A unified approach to complex seismic imaging problems
Two current challenges in seismic imaging are to obtain more detailed images of complex structures from reflection data and to constrain the regional structure of the Earth using wide-angle data. These are complex problems ...
Waveform tomography and its application at a ground water contamination site
This thesis develops and applies seismic waveform tomography to solve the unique problem of imaging complicated shallow sub-structures with high resolution. Shallow sub-structures are commonly characterized by seismic ...
Converted modes in subsalt seismic exploration
Salt has unusual properties which complicate seismic exploration. A Model study examines some problems encountered in subsalt amplitude analysis and demonstrates that traditional techniques for detecting hydrocarbons and ...
Application of seismic tools and techniques to ground-penetrating radar (GPR) studies
Seismic techniques and tools have not routinely been transferred to ground-penetrating radar (GPR) studies due to computational, financial, and logistical limitations. A simple processing package was developed to aid in ...
On a transmission inverse problem
In crosswell seismic experiments, seismic sources are fired in one well, and the wave-fields generated are measured in another well. The goal of the crosswell seismology is to find physical parameters, especially the ...
The growth of fractures in the Earth
Fracture growth under compressive loading is studied using the maximum strain energy release rate criterion by means of both the finite element and the boundary element methods. Although this approach is computationally ...
