Gyroscope Survey provides accurate and free magnetic interference directional survey in drill pipe, cased holes and production tubing, or in areas of magnetic interference. Altos technologies Gyro inclinometer Survey Tool (GIST) 1 ¾ “ uses inertial grade dynamically tuned gyroscope and state of the art quartz accelerometers in a strapdown configuration to determine hole direction in both orientation and multi-shot surveys, neither the less due to its high accuracy sensors the tool can work in high latitudes and inclinations. Ideal for rigless operation that requires survey most tubing sizes. It also can be run into drill pipes. The flexibility of the design allows the combination with additional services such as Gamma Ray, CCL, Pressure and temperature measurements. Also the survey can be acquired in real time on the conventional wireline cable using our surface telemetry panel and software.
