pdf Hydrocarbon potential prospects of D’Urville Sea sedimentary basin (East Antarctica) and adjacent areas based on intercomparison with sedimentary basins located on Australian conjugate margin
Hydrocarbon potential assessment of D’Urville Sea and adjacent cover sedimentary basin based on seismic data, log data of wells and intercomparison with Australian conjugate margin basins is established. A prospect area map is made. There are mapped areas with different hydrocarbon potential prospects. Performance evaluation of sedimentary sequences is done from the perspective of petroleum generation. Thick glacial sediment units were accumulated in D’Urville Sea sedimentary basin, unlike in the Australian conjugate margin basins. Due to the relatively deep burial synrift sedimentary rocks on a large area of the basin got lower than the “oil-gas window”, and the hydrocarbons could migrate into the upper units and accumulate in structural and stratigraphic traps, which is indicated by indirect signs. High hydrocarbon potential prospects are associated with a vast upper Cretaceous sedimentary rocks lens as well as with anticline structures formed by synryft strata.

Keywords: hydrocarbon potential, hydrocarbon potential prospects area map, synrift strata, Cretaceous anticline structure, East Antarctica, D’Urville Sea.
