WebbThe porosity of a reservoir rock is defined as that fraction of the bulk volume of the reservoir that is not occupied by the solid framework of the reservoir. The porosities of petroleum reservoirs range from 5% to 30%, but most frequently are between 10% and 20%. Any porosity less than 5% is very seldom commercial, and any porosity more than ...

WebbHis theory was published in 1915. Even before this, however, he claimed that his theory would make Mach's view of Newton 's bucket correct. He did so in a letter which he wrote to Mach in 1913 in which he told Mach that his view of Newton 's bucket was correct and agreed with general relativity.

The Q-system for rock mass classification, developed at the Norwegian Geotechnical Institute (NGI) in 1974, originally included a little more than 200 tunnel case histories, mainly from Scandinavia (Barton et al., 1974). In 1993 the system was updated to include more than 1000 cases (Grimstad and Barton, 1993).
