Probe, a supplier of cased-hole logging and advanced monitoring technology to the global oil and gas and geothermal industries, has launched the ProMAC, a new series of multi-arm caliper tools. Designed to increase measurement accuracy, reliability and maintainability, ProMAC series tools offer advanced measurements to Source: Probeprovide an accurate profile of the internal surface of tubing, casing and completion assemblies.

The tools join Probe’s growing range of well integrity solutions that help operators identify mineral deposition, corrosion, wear and mechanical deformation. The ProMAC series calipers deliver highly sensitive, accurate multi-arm caliper measurements over a wide range of casing and tubing diameters at a vertical resolution of 0.0001 in with excellent temperature stability.

Transmission of high-density data is made possible by Probe’s digital (HD) telemetry resulting in logs with excellent vertical resolution. According to the company, the new calipers sample at 50 times per second, enabling acquisition of precise log data with high vertical resolution at significantly reduced cost and time frames.

The first in the series, the ProMAC 24 tool, is now commercially available. The 1-11/16 in OD tool accurately maps the internal condition of production tubing, casing and completion jewelry within a measurement range of 1.69 to 7.0 in.
