Optimal Background Model Extraction and Improvement of RTM Illumination on Basis of Born Modeling
Seismic processing methods exist that view the actual velocity configuration of the subsurface as being composed of a reference model plus a perturbation of the reference velocity. Seismic migration (or imaging) requires ...
Vp-Vs Relations of Organic-rich shales
Organic-rich shales can serve as both source rocks and reservoir rocks. They are becoming increasingly important exploration and exploitation targets; however our knowledge of organic-rich shale properties is poor. Mudrock ...
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 ...
Estimation of The Source Mechanisms of Microseismic Events from a Barnett Shale play
The waveforms generated during hydraulic fracturing in unconventional oil and gas reservoirs contain information about the nature of the failures that gave rise to the observed wave fields. Inverting for the moment tensor ...
ENHANCEMENT OF THE GEOLOGICAL FEATURES OF THE SCOTIAN BASIN BY THE APPLICATION OF SPECTRAL INVERSION, OFFSHORE NOVA SCOTIA
Reflections from the top and bottom of beds thinner than λ/4 cannot be distinguished from one another due to the limit of seismic resolution. It would be advantageous for geoscientists to image thin beds below resolution, ...
IMAGING CRUSTAL STRUCTURE BENEATH TEXAS FROM RECEIVER FUNCTIONS
The shallow crust in Texas has been intensively investigated through seismic exploration for hydrocarbon resources. However, the deep crustal structure of Texas is not well understood. This thesis aims to illuminate crustal ...
