Confirmation of hydrocarbon gas in offshore Sydney Basin- MEC Resources Limited (ASX:
MMR)
• A hydrocarbon gas source has been analysed and confirmed in the offshore Sydney Basin.
The confirmation of a hydrocarbon based gas analysis was released at the Petroleum
Exploration Society of Australia (PESA) “Eastern Australasian Basins Symposium” 14-17
September 2008.
• The confirmation of this type of hydrocarbon gas seepage is an extremely significant
development for MEC Resources investee Advent Energy, which holds an interest in the
offshore Sydney Basin Petroleum Exploration Permit PEP 11. Active seeps of the nature
reported are considered by experts in this field to occur in basins now actively generating
hydrocarbons and or that contain excellent migration pathways. The methane gas has been
reported by independent testing to comprise a mixture of thermogenic and biogenic gas.
• Hydrocarbon gas analysis has been confirmed to be;
o Methane(CH4) 90.69%
o Oxygen(O2) 1.58%
o Carbon Dioxide (CO2 ) 4.12%
o Nitrogen(N2) 3.7%
• The gas seepage has been observed from repeated sea floor positions in an area off the
coast of New South Wales and along the mainland margin of the PEP11 Permit. The gas is
believed by Advent Energy to be sourced from areas within the PEP11 permit area.
• The area where the gas has been identified is in the same area where oil and gas seeps
have been recorded from Long Reef to Catherine Hill Bay, giving rise to periodic oil slicks
occurrences along the coast , especially in the Cape Three points, Terrigal area. Visible
gas seeps have been audio-visually recorded, and are available to view at
