MWD / LWD Services
NaviTrak MWD service delivers reliable, real-time downhole information including hole inclination, azimuth, and toolface orientation. These measurements, coupled with drilling dynamics and natural gamma-ray readings, reduce risk and enable precise wellbore positioning.
The NaviTrak platform is based on a sensor probe design which uses standard drill collars coupled with our proven telemetry modules. Power is generated down hole by a turbine-alternator assembly, but there is also the option to deploy with batteries in place of the turbine and alternator.
The NaviTrak service allows the accurate placement of the well and the determination of lithology in multiple drilling applications. The robust mud-pulse telemetry system transmits downhole information quickly to the surface, and trained personnel ensure service quality, allowing continuously drill ahead.
The LWD systems offer superior formation evaluation data to maximize reservoir value while drilling. LWD sensors deliver wireline quality petrophysical data and address directional drilling, formation evaluation, and geosteering applications. The tools will help in gathering reservoir information, enhance drilling performance, and optimize well placement.
Gamma services are probe-based or collar-mounted with our MWD service. Gamma-ray sensors detect lithology changes.
Resistivity services are offered through the OnTrak™ system, delivering comprehensive evaluation of formation and near-bore environments. Other LWD systems that we offer in conjunction with our partners, Baker Hughes Inc., are as described below.
LithoTrak system offers accurate nuclear measurements and formation-density images. Real-time azimuthally sectored bulk density and neutron-porosity measurements are designed for integration within rotary steerable drilling systems.
Magnetic resonance services offer a lithology-independent porosity measurement while drilling through our MagTrak™ system, quantifying fluids occupying pore space into fractions that contribute to production and fractions that do not. MagTrak measurements aren’t affected by formation, borehole, or near-borehole environment.
Formation pressures services offer real-time measurements of formation pressure while drilling. The TesTrak system determines reservoir fluids mobility, optimizing the acquisition period and minimizing the total time required to accurately measure formation pressure. This minimizes NPT.,hr>
Imaging services offer high-resolution images for geological and structural classification, sedimentary analysis, and steering. The AziTrak system, LithoTrak system, OnTrak system, and StarTrak system improve imaging for reduced drilling risk.
Acoustic service is offered via SoundTrak technology, which integrates advanced downhole acoustic technology into our existing modular tool design and runs with many formation evaluation service levels.
The Reservoir Navigation Services use real-time LWD formation evaluation sensors with directional data and formation models to properly target your drilling assembly. This ensures optimal entry to maintain the wellbore in the zone of maximum interest, predicting and avoiding reservoir exit. Azimuthal imaging also is available.
