Paper presented at the 3rd World Petroleum Congress, May 28–June 6, 1951
Paper Number: WPC-4811
... Synopsis Since there is no published work on the slippage characteristics of positive displacement liquid meters and, since such information is needed by meter operators, the author has undertaken a special meter testing project at East Chicago to furnish information. He describes...

... to eliminate the calibration error of commercially available flow meters that depend on the gas type. Nitrogen, helium, and ethane are used in these measurements. Temperature variations of the flowing gas are recorded, and gas slippage and inertia effects are also taken into account. Our study shows...

...), the displacements are in the order of meters, no shear testing device available in the world can impose such displacement records on the samples. Furthermore, there is an issue of wave propagation through rock mass during the shaking induced by earthquakes, which should be carefully considered in this respect...

This study demonstrates that stress magnitudes can be constrained by natural fractures and faults quite locally (at a scale of few tens of meters) and also quite regionally (over km scales). The maximum horizontal principal stresses...
