OrWell 120 – Digital Well Orientation String / Mess-Stab für Bohrung
Messgerät für Bohrlöcher bzw Bohrlochorientierung
Digital Borehole Orientation logging string is designed to give accurate information about
orientation of the well: Azimuth (Heading), Inclination (Pitch) and Relative Bearing (Roll). It
can be utilized in Open Hole and (metal or plastic) Cased Hole environment using monoconductor
cable. The OrWell 120 is continuous north seeking type of tool and measuring
could be performed in vertical or horizontal well with appropriate equipment (centralizers,
tractors, coil-tubing, semi-rigid cable).
The full system includes the downhole tool string and our Acquisition System WellScan
LS730 with software for data management, analysis and presentation of collected data. The
string itself is fully compatible with SDS Warrior Acquisition System.
