Borehole Survey Tools

Sigra has an electronic survey tool module that is based on triaxial magnetometers and accelerometers. It can be configured to record on board at a fixed interval.

Its prime use is in measurement of borehole orientation during or post drilling when it is lowered into the drill string on a wireline. The tool is used in house in Sigra’s stress measurement tools.
