Product Description

Optical Borehole Imager 3D Borehole Imaging Optical Scanner 3D HD Borehole lmaging system Borehole Televiewer
In the drilling survey, there is a technique called optical borehole imaging, which examines the internal ground structure and the presence or absence of faults based on the unfolded panorama created by processing the borehole images taken by a camera. 

Optical televiewers (OTV) provide high-resolution, magnetically oriented, color images of the borehole wall.  These images are used to map rock types and orientations of planar features such as fractures, joints, lithologic contacts, and bedding that intersect the borehole.  Most OTV tools use a digital camera directed upward or downward on a conical mirror to collect 360-degree images of the borehole wall. The tools provide continuous images through air- or water-filled boreholes.

The digital, azimuthally oriented image of the borehole wall is split (typically on north), unrolled, flattened, and inspected for structural features. The OTV log represents a map of the borehole wall. The image can be processed and interpreted to identify borehole irregularities and sinusoidally shaped features representing planar features that intersect the borehole  The mid-point depth and orientation (strike and dip) of the planar features can be determined in processing.

The detection and characterization of fractures are important for geologic and fracture network characterization, contaminant investigations, and water-resource evaluations. The location of fractures within a borehole can be used to plan flowmeter, discrete hydraulic tests, and sampling strategies by directing the placement of tools, packers, and or pumps.
