The multilayer service is said to deliver clearer boundary delineation compared to previous bed-boundary detection services.
It uses 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 feet radius.
According to Schlumberger, the PeriScope Edge helps drillers sustain a more accurate trajectory while inside the reservoir, which contributes to greater reservoir exposure that leads to optimal production.
Jesus Lamas, President, Well Construction of Schlumberger, said:
- Reducing geological uncertainty plays a critical role to improve drilling performance
- 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
Offshore China, an operator drilling 2 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.
