To understand the behavior of clay soil containing gas, it is necessary to know the compressibility and strength parameters derived from field and laboratory tests, as done for clay sediments without gas. For that, ...

The injection of odorant in the gas is a process in the distribution of natural gas which aims to the detection of small gas concentrations for most of the population, warning of possible risks of leaks. In the two Compagas’ ...

This paper analyses the development of spot market gas prices at the TTF gas hub from 2011 – 2014. The long run link of the gas price with the prices of the energy commodities crude oil and coal is evaluated with the ...

A dynamic system for stablishing a known standard gas mixture is necessary for many studies such as development and testing of analytical methods. A permeation tube can be used for this purpose. The work described here ...
