We introduce an integrated wave-equation technique for migration velocity analysis (MVA) that consists of three steps: (1) forming the extended data, (2) approximating the correct transmitted wavefield, and (3) using wavefield tomography to update th

Migration velocity analysis (MVA) is commonly performed in the image domain in conjunction with ray-based tomography to update the velocity model. This approach can be challenging in the presence of large velocity errors as it may require many MVA it

North America's great success in unlocking unconventional reservoirs has inspired many oil companies in the Middle East to focus on and develop their large unconventional endowment. To engage with the oil and gas industry in the region, SEG Middle Ea

Downward-continuation migration algorithms are powerful tools for imaging complicated subsurface structures. However, they usually assume that extrapolation proceeds from a flat surface, whereas most land surveys are acquired over irregular surfaces.

We present a new approach to the design and implementation of explicit wavefield extrapolation for seismic depth migration in the space-frequency domain. Instability of the wavefield extrapolation operator is addressed by splitting the operator into

Downward-continuation methods are very sensitive to velocity models (Berkhout, 1982; Yilmaz and Chambers, 1984; Claerbout, 1985; Al-Yahya, 1989; Deregowski, 1990; Liu and Bleistein, 1994; Varela et al., 1998). Using inaccurate velocity models in thes

Downward-continuation migration algorithms are a powerful tool for imaging complicated subsurface structures. The phase-shift plus interpolation (PSPI) algorithm is a downward-continuation algorithm that is still widely used in the industry due to it

Surface waves can have complicated wave paths when propagating through a complex near surface. Removing this dispersive energy is an important step to focus the subsurface seismic image. Model-based downward continuation techniques offer one solution
