Methods and apparatus are described for the seismic exploration of strata adjacent to a borehole, wherein an arrangement of geophones is lowered into the borehole and clamped to the wall. The geophones are clamped at essentially equal angular distances along the circumference of the borehole. A plurality of such arrangements can be positioned along the longitudinal axis of the borehole. By combining the outputs of the geophones noise signals generated by symmetric guided waves are attenuated. The arrangement can be used for cross-well seismic acquisition and in combination with seismic sources and/or attenuator so as to form an single-unit exploration tool for borehole seismics.

Méthodes et appareil de prospection sismique de strates dans un trou de forage. Un montage de géophones est descendu dans le trou et fixé à la paroi. Les géophones sont fixés suivant des écarts angulaires essentiellement égaux sur la circonférence du trou. Un certain nombre de ces montages peuvent être positionnés sur l'axe longitudinal du trou. La combinaison des sorties des géophones atténue les bruits produits par les ondes guidées symétriques. Le montage peut être utilisé pour l'acquisition de données sismiques de puits et en combinaison avec des sources sismiques et (ou) un atténuateur afin de former un outil de prospection unique pour la sismique de puits.
