Optical imaging is based on the use of optical camera technology in bore hole. Typically, method is used for locating geological structures such as rock type, mineralogy, fracturing, fracture directions, fracture filling etc. in the bore hole. Acoustical imaging is based on the use of acoustic camera technology in bore hole. Typically, method is used for locating geological structures such as fracturing, fracture directions, etc. in the bore hole.
Borehole Imaging data provides additional information to be used along the core sample. Especially in case of core loss the borehole imaging provides additional data. If hole is done by percussive drilling instead of core drilling, imaging can provide important additional information. Unlike traditional video scans, the images created by our imagers are full 360 degrees and accurate in all measures, allowing accurate measurement of things such as fracture orientation and -size.
Optical imaging requires optically transparent water fill in the bore hole, whereas transparency is not required in the case of acoustic imaging. Acoustic imaging requires the presence of water in borehole. Imaging can be done down to depth of 2400 meters. Borehole diameter can vary from 46 mm (optical) to 200 mm.
Please, see our comprehensive Borehole Imaging equipment from equipment listing. If you can’t find desired geophysical or any other equipment from our selection, please let us know. We have excellent connections to rental agencies and pools. Our crew has comprehensive experience of various geophysical equipment.
Client will always receive quality assured raw data from the loggings. Additionally, we are able to do processing, analysis and reporting of the results (e.g. picking fracture depths and orientations).
Reporting to requested level as well as orientation of the client to the survey results will be done as requested
