Our in-house developed caliper tools provide accurate and high resolution measurements of wellbore anomalies to troubleshoot issues. A range of tools are available with temperature ratings of 428°F and 600°F (220°C and 315°C) for oil & gas and geothermal applications respectively. In support of the caliper we also have cameras, short interval gyro surveying, and visualization software to best understand the well for early detection of deformities, corrosion and leaks inside the tubing or casing.

Vulcan™ MFT 24

With a finger sensor every 15°, large memory capacity and fast electronics, the Vulcan™ MFT 24 can sample 100 times per second.  This allows for superior profiling measurements, and enhanced depth resolution for corrosion and pitting detection. Being a slim, compact tool it can get around high doglegs, pass restrictions and log horizontal as well as vertical wells.

The tool comes in a standard temperature guise as well as the HPHT MFC version – Vulcan™ MFT 24 which is good to 428°F (220°C).

Vulcan™ MFT 60/90

Scientific Drilling‘s Vulcan™ Multi-Finger Tool (MFT) 60/90 provides reliable and accurate data on the condition of the casing in high temperature wells (up to 600°F/315°C).  The tool extends 60/90 fingers to measure the minimum and maximum internal diameter of the casing, ranging from 5 ½” to 18-5/8” casing diameters. The Vulcan™ MFT 60/90 is fit for the purpose of the majority of very hot geothermal applications.

DuraSet

Scientific Drilling‘s close interval gyro survey in conjunction with caliper can analyze wellbore geometry in exceptional detail. Our software identifies relative ID restrictions for a given down hole pump diameter and length. Combination runs with our multi-finger caliper tool reduces rig time requirements, and ensures accurate wellbore ID information is available for the analysis. The interpreted data allows operators to better place and size downhole equipment to avoid subjection to additional stress.
