S-wave information, in conjunction with conventional P-wave, may quantitatively delineate reservoir condition and has progressively been playing important roll in recent oil/gas exploration and development. A reflection seismic method using PS converted waves (PS seismic) is considered one of the most promising approaches to collect S-wave data since it involves P-wave seismic sources instead of costly S-wave sources and the MEMS sensor has been dramatically reducing deployment cost. This expository paper summarizes PS seismic methods in three aspects; principal characteristics of S-wave, basic concepts of PS seismic, and its typical applications in the industry.
