Relative performance of moveout-based multiple-suppression methods for amplitude variation with offset (AVO) analysis and common midpoint (CMP) stacking

We apply three moveout-based methods for multiple suppression to simple synthetic common midpoint (CMP) gathers and compare their performance in terms of level of multiple rejection and, more importantly, in terms of (1) suitability of processed output for use in analysis of amplitude variations with offset (AVO), (2) primary-to-multiple amplitude (p/m) ratio of the data after CMP stacking, and...

Short Note Reverse time migration in midpoint-offset coordinates

Reverse-time migration (Baysal et al., 1984) has some potential advantages with respect to downward-continuation migration. It can migrate overturned and prismatic reflections even in the presence of strong lateral velocity variations (Biondi, 2002). It also models the amplitude of the transmitted wavefield more accurately than downward-continuation in the presence of sharp interfaces. However,...

Imaging blended vertical seismic profiling data using full-wavefield migration in the common-receiver domain

For vertical-seismic-profiling (VSP) measurements, the use of blended acquisition, with time-overlapping shot records, can greatly reduce the downtime and, thereby, provide large cost savings. For directly imaging blended VSP measurements, we have used full-wavefield migration (FWM). FWM is an inversion-based imaging scheme that enables us to use any kind of complex source wavefield to estimate...

Offset plane waves vs. common-azimuth migration for sub-salt imaging

Offset plane wave migration and common-azimuth migration are among the most promising wave-equation migration methods for efficiently imaging 3-D marine data sets. Offset plane wave migration has some computational advantages over common-azimuth migration, but common-azimuth is more accurate. Sub-salt images produced by commonazimuth migration are better focused than the corresponding images pr...

Right ventricular tachycardia: common presentation versus common disease.

A 46-year-old man presented to the emergency department with palpitation and chest pain with hemodynamically stable wide complex tachycardia of left bundle-branch block morphology (Figure 1). Electric cardioversion restored sinus rhythm after a trial of intravenous amiodarone (Figure 2A). Echocardiography demonstrated a normal left ventricle (LV); however, the right ventricle (RV) was dilated w...
