The OBEi1 Deep Marine is a state- of-the-art ocean- bottom electrical imager. A remotely operated underwater vehicle (ROV) carries the OBEi1 and is pulled behind a boat with a cable system at roughly one kilometer in depth. The cable—which typically spans approximately 1 kilometer behind the ROV—uses a Kevlar- strength member, water-block inner seal, and rugged marine jacket. The OBEi1 sensor has 56 AGI graphite electrodes (US patent 6,674,286) available in custom spacings.
USE CASES
The OBEi1 has been designed specifically for oceanic applications, including geohazard research, sediment research, fracture imaging, and mineral, oil and gas exploration. Here are a couple of additional applications where the OBEi1 excels:
- Subsurface Geotechnical Site Investigation For Oil Platforms
- Gas Hydrate Exploration
