Abstract:
Evidence For An Extension Of Active Perth Basin Petroleum Systems
Geoscience Australia has recently completed a marine survey in the offshore northern Perth Basin off Western Australia (Jones et al., 2011a; Jones, 2011b, Upton and Jones, 2011). One of the principal aims of the survey was the collection of evidence for natural hydrocarbon seepage. The survey formed part of a regional reassessment of the basin's petroleum prospectivity in support of frontier exploration acreage Release Area W11-18. This reassessment was initiated under the Australian Government's Offshore Energy Security Program and formed part of Geoscience Australia's continuing efforts to identify a new offshore petroleum province. The offshore northern Perth Basin was identified as a basin with new frontier opportunities. New data demonstrated that proven onshore-nearshore petroleum system is also effective and widespread in the offshore (Jones et al., 2011c). Evidence for a Jurassic petroleum system was also demonstrated in the Release Area W11-18 (Jones et al., 2011c). The marine survey results provide additional support for the presence of an active petroleum system in the northern Perth Basin.
