Borehole Surveying Services
With a successful launch of the LKAB Wassara Surveying Services during 2021, the operation has now expanded outside of Scandinavia. LKAB Wassaras surveying system, the Wassara Explorer™, has now been demonstrated in an international drilling-project in the Italian Alps. It was used for a 300m deep vertical hole.
Background
An International drilling project is taking place in the Italian Alps. The project, DIVE (Drilling the Ivrea-Verbano Zone E), is performed only 3km from LKAB Wassara’s Italian distributors head office. DIVE aims to gain new insights into the characteristics of the lower continental crust through targeted drilling, sampling, and borehole logging.
After contacting the drilling team of DIVE and offering them the LKAB Wassara surveying system, Wassara Explorer™, they liked the idea of performing a demo of the system.

Survey procedure
The drilling-program in the DIVE-project had completed drilling down to 300 meters when it was a good opportunity to survey with the Wassara Explorer™.
The surveying probe was lowered into the hole with the help of a winch on the drill rig. A battery version of the Wassara Explorer™ was used. An accessory in the form of a Bluetooth depth tracker was used to get depth data into the portable field computer that generated the survey results.
Since 2021, LKAB Wassaras is proud to offer Surveying Services globally.
