OVERVIEW | bakerhughes.com STAR-HD Imaging Service Get high-resolution formation resistivity imaging in conductive mud systems Applications nnDetermining dip and strike nnIdentifying and describing faults and fractures nnInterpreting sedimentary and stratigraphic properties nnStructural mapping nnObtaining well-to-well correlations nnUnconformity mapping nnUp-scaling to seismic and verifying a seismically derived structural model Features and benefits nnWide range of images with high signal-to-noise ratio Pictured are high-resolution resistivity images illustrating laminated and deformed bedding, and various fracture dip magnitudes and orientations. The Baker Hughes STAR-HD™ imaging service provides high-resolution formation resistivity imaging in conductive mud systems—even in wells drilled with salt-saturated muds. The wide range of the sensor arrays results in enhanced geological and petrophysical reservoir evaluation. The six-arm, independently articulated carrier and powered stand-off ensure optimal sensor-to-formation contact, even in highly deviated boreholes. On each of the six articulated arms are pads with 24 sensors, resulting in a total of 144 micro-resistivity measurements and a vertical and azimuthal resolution of 0.2 in. (5 mm). The resulting high-resolution borehole images help identify various geological features such as planar (bedding, fractures, faults), stratigraphic (cross-bedding, ichnofabrics), and borehole wall (breakout and drillinginduced fracturing). Whether deployed alone or in combination with the Baker Hughes CBIL™ or UltrasonicXplorer™ imaging services, the STAR-HD service helps you identify features for analysis of structural dip, fracture systems, depositional environments, borehole stability, and net pay in thinly bedded sequences. The STAR-HD and UltrasonicXplorer services allow the simultaneous acquisition of image data sets and are fully combinable with other Baker Hughes logging tools. –– Acquires data in conductive muds, resistivity formations, and environments with a high Rxo:Rm ratio –– Enables detailed evaluation of geological and petrophysical formation features nnCombinable with the UltrasonicXplorer service to simultaneously acquire ultrasonic acoustic and micro-resistivity images –– Provides powerful and complementary information that allows for additional interpretation opportunities while also saving rig time OVERVIEW For more information on how the STAR-HD imaging service can acquire high-resolution resistivity formation images in conductive mud systems, contact your Baker Hughes representative today or visit www.bakerhughes.com/STARHD.
