English term or phrase: Reverse time migration
Reverse-Time Migration (RTM) is an ultra high-end prestack two-way wave-equation migration for accurate imaging in and below areas with both great structural and velocity complexities, such as sedimentary areas with steep salt inclusions. RTM has a proven track record for generating final images and is increasingly used for refining structural boundaries during velocity model building

Explanation:
Reverse time migration (RTM), being based on the two-way wave equation, can accurately account for wave propagation in both up and down directions. As a result, RTM can generate much improved subsurface images in areas where strong vertical velocity gradients generate turning waves or where rugose interfaces with strong velocity contrasts generate prism waves. In addition, because of its ability to image reflection events that cannot be imaged by other techniques, RTM can be used for refining a velocity model. ©2009 Society of Exploration Geophysicists
