Reduce formation pressure uncertainty
StethoScope formation pressure-while-drilling (FPWD) service minimizes risk and reduces cost with real-time calibration points for pore pressure models. This service enables mud-weight optimization so that drilling can continue confidently at ideal penetration rates.
FPWD measurements also improve casing point selection by offering a better understanding of the formation pressure around the planned casing point, reducing risk.
Real-time measurements for geosteering and geostopping
Real-time formation pressure measurements (delivered to surface by On Demand Frame technology) eliminate time wasted drilling pressure-depleted formations and preserve virgin pressure zones scheduled for sidetrack development or completion. Pressure and mobility data help in targeting the most productive zones and determining the optimal drain length for horizontal wells. In faulted formations, rapid pressure analysis enhances effective geosteering between compartments.
Accurate data for improved formation evaluation
In developed reservoirs, pressure profiles help to understand fluid movement. In virgin reservoirs, pressure profiles can be combined with other LWD logs to develop a static reservoir model. For pretests, TOP time-optimized technology supplies reliable data.
Using these pressure profiles to model the dynamic reservoir pressure optimizes recovery. The model enables an increased understanding of a field's production systems, leading to better completions.
