Murrumbateman, NSW, 2010 Detailed Airborne Survey (P1253), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the Murrumbateman, NSW, 2010 Detailed Airborne Survey survey were acquired in 2010 by the NSW Government, and consisted of 1339 line-kilometres of data at 125m line spacing and 60m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Meda No. 1 Well, Western Australia Of West Australian Petroleum Pty Limited

The Meda No. 1 Well was drilled with WAPET's National 100 rig to the total depth of 8,809 feet. The well was spudded in alluvium, which overlies the Blina Shale to 60 feet. Below the Blina Shale, the Permian sequence was penetrated, consisting of the Liveringa Formation, Noonkanbah Formation, Poole Sandstone with its Nura Nura Member, and Grant Formation. A disconformity is present between the Poole Sandstone and the Grant Formation.
The Grant Formation unconformably overlies the Anderson Formation (Upper Carboniferous) at 4,201 feet. The Laurel Formation (Lower Carboniferous) was penetrated from 4,935 to 5,483 feet. The boundary between the Lower Carboniferous and Upper Devonian (5,483 feet) is tentatively picked at the change from interbedded limestone and siltstone to oolitic limestone. The main objective ofthe test, the Upper Devonian reef complex, was penetrated at 6,620 feet and drilled to the basal conglomerate at 8,360 feet. Precambrian basement was encountered at 8,663 feet. The Permian and Carboniferous sequences could be correlated with the equivalent sequences in The Sisters No. 1 Well. Because of different facies, no formation correlations could be made in the Devonian sequence.
The test resulted in the recovery of several gallons of paraffin-base crude oil. The oil-bearing zone is in the upper part of the Laurel Formation and is confined to a bed of fine-grained slightly porous, calcareous and dolomitic sandstone between 5,125 and 5,133 feet. However because of slight permeability and high water saturation this zone is of no commercial value in this well.
Numerous gas zones were penetrated in the Upper Devonian reef complex but they yielded only weak gas flows, predominantly of methane.
The discovery of hydrocarbons in the Laurel Formation and Devonian reef complex makes Meda No. 1 of great importance in oil exploration of the Kimberley district.
The drilling results show that future oil exploration on the Lennard Shelf should have two main objectives:
(a) structural closures in the Lower Carboniferous
(b) Devonian reef facies.

Outer Darwin Harbour Shallow Water Sediment Survey 2016: Chlorin measurements on seabed sediment.

A benthic sediment sampling survey (GA0356) to the nearshore areas of outer Darwin Harbour was undertaken in the period from 03 July to 14 September 2016. Partners involved in the survey included Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Department of Environment and Natural Resources within the Northern Territory Government (NT DENR) (formerly the Department of Land and Resource Management (DLRM)). This survey forms part of a four year (2014-2018) science program aimed at improving knowledge about the marine environments in the regions around Darwin and Bynoe Harbour’s through the collection and collation of baseline data that will enable the creation of thematic habitat maps to underpin marine resource management decisions.  This project is being led by the Northern Territory Government and is supported by the INPEX-led Ichthys LNG Project, in collaboration with - and co-investment from GA and AIMS. The program builds upon an NT Government project (2011-2011) which saw the collection of baseline data (multibeam echosounder data, sediment samples and video transects) from inner Darwin Harbour (Siwabessy et al. 2015). This dataset comprises porosity and chlorin measurements (concentrations and indices) on seabed sediments.

Special thanks to the skippers Danny Low Choy, Wayne Baldwin, Stewart Weorle and Luke McLaren whose seamanship strongly guided the execution of this survey. AIMS generously allowed use of the aquarium and laboratory at the Arafura Timor Sea Research Facility, and Simon Harries and Kirsty McAllister helped with the setup. We would also like to acknowledge and thank GA colleagues including: Matt Carey, Ian Atkinson and Craig Wintle (Engineering and Applied Scientific Services) for the organisation of field supplies and the design of the new core incubation set-up.
