O ver the last 25 years, a series of studies has investigated the diurnal formation and destruction cycle of temperature inversions in valleys and basins (for a review see, e.g., Whiteman 1990). In most of the valleys and basins that have been studied to date, advective influences produced by the well-known, diurnally reversing upand down-valley wind systems have greatly complicated the analyse...

We integrated new and existing geological, geochronological, thermochronological, two-dimensional (2D) seismic data from the Salar de Punta Negra Basin to define Late Paleozoic–Cenozoic tectonic evolution of inner Andean forearc northern Chile more precisely. Our results indicate that this region experienced early Paleozoic–Mesozoic crustal extension, creating several basement half-graben struc...

An experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, CCl4/water, toluene /water + glycerol (25 % wt), toluene + CCl4 (25 % wt) / water and toluene / acetic acid (5 % wt)/water. The effects of physical properties, mass transfer and column geometry...

The spatial position and dip feature of the density boundary are significant to study fault tectonic frameworks. Edge detection methods generally attach importance horizontal boundary, but it is difficult determine expressly. A gradient inversion method was proposed based on corresponding relationship among gravity forward field, kernel matrix, model attributes. result this that value different...

Abstract Sedimentary successions exposed at basin margins as a result of late-stage inversion, uplift and erosion usually represent only limited portion the entire fill; thus, they are highly incomplete records evolution. Small satellite basins, however, might have potential recording more complete histories. The late Miocene sedimentary history Șimleu Basin, north-eastern vast Pannonian was in...

generally, the measured secondary field data is inverted into resistivity using two principal models; the homogeneous half-space model and the layered half-space model. while the homogeneous half-space inversion uses single frequency data, the inversion is done individually for each of the frequencies used, the multi-layer 1d inversion is able to take the data of all frequencies available into ...

Abstract The upper Assam shelf is a self-slope basin in north-east India, filled with nearly 7 km of sedimentary rocks tertiary period the granite basement and various oil fields along border Naga thrust. major producing are structural strati-structural. study area placed between Mikir hills objective to identify potential hydrocarbon reservoir zones geologically complex south using estimates a...

We present an integrated method for mapping the basement structures of sedimentary basins by combining surface gravity data, seismic imaging, and borehole logging information. The core is a nonlinear inversion algorithm constructing shape depth from data. By using primal-logarithmic barrier method, we impose constraints was imaged interpretation incorporated into as reference model. As result, ...

Synchronous prestack inversion technology has been widely used to predict the fluid and lithological properties of reservoirs. Its prediction accuracy depends on seismic data quality. Ultra-deep carbonate reservoirs in Shunbei area Tarim Basin were as research objects. Based shear wave (S-wave) method, petrophysical logging analysis was carried out select physical property-sensitive elastic par...
