FracSinus RSM AB offer state of the art stress measurements using both hydraulic and overcoring techniques. Stress data interpretations are also undertaken based on hydraulic data, overcoring data, data resolving from various failures of the borehole wall (drilling-induced fractures, borehole breakouts, slips on re-activated faults). All data interpretations follow the guidelines of the International Society of Rock Mechanics (ISRM).
