Geophysical Responses of Organic-rich Shale and the Effect of Mineralogy
Total organic carbon (TOC) is one of the most important parameters for indicating the resource potential of unconventional shale reservoirs. Because of the low density and velocity of organic matter, some seismic attributes ...
Multicomponent seismic imaging of sand reservoirs: Middle Magdalena Valley, Colombia.
Many current resource exploration targets are more difficult to image and assess than in the past; thus, more complete and sophisticated techniques, such as the multicomponent (3C) seismic method, are needed. The scope of ...
Building 3-D Crustal Model with Radial Anisotropy in Iceland from Ambient Seismic Noise Tomography
Iceland is a place of great geophysical interest due to its location at a hotspot and on the Mid-North Atlantic Ridge. Despite numerous studies conducted on Iceland, there remain fundamental disagreements on such questions ...
MICROSEISMIC MONITORING: PHYSICAL MODELING AND SOURCE CHARACTERIZATION
This research investigates some fundamental aspects of microseismic monitoring: location and source mechanism. We developed a ray-tracing and diffraction-stack procedure to determine source locations. The location algorithm ...
S-wave velocity estimation using converted-wave VSP data
One of the key benefits of zero-offset vertical seismic profile (VSP) is to provide accurate velocity information in the vicinity of boreholes. For 3-component VSP, we usually pick the first break times of direct downgoing ...
Elastodynamic Green's tensor in anisotropic medium
This thesis is dedicated to study the elastodynamic Green’s tensor in anisotropic medium in order to understand the influence of anisotropy on the point source radiation. In the first part of this thesis, a new form of ...
