To see what is underneath the surface of the earth, we can drill a borehole, or perform what is called “seismic imaging”. Whereas boreholes give very localized information, seismic images can result in tens of thousands square kilometres being digitally imaged down to several kilometres, and analysed for rock strata, structures and fluids such as oil and gas. Such experiments use multi-sensor arrays to listen to the energy reflected from the earth’s interior much like a bat uses ultrasonic echo-location or a CT scanner uses X-rays to image inside our bodies. The physics of wave-propagation is well understood, in theory, and yet seismic imaging is a hard problem, computationally intensive, and often the solution is under-determined, despite TBytes of field data available for analysis. Could deep learning be a game changer?
