A method of three-dimensional seismic acquisition comprising providing a plurality of substantially parallel source/receiver lines, each said source/receiver line comprising a linear array of seismic energy receivers at substantially equally spaced station intervals and a linear array of seismic energy sources located at each second station, adjacent source/receiver lines being spaced apart by two station intervals; initiating a seismic disturbance from one of said sources and receiving seismic energy at receivers disposed symmetrically about said source. Because of single direction coarse bin dimension, there is a requirement to reconstruct a uniform bin size through cooperative wavefield reconstruction in processing. The stacked common bin gathered volume of the near patch geometry of the present invention is so robust with spatially consistent, broadband signal frequencies, that accurate dealiased interpolation can be applied, e.g., by using standard F-X prediction.

L'invention est une méthode d'acquisition de données sismiques tridimensionnelles qui consiste à fournir une pluralité de lignes source-récepteur essentiellement parallèles, chacune de ces lignes comportant un réseau linéaire de récepteurs d'énergie sismique installés dans des stations essentiellement à égale distance l'une de l'autre et un réseau linéaire de sources d'énergie sismique installées à chaque station alternée, les lignes source-récepteur adjacentes étant espacées l'une de l'autre par deux intervalles de station; la méthode consiste également à amorcer une perturbation sismique au moyen d'une des sources et à recevoir l'énergie sismique aux récepteurs installés symétriquement par rapport à cette source. Cette méthode permet d'utiliser une interpolation à dépliement de précision.
