Building on the success of the BAT™ and QBAT™ tools, Sperry Drilling services has taken velocity measurements to a new level with the XBAT™ azimuthal sonic and ultrasonic LWD service. The tool combines multipole transmitters and four azimuthal receiver arrays, along with a 4-pinger acoustic caliper.
The XBAT LWD service delivers accurate acoustic measurements in a wide range of formations via sensors and electronics that are much less sensitive to drilling noise and have a wider frequency response. The result is a greater signal-to-noise ratio that enables better measurements even in noisy drilling environments and poor hole conditions.
The XBAT LWD service helps you to drill safer, faster, and on target in challenging environments, mitigating risk through pore pressure prediction and hole shape information for wellbore stability monitoring, and optimizing the position of your wellbore with synthetic seismograms that tie back to surface seismic data.
The Halliburton product service line’s 24/7 support – both in-house and within the integrated real-time operation center (iROC) – ensured that every wellbore section, including the depleted reservoir interval, was drilled with minimal fluid losses and that the wellbore was at total depth (TD) before the oil-water contact (OWC).
In this well, drilled on a man-made island in the Beaufort Sea of Alaska,
the operator’s primary objective was to log cement behind casing.
Historically, well inclinations as high as 80 degrees in applications
in this area create cementing challenges including micro-annulus,
channeling, and fluid losses. In these high inclination wells, typical
logging tools with two receiver arrays 180 degrees apart were unable to
provide sufficient indication of the orientation of the azimuthal view of
the casing and thus, no confirmation of where problems occurred.
