The year 2008 saw a global financial crisis and a collapse in the price of oil from its earlier highs in the latter part of the year. Not surprisingly, there was an overall decline in exploration activity for conventional oil and gas, although this consisted of a substantial fall in onshore activity partially offset by a modest increase in offshore activity. Activity in the coal seam gas (CSG) sector, on the other hand, continued the rapid growth trend that has been evident in the preceding 2 – 3 years. This sector can now be regarded as having ‘come of age’, and is reported for the first time in this review. Discoveries of conventional oil and gas were concentrated on the North West Shelf and in the Cooper/Eromanga basins, consistent with previous trends. Success rates were highest in the Browse, Bonaparte, Carnarvon and Cooper/ Eromanga basins. A total of 27 discoveries were recorded. In the CSG arena, reserve additions of almost 9,000 PJ were made in Eastern Australia during 2008, primarily in the Surat and Bowen basins. These reserve additions are expected to underpin the development of an LNG export industry in Queensland. Offshore licencing activity was down on 2007, with the Bonaparte and Browse basins having most new permits awarded. There was a resurgence of interest in onshore Queensland and NSW acreage for CSG exploration. Despite the drilling of a number of wildcat wells in frontier basins including the Murray, Darling, Sorrell, Canning and Pedirka, regrettably none was successful.

The geodynamic development of the north–western (Arctic) margin of the Siberian craton is comprehensively analyzed for the first time based on our database as well as on the analysis of published material, from Precambrian-Paleozoic and Mesozoic folded structures to the formation of the Mesozoic-Cenozoic Yenisei-Khatanga sedimentary basin. We identify the main stages of the region’s tectonic evolution related to collision and accretion processes, mainly subduction and rifting. It is demonstrated that the prototype of the Yenisei-Khatanga basin was a wide late Paleozoic foreland basin that extended from Southern Taimyr to the Tunguska syneclise and deepened towards Taimyr. The formation of the Yenisei-Khatanga basin, as well as of the West-Siberian basin, was due to continental rifting in the Permian-Triassic. The study describes the main oil and gas generating deposits of the basin, which are mainly Jurassic and Lower Cretaceous mudstones. It is shown that the Lower Cretaceous deposits contain 90% of known hydrocarbon reserves. These are mostly stacked reservoirs with gas, gas condensate and condensate with rims. The study also presents data on oil and gas reservoirs, plays and seals in the Triassic, Jurassic and Cretaceous complexes.

When visiting Mundesley, in Norfolk, in September, 1916, the present author found upon the shore, in close proximity to an exposure of clay which he now considers to be referable to the Cromer Forest Bed Series, a very finely-made and large flint flake, of human manufacture. This discovery induced him to again visit Mundesley, and during this year (1919) close upon three weeks have been spent in an examination of the stretch of cliffs and shore lying between Trimingham, to the north-west of Mundesley, and Bacton, which lies to the south-east.The author's researches have been greatly helped by the co-operation of three friends, Professor A. S. Barnes, Mr. Walter B. Nichols, and the Hon. Robert Gathorne-Hardy, who accompanied him to Mundesley, and to whom he offers his warmest thanks. He would, however, wish to make it clear that these gentlemen are in no way responsible for the statements made in this paper. For these the author is solely responsible.

As has been shown and extensively dealt with in early and more recent scholarship, Neo-Assyrian palatial wall reliefs went through many thematic changes throughout their two hundred and fifty years of existence. One of their conspicuous traits was a gradual abandoning of magical-religious subject matters, represented by protective supernatural beings, in favour of larger and more detailed historical compositions — mostly of a belligerent nature — revealing, for the first time in antiquity, a truer sense of narrative display. As the narrative-historical themes were rightly considered to be an innovative and prominent contribution of Assyrian imagery to the history of art, extensive efforts have been devoted to the study of these compositions within the context of Assyrian palaces.In the present contribution I intend, however, to concentrate on the “losing” side of Assyrian palatial decoration, namely to focus on the visibility of apotropaic fantastic creatures rendered on wall reliefs and to offer some explanation for their gradual expulsion from the pictorial display of the Assyrian palace. Following Porada, in this essay these hybrids are called demons, in accordance with the Greek term daimon. Benevolent demons appear already in early ninth-century Neo-Assyrian wall reliefs, both in temples, as shown by a small number of slabs from the Ninurta Temple at Nimrud, and much more commonly in palaces, in particular within the North-West Palace.

