Ten papers were presented at the Deep-Source Gas Workshop. Laser papers are included in this proceedings under the following headings: (1) abiogenic origin of deep source gas; (2) geochemical and thermodynamic studies of deep source gas; (3) detection and differentiation of deep source gases; (4) deep sedimentary basin gas; (5) deep source gas associated with tectonic processes at convergent margins. All papers have been abstracted and indexed for the Energy Data Base. (ATT)
