Multiple Source Towed Streamer and Seabed “Hybrid” Seismic Acquisition in The Middle East

Summary The Arabian Basin contains some of the world’s largest fields and has a long and successful track record of exploration and production. The offshore waters have numerous legacy datasets, both towed streamer and ocean bottom seismic of varying vintages. To maximize existing field potential, E&P companies are embracing new innovations, leveraging new technology to improve sub-surface knowledge through advanced seismic acquisition and/or reprocessing techniques. For the last 50 years there has been oil and gas production offshore Dubai. Around and within the case study, outlined in this abstract, there are four active fields that contain seventy-five platforms. Until 2019, the area was covered by 2D seismic exploration lines and a number of focused 3D surveys acquired in the 1990s: OBC data was acquired over “Field One” and towed streamer over “Field Three”. Both datasets had been reprocessed, with the most recent performed approximately 10 years after acquisition. The inherent limitations in the legacy data had now been reached and this meant there was a requirement for new seismic over the area.
