The AziTrak™ deep azimuthal resistivity measurement service from Baker Hughes detects reservoir boundaries, offering accurate formation evaluation to reduce wellbore position uncertainty. When combined with our Reservoir Navigation Services, the AziTrak tool enables optimal wellbore placement for increased production in horizontal and multilateral wells. This approach reduces nonproductive time (NPT) by avoiding unnecessary sidetracks.

This formation evaluation tool is a fully integrated MWD/LWD (measurement-while-drilling/logging-while-drilling) suite, offering real-time deep azimuthal resistivity, directional, azimuthal gamma-ray, multiple propagation resistivity, downhole pressure, and vibration measurements in a single sub. All the sensors are as close as possible to the bit for early detection of undesirable reservoir sections.

By geosteering away from unproductive lateral sections — whether oil-water contact (OWC) or avoiding an undesired reservoir exit — you’ll ensure optimal placement and maximized reservoir performance.

Real-time distance-to-bed boundary and apparent-dip calculations with deep azimuthal resistivity data and gamma-ray images are available for informed, proactive decisions while drilling horizontal wells.  

By addressing the critical challenges when there’s a high level of uncertainty in subseismic features, optimal wellbore placement is essential for maximizing reservoir exposure.


Collaboration achieves nearly 42,000 ft of reservoir section in two dual lateral wells

Working with an operator offshore Norway, one of our reservoir navigation services’ teams applied the AziTrak tool to geosteer 8.2 ft (2.5 m) above the OWC required for screen completion.

The AziTrak tool reduced the uncertainty of the OWC distance. We measured the OWC continuously throughout the 41,670-ft (12,700-m) horizontal section, enabling an OWC surface map.

With this information, we accurately tracked the OWC while drilling, achieving more than 90% pay zone in two dual laterals with two branches each.
