"The Center for Lithospheric Studies is a research institute devoted to the study of the lithosphere through geophysical and geochemical means. The Center operates in close cooperation with the Department of Geosciences at The University of Texas at Dallas. The UT Dallas Geophysical Consortium is an industrial consortium of oil, service, and computer companies that was formed in 1987 for the support of research in exploration and reservoir geophysics at The Center for Lithospheric Studies (CLS) at The University of Texas at Dallas (UTD). 2011 is our 25th consecutive year of operation."

Combining Multidirectional Source Vector with Antitruncation-Artifact Fourier Transform to Calculate Angle Gathers from Reverse Time Migration in Two Steps
(Society of Exploration Geophysicists, 2017-08-11)Because receiver wavefields reconstructed from observed data are not as stable as synthetic source wavefields, the source-propagation vector and the reflector normal have often been used to calculate angle-domain common-image ... -
Estimation of Gas Hydrate and Free Gas Saturation, Concentration, and Distribution from Seismic Data
(Society of Exploration Geophysicists, 2018-08-24)Gas hydrates contain a major untapped source of energy and are of potential economic importance. The theoretical models to estimate gas hydrate saturation from seismic data predict significantly different acoustic/ elastic ... -
Up/Down and P/S Decompositions of Elastic Wavefields Using Complex Seismic Traces with Applications to Calculating Poynting Vectors and Angle-Domain Common-Image Gathers from Reverse Time Migrations
(Society of Exploration Geophysicists, 2018-06-01)Separations of up- and down-going as well as of P- and S-waves are often a part of processing of multicomponent recorded data and propagating wavefields. Most previous methods for separating up/down propagating wavefields ... -
Common-Reflection-Point Migration Velocity Analysis of 2D P-Wave Data From TTI Media
(Soc Exploration Geophysicists, 2014-05)We have developed a common-reflection-point (CRP)-based kinematic migration velocity analysis for 2D P-wave reflection data to estimate the four transversely isotropic (TI) parameters VPo, δ, and ε, and the tilt angle ϕ ... -
Comparison of Methods for Extracting ADCIGS from RTM
(Soc Exploration Geophysicists, 2014-04-01)Methods for extracting angle-domain common-image gathers (ADCIGs) during 2D reverse-time migration fall into three main categories; direction-vector-based methods, local-plane-wave decomposition methods, and local-shift ...
