Caliper Tool

Severn Subsea Technologies offers a range of calipers to suit different applications.

X-X

Developed to measure the internal profile of downhole valves and inflow control devices the X-X caliper makes two independent radial measurements in the same plane. In addition measurements of well pressure and temperature are made to assist with depth correlation. The standard tool is coiled tubing conveyed and records the data into non volatile memory for later download using Pro-Log.

X-Y

A conventional X-Y caliper for openhole, geothermal applications, 300°C rated. 2-¼” diameter

4, 6, 8 Arm

Multiple independent arm calipers, housing diameters up to 3 3/8″ (86mm), 300°C rated.

Very Large Diameter Caliper

Designed to meet a clients operational specification, the caliper is an example of a project where Severn Subsea Technologies has contributed to the cost of the development and retains full, shared IPR. The caliper is able to measure 3m (118”) diameter pile holes with a 2mm accuracy. Being aimed at the civil engineering industry the tool needs to be robust, easy to clean and as light in weight as possible.
