We perform both optical (Optic Borehole Imaging - OBI) and acoustic (Acoustic Borehole Imaging - ABI) borehole imaging. Typically, OBI borehole imaging is used to locate geological structures such as rock type, mineralogy, fractures, fracture orientations, fracture fillings, etc. in boreholes. Typically, ABI borehole imaging is used to locate geological structures such as fractures, fracture orientations, etc. in boreholes.
Borehole imaging provides significant additional information about rock structures and is often used alongside core samples. Especially if the core is very fragmented, borehole imaging can accurately reveal the rock structures. If the borehole is made by drilling instead of coring, borehole imaging is the only way to obtain information about the rock structures and fracturing.
Optical imaging can be performed in both dry and water-filled boreholes. If the borehole is water-filled, the water must be optically clear. Acoustic imaging always requires the borehole to be water-filled, but the water quality does not matter for the method. Acoustic imaging is also possible through casing.
The sensors we use for borehole imaging are market-leading and have become almost industry standard: ALT's ABI (Acoustic Televiewer) and OBI (Optical Televiewer).
If needed, you can always ask us about alternative equipment. Geovisor has excellent connections with equipment rental companies and a wide network of partners. Our staff has diverse experience with various geophysical equipment.
The customer always receives quality-assured raw data from the measurements. In addition, we perform data processing, analysis, and reporting as agreed.
Reporting at the agreed level and client familiarization with the research results will be carried out as agreed.
