Utilizing advanced seismic techniques for delineating hydrocarbon accumulations in HST (High Stand System Tract) turbidite channel of Kafr El-Sheikh (KS) formation (Pliocene Age) located the western part South Batra field (SBF), Nile Delta – Egypt is investigated. 3D data and four well logs helped studying properties channel. Three wells encountered central showed thicker reservoir thickness th...

The variation in seismic P to P reflection amplitude with offset (AVO) caused by a system of fractures embedded in an isotropic background is investigated. Additionally. a sensitivity analysis of AVO parameters with respect to the fracture system parameters is made. The fracture system is assumed to be aligned vertically or horizontally and can be gas filled or fluid filled. Elastic constants a...

The AVO and AVAz contain valuable information about the elastic properties of a subsurface media. However, the conventional approaches are based on plane-wave theory, which cannot explain observations near the acoustic critical reflection and far offset null reflection at Rayleigh angle. In this contribution, we show our algorithm to understand the acoustic reflectivity of liquid-solid boundary...

Oil and gas production from tight, fractured reservoirs (sandstone, carbonates and shale) has increased significantly over the last decade. These hard rock targets are often characterized by vertically aligned fractures (i.e. HTI) embedded in a layered sequence (i.e. VTI). In this geologic setting, seismic velocities and η can vary with azimuth and depth. This is orthorhombic anisotropy and can...

Regarding absorption spectrum, high corresponds to low light transmittance and relatively loud noise, whereas information content, which interferes with the modeling of spectral analysis. Appropriate absorbance level is necessary improve content reduces noise level. In this study, based on selection upper lower bounds absorbance, value optimization partial least squares (AVO-PLS) method was pro...
