  • The first phase of a comprehensive study of source rocks and oil fluid samples in the foreland and Papuan fold belt.
  • Open file samples from the PNG Department of Petroleum and Energy (DPE).
  • Samples were obtained from Geoscience Australia in Canberra, from the Kestrel Laboratory in Melbourne, and from the Weatherford Laboratory in Brisbane
  • Samples sent by participating companies.
  • Open file rock samples (core, side wall core, drill cuttings) gas and oilseep samples, geophysical and geological logs, data and reports.
  • Using these resources and published data, EGI created a comprehensive data base. Analytical work has been conducted at EGI’s organic geochemistry lab which houses a state of the art HAWK™ pyrolysis instrument. The HAWK™ instrument offers greater precision in free hydrocarbon measurement and better repeatability than previous generation instruments and the complementary suite of instruments provides full quantification of the petroleum system elements.
  • 60 wells were sampled in the foreland basin and parts of the fold belt for a basic HAWK™ analysis.
  • 28 analyses of oils and seeps.
  1. Digital & Printed Report
  2. 1900 HAWK Analyses
  3. Pyrolysis & Pyrograms from 60 wells
  4. Analyses & interpretation from 28 oil samples
  5. Maps, Cross-sections & Selected Well Montages
  • Use modern potential field data to redefine basin architecture, new play types, source rocks and reservoirs in the southern (foreland) sections of the Papuan Basin covering parts of Papua New Guinea (PNG), Indonesia and Iran Jaya.
  • Define and quantify source and reservoir potential using available open file samples of outcrop, shallow boreholes, drill cores, side wall cores and drill chips
  • Define and quantify available oil and gas samples from existing oil well samples and oil and gas seeps in situ
  • Evaluate the geological controls – stratigraphic and paleoenvironment – parameters of source and reservoir intervals of the southern Papuan Basin
  • Quantify the geochemical, petrophysical and geophysical attributes of the source rock and reservoir intervals of the southern Papuan Basin
  • Evaluate the gas/liquid potential of the southern Papuan Basin
  • Assess potential gas/liquid resources in place

The Papuan Basin stretches across Papuan New Guinea (PNG), West Papuan (Indonesian) and Australian territory and territorial waters. The basin has a long exploration history but remains largely underexplored. The basin is bounded to the north and northeast by basement highs, comprising igneous and metamorphic rocks of the Central Highlands and Owen Stanley Ranges. To the south, the basin boundary is not well defined and is contiguous with the Carpentaria Basin toward the southwest.

The basin was initiated during Permo-Triassic rifting of the northern margin of Australia. Long-lived passive margin sedimentation occurred before compression in the Neogene after collision of the Australian Plate with the Melanesian Island Arc. This resulted in the formation of the present-day fold and thrust belt, site of many commercial hydrocarbon fields. Rifting in the Late Cretaceous led to the opening of the Coral Sea Basin and another contemporaneous ocean basin to the north during latest Cretaceous to Eocene time.
