Geochemical Seep Detection for Offshore oiI and Gas Exploration

Australian offshore natural hydrocarbon seepage studies, a review and re-evaluation

“…Water is continuously pumped from the 'fish' onto the survey vessel, where the water is de-gassed and the resulting light hydrocarbons (C 1 -C 8 ) analysed by gas chromatography. Details of this technique have been published (Sigalove and Pearlman, 1975;Sackett, 1977) and results from the North Sea were reviewed by Schiener et al (1985).…”
