Welltec® Hardware Scanner (WHS)

Reduce uncertainty


We live and operate in a 4-D world, and so should our data. Visualization capabilities have advanced significantly over the years and with good reason. They provide a means of absorbing information intuitively, breaking down knowledge barriers that were previously limited by words.

Welltec has been developing own diagnostic sensors since 2005. Today we have a range of logging tools and own suite of well diagnostics tools, including the Welltec Hardware Scanner (WHS).  

Welltec’s outset is coming from the intervention side – our diagnostics tools aim at improving real-time decision making, increasing understanding of the down-hole environment and adding value to our intervention services.

Read case


The Welltec Hardware Scanner (WHS) is a part of the Welltec diagnostic tools family. It measures the relative changes to the magnetic field caused by the changes in the magnetic surroundings.

Each magnetic field has a unique signature and the WHS can measure the position of completion elements or perforated intervals. It has an integrated accelerometer for tool deviation, orientation and tool movement.
The WHS can be deployed independently or combined with the Well Tractor® for deployment within deviated or horizontal wells.
