Stockholm Precision Tools - Gyroscopic and Magnetic Borehole Surveying Instruments, and Downhole Survey Tools

Stockholm Precision Tools (SPT) is a customer-driven company committed to total customer satisfaction for precise measuring tools for use in the petroleum exploration and mining industries.

The Stockholm Precision Tools name is well-known for its downhole gyro-surveying systems, borehole survey tools and subsystems used for directional surveying and navigation, including the new wireline and memory mode north-seeking gyro tool, GyroTracer™.

SPT's research and development team continues to focus on designing and manufacturing highly versatile survey tools, and the software to drive and support these systems.

Reliable and accurate downhole measurement tools

Through extensive development and field testing, Stockholm Precision Tools manufactures magnetic inclinometers and north-seeking gyro surveying tools that deliver highly accurate data for acquisition and analysis.

SPT systems are advanced, rugged, reliable and accurate downhole measurement tools designed for the global resources industry. From oil and gas wells to base and precious metals mining operations, our borehole downhole navigation tools are trusted across the globe.

We realise the increased demand for wells to be drilled to greater depths with more complex trajectories. Our systems are the right solution for your needs. SPT's target is to become one of the top three players in the industry using the momentum established by the company's new GyroTracer, a north-seeking gyroscope.

North-seeking gyroscope

The GyroTracer instrument is a highly accurate, extremely reliable downhole directional survey and orientation tool. Comprising the latest technology, the SPT system uses the gyro-compassing method to find direction.

As it is a north-seeking gyro, all measurements are in reference to geographic north and measures earth’s rotation directly. Unlike other downhole survey tools that use an indirect method or magnetic tools, the GyroTracer is not affected by magnetic interference. It can be run inside casing, tubing, drill pipes and magnetically disturbed ground.

Downhole directional survey and orientation tool

The easy-to-use, 42mm diameter GyroTracer system can be used for a variety of applications including shallow borehole to deep borehole surveying, single-shot / multi-shot applications, slim-hole casing, orientation, whip stock kick-off, and downhole motor orientation. The operating software used to run all SPT instruments is very reliable and user friendly.

The GyroTracer package comes with both wireline and memory-mode option. It has become recognised as a benchmark technology when considering downhole gyro navigation.

Multi-shot magnetic inclinometer

The MagCruiser™, the world's most robust drop-capable magnetic inclinometer, is a memory-surveying instrument with drop capability that provides magnetic azimuth along with inclination, tool-face and magnetic field readings. It is designed for the rugged design of the mining industry and has a temperature rating up to 125°C.

A single survey allows the operator to measure the azimuth, inclination, toolface and magnetic field at one depth. Multi-shot mode allows the operator to take many surveys at any depths to find information on the hole path and coordinate positions. This can be done on run-in, run-out, or both. The instrument is not run on a timer so survey shots can be taken at any depth or time. The software enables the user to run surveys on-line or off-line.

World-class north-seeking gyro servicing and systems

SPT's other products include magnetic inclinometers with various diameters for different applications, portable calibration stands and wireline winches. We are one of the only north-seeking gyro manufacturers in the world that offers sales, rental and service of all our products.

With our experienced staff offering ongoing, non-stop customer support and training, the customer will always be working directly with the manufacturer and can always be confident when running SPT systems.

Gyro survey instruments for borehole applications

Choosing the correct gyro survey instrument can be a difficult decision for those with limited knowledge of gyros. We can help you make the right decision due to our years of pioneering R&D and our expertise and knowledge within the industry.

The GyroTracer provides continuous reliable and accurate data for all types of borehole profiles due to the high sensitivity of a spinning mass gyro and its design. It can be utilised for various applications for the end user, including:

• Borehole directional surveying
• Wedge and motor orientation
• Side tracking
• Collision avoidance
