Depth Logger

Tension values are logged to memory in conjunction with the depth data, and alarms can be set to identify potential downhole problems if tension thresholds are triggered (line going slack or tight).

The surface Depth Logger module, which can be operated in conjunction with the downhole memory production logging tool string has been designed as a safe product. The module can also be used to monitor tension on the slickline.

Tension values are logged to memory in conjunction with the depth data, and alarms can be set to identify potential downhole problems if tension thresholds are triggered (line going slack or tight).
