The FASTrak Prism service adds a new level of measurement precision to the proven family of FASTrak fluid sampling-while-drilling solutions. Through its advanced sensors—including a VIS–NIR spectrometer—the FASTrak Prism service fully characterizes your reservoir fluids, in real-time. The service also provides real-time formation pressure and mobility data for enhanced efficiency, superior well placement, and improved wellsite safety.

And through its multi-channel optical density and fluorescence measurements, the service allows you to:

•Accurately quantify fluid type and fluid fractions in multi-phase flow
•Map compositional changes within a reservoir column
•Assess reservoir connectivity
•Monitor and maintain single-phase flow when sampling reservoirs close to saturation pressure
•Continual fluid measurements while drilling reduce risk and rig time, while accurately tracking any contamination and reservoir fluid properties prior to capturing a fluid sample. 

Real-time characterization rarely provides the full reservoir analysis you need for strategic decision making. The FASTrak Prism service collects fluid samples with the quality, volume, and reliability required for confident, accurate analysis.

The service collects up to 12 liters of single-phase reservoir fluid per run—more than other commercial logging-while-drilling (LWD) services can reliably deliver. This gives you the fluid volumes you need for more detailed analysis, without multiple sampling runs.

And to ensure sufficient quality, the FASTrak Prism service incorporates proven FASTrak sample collection methods. The sample tanks use a nitrogen pre-charge to keep your samples in single-phase state, which maintains sample pressure above both the asphaltene onset pressure and saturation pressure. The service’s SmartPad™ closed-loop sealing system provides an efficient seal, even in highly unconsolidated sand formations and irregular boreholes.
