According to R. Rasmus Sunde, president of ABB Offshore Systems, "This alliance combines ABB's leading expertise in designing, testing, manufacturing and commissioning subsea infrastructure with Input/Output's superior VectorSeis(R) seismic imaging technology."
Sunde continues, "During conventional 4D surveys, marine streamers are towed behind an acquisition vessel. 4D streamer acquisition has become well proven in provinces such as the North Sea. In contrast, permanently deployed ocean-bottom cable (OBC) networks place seismic sensors directly on the seabed. This method improves frequency content and repeatability of 4D surveys compared to streamer acquisition, and enables shear wave collection for enhanced reservoir characterization. Our mandate will be clearly focused on reducing the historically high costs of OBC acquisition while improving data quality and reliability."
Input/Output's unique sensor technology is based on a proprietary micro-electro-mechanical systems (MEMS) sensor that, along with patented I/O cable decoupling technology, yields improved reservoir imaging. Integration of I/O's new sensors with ABB's subsea infrastructure will optimize the equipment required to support the solution.
Larry Denver, Reservoir Operations vice president for Input/Output, explains, "Permanent OBC systems measure reservoir responses to production and provide both active and passive seismic data. Timely access to this information by operators can substantially improve reservoir management."
Denver emphasises, "Based on our successful prototype system deployment last fall in the North Sea, we are moving quickly to materially improve OBC capabilities. This alliance forms the cornerstone for building these capabilities and attracting other best-in-class providers to participate in an overall solution."
