Schlumberger’s PeriScope to optimise reservoir exposure

oil well 19 AUgSchlumberger has announced the launch of the PeriScope Edge multilayer mapping-while-drilling service that expands the depth detection range and improves resolution compared to existing services, while utilising cloud and digital solutions to offer reservoir insights

According to Schlumberger, this reduces uncertainty and ensures optimal reservoir exposure while drilling, thus enhancing well construction efficiency.

Jesus Lamas, president, well construction, Schlumberger, said, “The PeriScope Edge service introduces new measurements and an industry leading inversion process, enabled by hardware and digital innovations, to deliver accurate geosteering in reservoirs where multiple thin layers could not previously be mapped. This, combined with cloud computing and secure connectivity, creates a unique geosteering workflow that links stakeholders for instant decision making, which results in optimal reservoir exposure improving net-to-gross ratios, and ultimately greater overall drilling performance that unlocks full reservoir potential.”

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,” stated Schlumberger.
