ABSTRACT:
A broadline seismic survey is carried out by positioning a plurality of areal arrays of seismic detectors along each of a plurality of broadline receiver lines along the surface of the earth. Array centers along an inline direction of each receiver line are staggered by one-half of an array interval from array centers along the inline direction of adjacent receiver lines. Each detector array on a given receiver line is elongated in a cross-line direction to such receiver line to effect an areal array coverage between broadline centers of the adjacent receiver lines being on opposite sides of the given receiver line. The seismic detectors in each array are connected in common to a recording means.
