Scientific Drilling’s Smart Motor & BitSub tool is a short-integrated sensor package. For instance, the package provides at-bit real-time continuous inclination, azimuthal gamma ray, and drilling dynamics measurements. The sensors are in an instrumented Smart Motor or a separate BitSub collar. Therefore, offering a high-precision azimuthal gamma ray less than 2 feet from the bit enables proactive geosteering decisions.

The at-bit continuous inclination gives immediate feedback on wellbore directional trends and motor output. Above all, allowing closer proximity to well plan trajectory.

Utilizing the Wi-Sci™ EM short hop for real-time data transmission, a wide selection of mud motor power sections can be used.  This EM short hop technology works in water- and oil-based mud systems. Furthermore, it is compatible with Scientific Drilling’s MP-MWD, EM-MWD, and LWD systems.

Scientific Drilling’s newest azimuthal gamma-ray tool employs an improved design for higher-quality gamma-ray imaging applications. This probe-based sensor is integrated with the HALO RSS or can be placed just above the mud motor in a conventional assembly.

As geosteering target windows thin, the gamma-ray variability can also decrease. Therefore, leading to uncertainty about whether the wellbore is cutting up or down stratigraphically. For example, employing a larger scintillation crystal and improved azimuthal shielding. The HAG sensor provides better-resolution imaging measurements to aid critical real-time well placement decisions.

An azimuthal gamma ray solution that provides measurements 20-25 ft (6-8m) closer to the bit than the MWD. It is an excellent tool for Geosteering – helping to keep the bit within the “sweet spot” of the reservoir.

On the Bottom Hole Assembly (BHA), Azi-Gain is placed just above the motor. Above all, giving the directional driller enough time to react to formation changes quickly. This technology can be run with any of Scientific Drilling’s MWD and LWD systems in all configurations.
