DIFFRACTION IMAGING: A STRATTON FIELD, TX CASE STUDY
In recent years the Oil & Gas Industry has been searching for new technologies to increase 3D seismic resolution and fracture detection for shale unconventional reservoirs. Since most shale reservoirs are thin-layered and ...
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 ...
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 ...
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 ...
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 ...
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 ...
