Our in-house caliper tools provide accurate and high-resolution measurements. The measurements troubleshoot issues of inconsistencies in the wellbore. A range of tools is available with temperature ratings from 428°F and 600°F (220°C and 315°C) for oil & gas and geothermal applications. In addition, we have cameras, short-interval gyro surveying, and visualization software to understand better the well. We detect irregularities, deterioration, and leaks inside the tubing or casing early.

Vulcan™ MFT 24

The Vulcan™ MFT 24 can sample 100 times per second with a finger sensor every 15°. For instance, large memory capacity and fast electronics allow higher reporting measurements. In addition, to increase depth resolution for corrosion and pitting detection. Being a lean, compact tool, it can get around high angles, pass restrictions, and log horizontal and vertical wells.

The tool comes in a standard temperature form. The HPHT MFC version – Vulcan™ MFT 24- is good to 428°F (220°C).

Vulcan™ MFT 40

Scientific Drilling’s Vulcan™ MFT 40 was designed and developed specifically for geothermal applications. This geothermal multi-finger caliper delivers high-precision measurements of the internal wellbore diameter. Furthermore, it makes the ultimate casing evaluation technology at temperatures up to 650°F. The Vulcan™ MFT 40 can sample 50 times per second. Therefore, this caliper enables detailed results within hours. For instance, with a finger sensor every 9°, high-speed electronics, and expansive memory capacity.


Scientific Drillings’ close interval survey with a caliper can analyze wellbore geometry in great detail. Our software identifies relative ID restrictions for downhole pumps, such as diameter and length. Meanwhile, combination runs with our multi-finger caliper tool reduce rig time requirements. Furthermore, to ensure accurate wellbore ID information is available for analysis. The explained data allows operators to place better and size downhole equipment. In sum, to avoid subjection to additional stress.
