Hydrocarbon exploration and reservoir analysis

In 1850, T. H. Henry published an imperfect analysis of francolite, a supposed new mineral, previously named by H. J. Brooke. Henry stated that his material was similar to the material from Wheal Franco, Tavistock, Devon, but he does not show how he was in a position to know the composition of the material from this mine, because there is no record to indicate that the mineral from Wheal Franco had been analysed. Henry did not report CO 2 for the material he analysed, but M. H. N. Story-Maskelyne and W. Flight analysed material, supposedly similar, and obtained a significant amount of CO 2 .
