Seismic Tomography for the Integrity Assessment of Earthen Dams and Levees.
… examines the use of a non-invasive geophysical seismic method to provide additional information where the usual visual inspection is insufficient and the comboring investigation is not an option. Even though seismic techniques provide valuable information of the subsurface strata, the …

Seismic Modeling and Imaging for Detection of Clandestine Tunnels
… Mexico. The reliability of a specific scientific method that can detect tunnel locations accurately has not been established yet. Among many proposed methods, seismic method is a promising technique for imaging those tunnels, despite its many potential drawbacks, such as low signal-to-noise ratio …

Elastic-Wave Imaging Using P-P, Sh-Sh, and Sv-P Events: Modeling and Data Processing
This thesis focuses on using seismic data that were generated by a vertical vibrator and recorded by a vertical geophone to build two different subsurface images: a conventional P-P section and a converted-wave SV-P section. Radiation patterns are calculated based on Miller and Pursey’s equations …

Integrated, Basin-To-Reservoir Scale, Geologic and Geophysical Studies of a Carbonate-Hosted, Hydrocarbon Reservoir of the La Vela Basin, Northwestern Venezuela
… with a basin-scale database of 1100 km2 of 3D seismic data and 52 wells from the Venezuelan national oil company (PDVSA) to assess carbonate reservoirs of the La Vela Basin (LVB). The LVB produced small quantities of oil and gas from carbonate reservoirs of early Miocene age since the 1970’s …

Defining Stress Changes Ahead of a Tunnel Face and Design of a Data Acquisition System
… tunnel construction continues to claim lives. A seismic method to aid in increasing safety during excavation is tomography. Seismic tomography is a non-invasive technique to map the stress changes induced by mining ahead of the active face. Seismic tomography maps the velocity distributions of …

Modeling Offset-Dependent Reflectivity for Time-Lapse Monitoring of Water-Flood Production in Thin-Layered Reservoirs
Seismic time-lapse monitoring of production is an important tool used to efficiently drain a hydrocarbon reservoir. Repeat seismic surveys may be used, because the seismic method is sensitive to the reservoir fluid. A prominent seismic attribute is the reflectivity (or amplitude) as a function of …

Actions on the conservation of the historical and archaeological heritage of Sicily using non-invasive geophysical exploration methods: Construction of a technical database website platform [Azioni per la conservazione del patrimonio storico e archeologico della Sicilia mediante l’utilizzo di metodi di esplorazione geofisica di tipo non invasivo: Costruzione di un database tecnico per la realizzazione in una piattaforma web]
Negli ultimi decenni, la tutela, la conservazione e la valorizzazione sostenibile del patrimonio storico, culturale, archeologico e ambientale hanno assunto un'importanza crescente nei campi scientifico e culturale, in particolare in Paesi come l’Italia e in modo specifico la Sicilia, …
