Required Geosteering Components: Technology • Logging while drilling • Specialized software for geosteering Staff • Geosteering Engineers Process • 24/7 • Interaction scheme • Reporting Some aspects. • When drilling horizontal wells, the magnitude of errors and uncertainties is comparable to the thickness of the target interval; • Geometric drilling is associated with a high risk of losing part or all of the wellbore in a non-reservoir; • Losses of the productive length of the horizontal section entail serious financial losses; • It is necessary to use LWD and real-time geosteering for optimal wellbore placement in the target interval. The advantages of geosteering from our company • The geosteering service is organized according to the standards of the leading companies in the industry, but not tied to the telemetry and NNB contractor; • Qualified personnel - geosteering engineers with over 7 years of experience; • Geosteering in real time (24/7); • Specialized software for geosteering. TRIASSIC Our goal is to create on the Russian oil and gas market a sustainable offer of high-tech consulting, providing oil and gas and service companies with consulting services from professionals from various fields, gathered from all over the world into a single team.
