Any angles - upward, downward and horizontal. Boreholes steeper than 45° from the horizontal can be imaged without special settings. Other angled holes require special settings and drillers assistance. For inclined holes, we recommend the hole to be designed 60 degrees from horizontal for stability of the hole.
Optical analysis will require some special preparation for high quality effective imaging.
Imaging can take place in wet or dry holes. However for wet holes, water must be as clear. RaaX utilizes its own prepared flocculent which is effective in de-silting most cloudy water conditions after some hours.
