ATS-A Production Logging Tool

ATS-A

Accelerometer & Temperature

The accelerometer/temperature tool is used to make environmental corrections to logs made by other sensors.

Acceleration data is passed through special processing software to compute the instantaneous deviation in depth from the indicated value provided by the measure-wheel, caused by stick-slip or yo-yo motion of a tool string.

Temperature (internal) is used to correct for thermal expansion of a long tool-string that introduces errors into the depth offsets.

These corrections must be combined with accurate calibrated values of the measure-points for each tool in the string, for maximum accuracy.
