CSIRO Petroleum in Melbourne, Australia, welcomes applications to a Postdoctoral Fellowship
in hydraulic fracture stimulation mechanics. The successful candidate
will have a background in applied mechanics and numerical methods with
an interest in verifying numerical calculations by experiment.  The
research results will be applied to stimulation of hot fractured rock
geothermal reservoirs.

 It seems that within the field of fracture mechanics, some authors use "fracture" to refer to the mechanism of creating new surfaces within a body by breaking the material bonds and reserve the word "crack" for the sharp-tipped discontinuity that results from fracture of a brittle material. But it does not appear that this distinction is followed consistently throughout the literature, and perhaps different research areas within the fracture mechanics field use the two words in different ways.

The post doctoral fellow will be engaged in research on the mechanics of hydraulic fracturing of rock. The primary aim of this project is to investigate, using a novel approach for experimentation spanning laboratory and field scales, the effect of fracture size on the energy required for fracture extension in rock.

CSIRO Petroleum (www.csiro.au/org/cpr.html) is an independent supplier of
R&D to Australia's oil and gas industries. Research covers the development
of oil and gas resources, from exploration to production. The Division seeks to
employ a Post Doctoral Fellow within the Hydraulic Fracturing group, which is
based in Melbourne, Australia. The Post Doctoral Fellow will be required
to work on a project to develop a new capability in hydraulic fracture
monitoring and to investigate the effect of scale on the fracture toughness of
rocks. We are seeking a flexible individual with skills in the areas of
geophysical methods, inverse problems, and rock/fracture/fluid mechanics.
