area-specific estimators may not provide adequate precision because sample sizes in small areas are seldom large enough. This makes it necessary to employ indirect estimators based on linking models. Basic area level and unit level models have been extensiv...

Game-Changing Tools and Practices

September/October 2010 www.stsc.hill.af.mil 5 S analysis tools (see the sidebar on page 7) are very useful for finding bugs. They go far beyond the capabilities of compilers (warnings) and coding standard checkers to which they are directly related. Like compilers when they generate warnings, static analysis tools aim to detect possible run-time errors (e.g., buffer overflow) and logic errors (...
