... to reach a downhole sensor provides velocity information which can provide a significant reduction in depth uncertainty while drilling. The closer the seismic sensor is to the formation of interest then the more accurate the depth prediction of the formation top is. In addition, seismic reflections from...

... Abstract In marine oil and gas exploration of seismic data acquisition, both primary and multiple reflections are recorded at the streamers. In seismic data processing, primaries are usually used as signal to image the subsurface; multiples are regarded as noise to be removed (SRME) (Verschuur...

... information such as shear strength. Since the introduction of multi-component seismics in offshore investigations the last 10 years, it has been proved that P-to-S converted waves (also called C-waves) bring useful and complementary information to PP reflections, in terms of imaging, lithology and fluid...

Abstract Mass transport complexes (MTCs) in the Ursa region (northern Gulf of Mexico) are identified by their low seismic reflectivity, increased resistivity, increased bulk density, high shear strength, and decreased porosity. We integrate seismic, logging while drilling (LWD), and core data...

Such shear waves are generated by P to S conversion so they do not require special shear sources. The converted PS reflections provide additional information to what is in the PP reflections. The additional...
