The article is devoted to the outlook for oil and gas potential of Mesozoic complex Terek-Caspian downfold. problem content great depths has been interest scientists specialists since ancient times. However, it became especially relevant in second half 20th century. With depletion Miocene deposits Tersko-Sunzhenskaya region being exploited a long time 50s century, question preparing new hydroca...

Tutorial dialogue has been the subject of increasing attention in recent years, and it has become evident that empirical studies of human-human tutorial dialogue can contribute important insights to the design of computational models of dialogue. Students with particular characteristics may have specific dialogue profiles, and knowledge of such profiles could inform the design of tutorial dialo...

The Cambrian Mt. Simon Sandstone (MSS) is a possible unconventional gas reservoir in the Illinois, Michigan, and Appalachian Basins, but comparatively little is known about the unit. This study used core and well logs from two deep exploratory wells to interpret the depositional environment of the MSS under western Ohio, where the MSS is about 120 m thick and found 1060 m below ground surface. ...

A new 3D/2D interactive display server was developed for the IGeoS geophysical data processing framework presented earlier. With introduction of this major component, the framework becomes conceptually complete and potentially bridges the gap between traditional processing and interpretation geophysical software. The display server utilizes Qt toolkit and OpenGL graphics libraries while taking ...

Both geophysical and geochemical techniques contribute to our understanding of the complex nature of the Earth’s mantle, but the two sources of information provide very different viewpoints. Most geophysical evidence provides an instantaneous snapshot of current structure, whilst geochemical evidence has much more information on age. Further, geophysical probes are naturally integrative since t...

We present a short atlas illustrating the unusual Ca ii K-line profiles in upper main sequence stars with anomalous abundances. Slopes of the profiles for 10 cool, magnetic chemically peculiar (CP) stars change abruptly at the very core, forming a deep " nib. " The nibs show the same or nearly the same radial velocity as the other atomic lines. The near wings are generally more shallow than in ...

Hyperspectral sounder data is used for retrieval of atmospheric temperature, moisture and trace gases profiles, surface temperature and emissivity, cloud and aerosol optical properties. The physical retrieval of these geophysical parameters is a mathematically ill-posed problem whose solution is sensitive to the error or noise in the data. Therefore, lossless or near lossless compression of hyp...

A field experiment consisting of geophysical logging and tracer testing was conducted in a single well that penetrated a sand-and-gravel aquifer at the U.S. Geological Survey Toxic Substances Hydrology research site on Cape Cod, Massachusetts. Geophysical logs and flowmeter/pumping measurements were obtained to estimate vertical profiles of porosity phi, hydraulic conductivity K, temperature, a...

various sources of geodetic, geological and geophysical information can improve our understanding about the crustal density. in this paper we propose a methodology for determination of crustal density based on terrestrial gravity observations, geopotential models, digital terrain models (dtm), geological maps and cross-sections, deep geophysical profiles, and geoid models. the method can be alg...
