Abstract: A method of conducting a seismic survey comprising using at least one seismic source operable to emit an acoustic signal comprises: - providing a first receiver line extending in a first direction across a region of the ground to be surveyed; - locating at least one seismic receiver at a point on the first receiver line, the seismic i receiver(s) being adapted to record reflected acoustic signals emitted by the seismic source(s); - providing a first pre-determined shot line having a plurality of shot points along its length, extending in a second direction and along which the seismic source(s) is movable; - operating the or one of the seismic source(s) to emit an acoustic signal at a first shot point on the pre-determined shot line, the reflection of the acoustic signal being recorded by the or one of the seismic receiver(s); and - operating the or one of the seismic source(s) to emit another acoustic signal at a second shot point on the pre-determined shot line, the reflection of the another acoustic signal being recorded by the or one of the seismic receiver(s); characterised in that at least one of the first receiver line and the first pre-determined shot line passes through or at least partially along a generally horizontal borehole extending through the region of the ground to be surveyed and the first pre-determined shot line transects the first receiver line.
