Abstract

To explore the feasibility and to understand the behavior of shear waves generated at various interfaces due to mode conversion in weathered/sub-weathered zone, the idea of 3 component (3C) uphole was conceived in 2008. Geophysical party No. 06 of ONGC, successfully carried out experimental 3C Uphole survey in June 2008 by deploying three component digital sensors (SVSM) laid in specified star pattern geometry. This was probably the first ever attempt to acquired 3C uphole data in ONGC.
