The predicted temperature distribution was confirmed experimentally using a double pyrometer set-up, one focusing on the outer die wall surface and one on the bottom of a borehole in the upper punch.
These modifications allowed observing the process of debonding of sand grains from the borehole wall during the test and consequently, acquiring a better understanding on the failure mechanisms of a borehole drilled through poorly cemented sand formations.
Koizumi et al. (2016) analyze a groundwater-pressure monitoring record maintained from 1998 on at a borehole 10 km southeast of the summit.
His landlord runs a power line into the slum for electricity and draws water from a borehole on the property.
We have observed anthropogenic secondary minerals on borehole walls using a borehole televiewer (BTV) in boreholes drilled into granitic rock.
At Tilshead, a borehole on Salisbury Plain, groundwater levels rose by 20m in a fortnight from the end of December to early January, he says.
Pastoralists tend to locate their limited livestock-related equipment (livestock and vaccination pen, wells and a borehole) on the attachment territory.
We investigated the effect and magnitude of these perturbations on large drill core samples (12 20 cm long, 5 cm diameter) of high-grade, granitic gneisses obtained from 350 to 600 m depth in a borehole on Olkiluoto Island (SW Finland).
Itoh and Tsuru (2006) reported paleomagnetic directions from a borehole on the forearc (MITI Sanriku-oki in Figure 1), which are suggestive of clockwise rotation since the Eocene, and proposed a tectonic model of forearc slivers divided by dextral faults.
The fractured granite is 20 m thick (Mizoguchi et al. 2008) based on surface samples around this area, and the thickness of the permeable zone has been estimated to be 15 25 m (Lockner et al. 2009) based on core samples from a borehole drilled 4 km northeast of our study site.
