Calculation of a Synthetic Gather using the Aki-Richards Approximation to the Zoeppritz Equations
<p>A synthetic seismic gather showing amplitude versus offset can be analyzed by the interpretive geophysicist to predict rock properties useful in oil exploration. Reflection coefficients derived from measured well log data are convolved with a Ricker wavelet to create a synthetic seismic trace. …

Investigation into the applicability of AVO techniques to coal mine exploration
AVO (for Amplitude Versus Offset) is a seismic technology known in the oil industry for its ability to differentiate gas sands (over oil producing reservoirs) from wet sands (over non-producing reservoirs) in the Gulf of Mexico. Its applicability to a broad range of exploration fields has led to …

Seismic scattering attributes to estimate reservoir fracture density : a numerical modeling study
… of velocity is analyzed using integrated amplitude and spectral attributes that focus on time windows around the base reservoir reflection and the scattered wave coda after the base reservoir reflection. Results from a common shot gather show that when the fracture zones are spaced greater …

USING AVO ANALYSIS TO DETERMINE THE GAS RESERVOIRS IN THE SOUTH THRACE BASIN, NORTHWEST TURKEY
… to calculate Poisson’s Ratio and preserving amplitude are very significant in order to obtain a successful AVO result. These features can help determining reservoir locations and increasing gas productivity. The main objective of this thesis is to understand rock properties at the possible …

Processing Case Study with AVO and Pore Pressure Analyses: Eugene Island, Gulf of Mexico
… attributes, well-log calibration, and AVO (Amplitude Versus Offset) and pore pressure analyses. While the supporting theory for each method has been well established, an integration of the methods to a real exploration project can be confusing for the uninitiated. Given a seismic dataset and …

Pore fluid pressure detection within the plate boundary fault interface of the Costa Rica convergent margin using AVO attributes
I conducted an amplitude vs. offset (AVO) analysis on newly acquired 3D seismic reflection data to detect elevated pore fluid content and pore fluid pressure along the Costa Rica convergent margin to address dewatering processes of subduction zone sediments. These data provide the highest quality …

Deep learning methods for shear log predictions in the Volve field Norwegian North Sea
… various seismic analysis applications, such as Amplitude Versus Offset (AVO) inversion and multicomponent seismic interpretation. Furthermore, shear logs or their inverse shear velocity logs are an essential component for rock physics analysis in order to constrain seismic inversion results for …

Estimation of seismic parameters from multifold reflection seismic data by generalized linear inversion of Zoeppritz equations
… horizontal boundary from P-wave reflection amplitude-versus-offset (AVO) data recorded at the surface. The method has for its basis the inversion of the plane wave Zoeppritz. equations by generalized linear inversion (GLI) and bootstrapping. The Zoeppritz equations are converted into the …

Seismic characterization of fractured reservoirs (part I) ; Crustal deformation in the Tibetan Plateau (part II)
… of data is more beneficial than using reflection amplitude data alone. Quantitative interpretation can be difficult when using the P-wave seismic signatures alone because of the variables discussed above. Considering heterogeneity of fracture density due to spatial variations, statistical …
