Onshore seismic surveys in the Middle East and North Africa benefit from integrated acquisition, data conditioning, and imaging flows designed to handle a wide range of challenging settings. We present the results of such an integrated survey west of the Oman mountains in Sharjah, UAE. The area is characterized by a highly heterogeneous near-surface geology with cultural obstructions, coupled with complex thrust-belt geology with steep dips, allocthonous events, and juxtaposed slow- and fast-velocity formations.
Point-source point-receiver broadband data and wide azimuths and offsets are needed for acquisition in conjunction with a data conditioning and advanced prestack depth migration (PSDM) workflow that takes advantage of these characteristics to build a velocity model that honors the complexity of the geology and wavefield propagation.
