PS imaging of ocean-bottom data

Back to Technical Content
We describe opportunities and challenges for imaging seismic data acquired using conventional marine sources and receivers located on the seafloor. Opportunities include the promise of greater imaging resolution than sea-surface acquisition and processing can offer, especially using P-wave to S-wave converted reflection energy (PS imaging). Challenges include effects of current seafloor receiver spacing, which can be large enough to negate the promised resolution gains. We use a synthetic dataset to illustrate possible imaging improvements that can result from seafloor acquisition, as well as image degradation that can result when seafloor receivers are separated by typical current distances.
