Abstract
BP has acquired co-located 3D simultaneous source and conventional OBC surveys in both the North Sea and Trinidad to compare simultaneous source acquisition with conventional acquisition. A standard independent simultaneous source (ISS®) shooting method was used in Trinidad, while a combination of ISS and self-simultaneous shooting (SSS) was used in the North Sea. Two source boats were used with both simultaneous source surveys. Continuous recording was used to reduce the volume of data and simplify the acquisition. It was found that the quality of the processed images and gathers from both simultaneous source surveys were very similar to the quality of conventional surveys, but the acquisition was significantly more efficient.
