Abstract

This paper is focused with a collaboration of smart alert system and prediction of geological boundaries which help enhancing the decision making while drilling in target zone in geosteering operations. Monitoring multiple wells in a high operational condition has become a big challenge for geosteering operations. An integrated smart system that produces an alert when the well deviates from target zone while drilling was a solution which improve operations efficiency. Real time data is processed by the algorithms and outputs the predicted recommendation if adjustment in inclination is required to keep the best contact with the reservoir. The real-time data is processed through the integrated alert system by a set of algorithms to recognize the conditions when the drill-bit goes out of the reservoir based on Logging While Drilling (LWD) characteristics. This improvement equips a complete workflow of geosteering operations where it involves comprehensive understanding of real-time data infrastructure, log formats and data processing, and effective communication between geologist and petrophysicist about the reservoir criteria. We are convinced this solution increases the efficiency to take the advantage of the geosteering operations and inspire others to pursue the benefit of real time data and its analytical capability.
