The HTPF method provides an evaluation of the complete stress tensor, independant of borehole orientation. A section of borehole is sealed off by use of two inflatable rubber. Hydraulic flow is injected gradually raising the pressure until a fracture is initiated in the rock.

description
en The HTPF method provides an evaluation of the complete stress tensor, independant of borehole orientation. A section of borehole is sealed off by use of two inflatable rubber. Hydraulic flow is injected gradually raising the pressure until a fracture is initiated in the rock.
fr La méthode HTPF fournit une évaluation de toutes les composantes du tenseur des contraintes, indépendant de l’orientation du forage. Une section de trou de forage est obturée par l’utilisation de deux obturateurs gonflables. Une injection d'eau est réalisée en augmentant graduellement la pression jusqu’à ce qu’une fissure soit amorcée dans la roche.
