Abstract

Multicomponent (MC) seismic data are gaining importance as an exploration tool for difficult targets. Vector acquisition of seismic data in three orthogonal directions (3C) allows for the recording of both compressional (P) and shear (S) waves. These respond differently to fluid and solid combinations in the subsurface and the joint use of both wave modes provides many potential benefits. Applications relate to structural imaging (seeing through gas clouds, better fault definition, improved near-surface resolution), fracture characterization (density and orientation), fluid discrimination and estimation of lithology (sand/shale, dolomite/anhydrite). Furthermore, vector recordings allow for improved noise attenuation with respect to conventional P-wave records. <br>This paper provides an overview of multicomponent technology and focuses on the techniques and advances that are improving viability and includes theory and practical examples of how multicomponent technology is improving the ability of the industry to find and produce more oil and gas.<br>
