High-speed telemetry-while-drilling service
Simultaneously transmit multiple datasets with high-speed measurements while drilling.
The StethoScope service provides formation pressure-while-drilling (FPWD) measurements that are used to predict pore pressure trends throughout the wellbore. Profiles generated by the service’s real-time calibration points combine with other LWD logs to model dynamic reservoir pressure, which is crucial to optimizing recovery. These pore pressure models also foster a better understanding of production systems.
The use of real-time LWD measurements—specifically resistivity and sonic measurements—to predict pore pressure trends provides data assurance in any hole deviation or orientation. Once the pore pressure is known, mud weight can be optimized, allowing drilling to continue at optimal penetration rates without kicks and drilling delays. Accurate formation pressure evaluation also eliminates costs associated with premature casing runs and incorrect casing placement.
In virgin reservoirs, pressure profiles can be combined with other LWD logs to develop a static model of the reservoir. Pressure and mobility data help target the most productive zones and determine the optimal drain length for horizontal wells. In developed reservoirs, pressure profiles also help to evaluate fluid movement, and rapid pressure analysis aids in effective geosteering between compartments in faulted formations.
Real-time StethoScope service measurements, delivered to surface by on-demand frame technology, facilitate geosteering and geostopping decisions based on the pressure regimes encountered. Quick decisions can avoid time spent drilling pressure-related formations and preserve virgin pressure zones scheduled for sidetrack development or completion.
