QL40-OBI-2G
from Mt Sopris
The QL40-OBI tool is a bottom sub of the Quick Link (QL) product line, available for use either as part of a tool string with other QL40 tools or as a stand-alone tool. The OBI40 is the non-stackable standalone version of this tool.
The QL40-OBI tool is designed to complement the ALT Acoustic Televiewers (ABI) in dry wells or clear water environments. It operates with the ALTLogger and MATRIX logging systems and can be run on any standard wireline (mono, 4 or 7 conductor, coax). The tool includes a high-precision deviation sensor (APS544) for accurate image and borehole orientation.
The OBI tool features a high-resolution CCD digital camera with Pentax optics, ideal for fracture detection, thin bed identification, bedding dip analysis, lithological characterization, and determining true rock fabric color. The precise orientation package, which includes a 3-axis magnetometer and 3-axis accelerometer, allows for the correct orientation of images, bedding planes, and fractures to the proper azimuth.
