, was launched in 1988. It was in use until 2001 when the wireline version of the DeviDrill was introduced. The new version was a big improvement since it allows the drill string to stay in the borehole during steering and coring.

Devico AS has developed their own set of borehole survey instruments to be used together with the DeviDrill. In 2002 a miniature version of the survey tool was launched that made it possible to survey throughout the drill bit.

To survey in magnetic environment, Devico has developed a strain gauge

Strain gauge

A strain gauge is a device used to measure the strain of an object. Invented by Edward E. Simmons and Arthur C. Ruge in 1938, the most common type of strain gauge consists of an insulating flexible backing which supports a metallic foil pattern. The gauge is attached to the object by a suitable...

based survey tool named DeviFlex. This tool became available in 2004.
