Formation and storage conditions of gas hydrate and resource assessment of Ross Sea

doi:10.3969/j.issn.1001-909X.2015.01.003

Abstract

Abstract: The Ross Sea is located on the Pacific side of the Antarctica. Based on analysis of sedimentary, structural and temperature-pressure conditions,it is proved that Rose Sea has good conditions for the reservation and exploration prospects of gas hydrates. In this paper,the heat flow data are used to calculate the thickness of the gas hydrate stability zone. An integral method is conducted to estimate the amount of gas hydrate resources in this region. The results show that the amount of gas hydrate resources of Ross Sea region is 3.6×10¹¹ m³, which means considerable economic value.

Key words: gas hydrates, the Ross Sea, thickness of stability zone, geothermal gradient
