Morrow, N R

This report presents progress for the second year of a three-year project concerned with the pore structure of low permeability gas sands. The objective of the project is to carry out advanced core analyses on tight sandstones and in particular explain: (1) what structural features cause their permeabilities to often show marked sensitivity to overburden pressure; (2) the superimposed effects of water saturation on gas permeabilities. Contents of this report includes the following sections: (1) multi-core study; (2) difference in permeability between liquids and gases; (3) effect of temperature and overburden pressure on gas permeability; (4) flow in cracks as related to low permeability gas sands; (5) mathematical modelling; (6) relative permeability; and (7) multiwell, special core analyses. 11 references, 31 figures, 27 tables.
