摘要
This application relates to methods and apparatus for seismic surveying using optical fibre distributed acoustic sensing (DAS). The method involves using a fibre optic distributed acoustic sensor to detect seismic signals. The fibre optic distributed acoustic sensor comprises an interrogator (106) arranged to interrogate at least one optical fibre (104) buried in the ground (204) in the area of interest. The method involves stimulating the ground using a seismic source (201 ) and detecting the seismic signals, for example reflected from various rock strata (202, 203).
