AlphaSight

AlphaSight™ 3D reservoir mapping and look-ahead service enables operators to navigate complex reservoirs across all resistivity environments, including low-resistivity, low-contrast, or high-resistivity, low-contrast cases. AlphaSight service, which integrates novel EM architecture into the latest SLB RSS technologies for class-leading bit-to-sensor offset, provides subsurface mapping while drilling using physics-based EM measurements. The measurement system uses a true triaxial collocated transmitter and receiver antenna arrangement, which differs from traditional LWD designs that often rely on noncollocated or tilted antennas. Operating at ultralow EM frequencies with a frequency spectrum that is both the densest and widest in industry, this innovative service delivers deeper signal penetration and higher resolution even in challenging formations. After decades of innovation in deep and ultradeep azimuthal resistivity geosteering and reservoir mapping technologies, SLB developed AlphaSight service with a novel multidepth azimuthal resistivity (MDAR) technology platform that significantly increases not only depth of detection but also vertical resolution around the wellbore and ahead of the bit while drilling. With AlphaSight service, you can see deeper, see clearer, and see sooner.
