In the Bulgarian Black Sea shelf, several gas fields have been discovered in Maastrichtian–Paleocene sediments to date. this study, amplitude versus offset analysis (AVO) was carried out, and extended elastic impedance (EEI) also used, predict fluid lithology properties. Thus, these special cases, AVO (or reflection angle) can significantly de-risk existing Paleocene prospects allow focus on Mi...

Database management technology is central to the development of the Virtual Observatory (VObs), since its eventual aim is that the worlds astronomical data collections should look like a single large distributed database. Relational database management systems (DBMS) are good at searching through large tabular datasets such as source catalogues, but the important operation of cross−matching sou...

The seismic reflection characterizations of a thin layer are important for reservoir geophysics. However, discussions on the reflection for a thin layer are usually restricted to precritical angle incidence. In this work, an exact analytical solution is derived to model the reflection amplitude and amplitude variation with offset (AVO) responses of a single thin bed for arbitrary incident angle...

The question whether chemotherapy-induced autophagy is causative to the demise of the cells or a part of the survival mechanism activated during cellular distress is unclear. Others and we have previously demonstrated apoptosis-inducing capacity of N-(4-hydroxyphenyl)retinamide (4-HPR) in malignant glioma cells. We provide evidences of 4-HPR-induced autophagy at a lower concentration (5 microM)...

avo theory was introduced around 20 years ago. in recent years, this technique was become to a major tool in hydrocarbon sources exploration. by the help of this method with the suitable understanding from underground layers and knowing how to use this technology, quantitative specifications of reservoir can be recognized. avo analysis is a seismic technique that by using of pre-stack data, est...

Abstract Amplitude Versus Offset (AVO) analysis has been successfully applied in the hydrocarbon industry for more than three decades. This effective tool of joint seismic and well-log data processing enables to predict analyze fluid saturated porous geological formations. AVO methodology is based on anomalous behavior pre-stack reflected amplitudes observed from bearing rocks. However, potenti...
