Stockholm Precision Tools is a leading manufacturer of downhole gyro-surveying systems, borehole survey instruments, and directional surveying and navigation products. SPT products are ideal for the tough conditions and demanding requirements of the offshore/onshore oil and gas industry. Industry professionals around the world rely on our rugged, reliable and accurate downhole measurement and navigation tools to provide outstanding performance time after time.
SPT's product range includes the GyroTracer Directional™ Continuous North-Seeking Gyro and the GyroLogic™ Fiber-Optic Gyro. All these instruments can be calibrated by the operator with the SPT Universal Calibration Stand.
High-speed continuous gyro
The newest product in SPT's GyroTracer range is the GyroTracer Directional North-Seeking, High-Speed Continuous Gyro. This versatile tool can survey a wellbore at speeds up to 150m/min while simultaneously sending data to surface equipment.
The GyroTracer Directional is well suited to offshore applications as it can accurately survey all well profiles, from vertical to horizontal. It is a highly reliable instrument, able to handle continuous surveying at high latitudes or inclinations with no loss of accuracy, and it does not require any surface alignment or calibration prior to use, making it one of the most efficient and flexible gyro instruments available.
SPT's new GyroLogic Downhole Directional Survey Tool uses a Fiber-Optic-based Gyro to find direction. This rugged, easy-to-use instrument can be employed in a variety of offshore applications, including shallow / deep borehole surveying, single shot / multi shot and continuous mode.
The GyroLogic Fiber-Optic Gyro can accurately survey all well profiles at all inclination angles, and can provide directional data (azimuth and dip) at any interval from inside all types of drill rods.
The original GyroTracer Directional North-Seeking Gyro is extremely reliable. Featuring the latest technology, this accurate downhole directional survey and orientation tool uses the gyro-compassing method to find direction.
Unlike other downhole survey tools that use an indirect method or magnetic tools, the GyroTracer Directional North-Seeking Gyro is not affected by magnetic interference so it can be run inside casing, tubing, drill pipes and magnetically disturbed ground.
Downhole gyro navigation
The 42mm diameter GyroTracer Directional™ system is ideal for use in a range of applications in the offshore industry, including shallow borehole and deep borehole surveying, high-speed continuous mode, single-shot / multi-shot applications, slim-hole casing, orientation, whip stock kick-off, and downhole motor orientation.
Supplied with both wireline and memory-mode options, the GyroTracer Directional product is established as a benchmark technology for downhole gyro navigation, and the operating software that runs it is extremely user friendly.
Calibration and testing stand
The Universal Calibration Stand for the GyroTracer Directional is designed for testing and calibration. It is lightweight and hard-wearing, ideal for accurate testing of a range of downhole survey instruments. It is a compact, non-magnetic stand that features advanced design while remaining incredibly easy to use.
The Universal Calibration Stand allows customers to calibrate their tools on site, in just a few hours, saving time and money. It also enables accurate Quality Control checks of instruments in the stand and the option to simulate real situations. Tools can be tested in all inclinations (0-360º), toolface (0-360º) and azimuth angles (0-360º).
Magnetic inclinometers and portable calibration stand
SPT offers a variety of other products, including magnetic inclinometers and portable calibration stand. In addition, our friendly and experienced staff offers ongoing customer support and training so you can be confident that SPT is always on hand to support you.

Case Study: Amuriyah On the afternoon of 23 January 1991, the Amuriyah, an 82,000t Iraqi oil tanker sunk near Bubiyan Island off the coast of Iraq during Operation Desert Storm. In 2013, it was decided the tanker needed to be removed because it was within the tanker turning circle of a proposed mooring point at Iraq's Al Basrah Oil Terminal, through which 97% of Iraq's crude oil is exported.
