HOUSTON – Schlumberger announced the launch of the PeriScope Edge multi-layer drilling mapping service. The new service expands the depth sensing range and improves resolution compared to existing services, while using digital and cloud solutions to provide reservoir information. This reduces uncertainty and ensures optimal reservoir exposure during drilling, thus improving well construction efficiency.
“Reducing geologic uncertainty plays a critical role in improving drilling performance,” said Jesus Lamas, president of Well Construction at Schlumberger. “The PeriScope Edge service introduces new measurements and an industry-leading investment process, enabled by hardware and digital innovations, to provide 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, resulting in optimal reservoir exposure that improves net ratios. to gross and ultimately higher overall drilling performance that unlocks the full potential of the reservoir. “
New measurements extend detection depth and improve resolution compared to previous bed boundary detection services, enabling the PeriScope Edge service to provide clearer boundary delineation, even for multiple layers 3 feet 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-foot radius. Leveraging these capabilities, the PeriScope Edge service helps drillers maintain a more precise trajectory within the reservoir, contributing to greater reservoir exposure leading 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 the PeriScope Edge service to increase understanding of the reservoir in sandstone, allowing for more effective targeting within the horizontal section of the wells. The technology helped the operator double the detection range compared to existing services, providing greater reservoir visibility that enabled effective geosteering decisions in real time. As a result, the operator achieved a net / gross ratio of 100%, which allowed for higher productivity.
