About FracSinus

 

FracSinus Rock Stress Measurements AB was started in 2016; Daniel Ask has more than 20 years of experience in rock stress and its measurement.

First assignment was with Vattenfall Hydropower AB in 1996, as a MSc student. After completing a licentiate and a doctoral degree at the Royal Institute of Technology (KTH), he received his first permanent employment in year 2006 within the Vattenfall domain. However, at that time, Vattenfall Hydropower AB no longer existed but had changed name to Swedpower AB. As a result of re-organization, Swedpower AB later became Vattenfall Power Consultant AB.

After a few years, VPC AB was sold to the Pöyry group and the new company name became Pöyry Swedpower AB. Daniel stayed two years at Pöyry SwedPower AB before making his first, personally induced change of employer.

He then went to Geosigma AB in year 2014, where he stayed for about 2 years.

During these various companies, Daniel has been working almost exclusively within the field of rock stress measurements. Apart from field measurements, interpretation/analysis, and reporting, Daniel has been significantly involved in various working platform, tool, and instrument developments.

Some parts of the existing stress measurement tools were first developed within the Vattenfall years, but has since been refined, updated, and complemented.

Daniel was the recipient of the Manuel Rocha medal of the International Society of Rock Mechanics for best PhD thesis in rock mechanics year 2006.

Since November 2014, Daniel is adjunct Professor at the department of Exploration Geophysics, Luleå University of Technology. Up to date, most of his work at LTU has been devoted to the ultra-deep stress measurement system to be completed and tested during year 2017.
