Schlumberger Launches PeriScope Edge Multilayer Mapping Service

Schlumberger announced the launch of the PeriScope Edge multilayer mapping-while-drilling service. The new service expands the depth detection range and improves resolution compared to existing services, while utilizing cloud and digital solutions to offer reservoir insights. This reduces uncertainty and ensures optimal reservoir exposure while drilling, thus enhancing well construction efficiency.

New measurements expand the depth of detection and improve the resolution compared with previous bed-boundary detection services, enabling the PeriScope Edge service to deliver clearer boundary delineation—even for multiple layers of 3 ft or less. The multilayer service uses new deep-resistivity technology and a transverse antenna for multidirectional measurements to reveal up to eight bed-boundary layers, providing definition and certainty beyond a 25 ft radius. Leveraging these capabilities, PeriScope Edge service helps drillers sustain a more accurate trajectory while inside the reservoir, which contributes to greater reservoir exposure that leads to optimal production.

The PeriScope Edge service has a proven track record in various formations globally, including South America, the Middle East, and Asia. Offshore China, an operator drilling two wells used PeriScope Edge service to increase reservoir understanding in sandstone, enabling more effective steering within the horizontal section of the wells. The technology helped the operator to double detection range compared to existing services, providing greater reservoir visibility that enabled effective real-time geosteering decisions. As a result, the operator achieved 100% net-to-gross ratio, enabling greater productivity.