Power Generation System

Woodside is an Australian oil and gas company and a leading global operator of offshore gas platforms and onshore LNG processing facilities. It is a public company listed on the Australian Securities Exchange headquartered in Perth, Western Australia. Woodside operates the Goodwyn A gas platform on behalf of the North West Shelf (NWS) Project. Woodside assessed Li-ion battery technology and considered the technology mature and ready to be utilised on offshore and onshore operating assets. Woodside operates dedicated islanded gas turbine power generation at each of its onshore and offshore facilities. It was concluded that a large battery energy storage solution (BESS) can deliver several advantages if connected to such an islanded power generation system. The most significant benefit materialises by using a BESS as backup (or spinning reserve) for the gas turbine generators (GTGs). Woodside decided to pioneer the Li-ion BESS technology in a first of its kind application on the NWS Project offshore Goodwyn A gas platform. The Goodwyn A BESS is designed for a 1 MW power and 1 MWh energy capacity, which is considered sufficient to provide the spinning reserve for the Goodwyn A platform. Currently, Goodwyn A operates four 3.2 MW GTGs to provide a typical load of 7–8 MW, with one GTG providing the N+1 spinning reserve. When the BESS is connected to the power generation system, Goodwyn A will operate three GTGs, with the BESS proving the backup in case one of the GTGs trip. The BESS will provide the full 1 MW for a minimum of 1 h, which will give the operators enough time to start the standby GTG or adjust the facility loads (load shedding). The result will be a decrease in overall fuel gas consumption (due to better efficiencies on the remaining GTGs in operation) and a related reduction in CO2 emissions. The project supports the overall objective of the North West Shelf Project to improve the energy intensity of its facilities by 5% by 2020. Woodside believes that developing capability and experience on the installation of BESSs, using Goodwyn A as an early adopter, will facilitate similar and larger installations on other Woodside operated offshore and onshore assets. This is one of the technologies Woodside believes will play an important role to ensure a lower carbon future globally.

Available data for 2018 indicates that exploration activity is on the rise in Australia, compared to 2017, and this represents a second year of growth in exploration activity in Australia. There has been an increase in area under licence by 92 000 km2, reversing the downward trend in area under licence that commenced in 2014. Since 2016, exploratory drilling within Australia has seen a continued upward trend in both the number of wells drilled and the percentage of total worldwide. Onshore, 77 conventional exploration and appraisal wells were spudded during the year. Offshore, exploration and appraisal drilling matched that seen in 2017, with five new wells spudded: two in the Roebuck Basin, two in the Gippsland Basin and one in the North Carnarvon Basin. Almost 1500 km of 2D seismic and over 10 000 km2 of 3D seismic were acquired within Australia during 2018, accounting for 2.4% and 3.9% of global acquisition, respectively. This represents an increase in the amount of both 2D and 3D seismic acquired in Australia compared with 2017. Once the 2017 Offshore Petroleum Acreage Release was finalised, seven new offshore exploration permits were awarded as a result. A total of 12 bids were received for round one of the 2018 Offshore Petroleum Exploration Release, demonstrating an increase in momentum for offshore exploration in Australia. The permits are in Commonwealth waters off Western Australia, Victoria and the Ashmore and Cartier islands. In June 2018, the Queensland Government announced the release of 11 areas for petroleum exploration acreage in onshore Queensland, with tenders closing in February/March 2019; a further 11 areas will be released in early 2019. The acreage is a mix of coal seam gas and conventional oil and gas. Victoria released five areas in the offshore Otway Basin within State waters. In the Northern Territory, the moratorium on fracking was lifted in April, clearing the way for exploration to recommence in the 2019 dry season. With the increase in exploration has come an increase in success, with total reserves discovered within Australia during 2018 at just under 400 million barrels of oil equivalent, representing a significant increase from 2017. In 2018, onshore drilling resulted in 18 new discoveries, while offshore, two new discoveries were made. The most notable exploration success of 2018 was Dorado-1 drilled in March by Quadrant and Carnarvon Petroleum in the underexplored Bedout Sub-basin. Dorado is the largest oil discovery in Australia of 100 million barrels, or over, since 1996 and has the potential to reinvigorate exploration in the region.

The West Sulu Basin lies in the western portion of the Sulu Sea. Republic of the Philippines. It occupies an area in excess of 26,000 square miles (67,000 km2) and is bounded to the west and south by the cordilleran arc extending from the island of Palawan through Sabah and along the Sulu Archipelago to the island of Mindanao. To the north-east, the basin probably extends beyond the edge of the continental shelf in Philippine territorial waters.The basin may be broadly divided into a western platform and an eastern deep: the latter is subdivided by northeast-trending basement ridges into three sub-basins. Sediments deposited in these sub-basins are of Tertiary to Recent age and have been affected by several orogenies and by contemporaneous movements of fault-controlled blocks. This has resulted in truncation and the development of marked erosion surfaces and onlap within the Upper Tertiary section. Many anticlinal features mapped within the basin have resulted from drape over basement highs or from penecontemporaneous growth of these highs.Major unconformities associated with Upper Tertiary tectonic events have been recognized onshore. Extrapolation to offshore areas where these events can be seismically mapped has enabled an interpretative geologic model to be built up. Provisional identification of stratigraphic units and their nature have been made using this model.The Upper Tertiary section within the eastern deep is expected to consist of deltaic and paralic reservoir sands interbedded with, grading into and transgressed by deeper water shale and mudstone with good hydrocarbon source potential. Some limestone lenses may be present.The presence of Lower to Middle Miocene diapiric shale and Plio-Pleistocene intrusives coupled with data of variable quality makes seismic interpretation difficult in some areas. However, several large anticlinal features and a number of stratigraphic and combination traps have been located.A non-commercial discovery of oil and gas has been made in the basin.

The July 2019 magnitude 6.6 earthquake 200 km offshore from Broome is a recent reminder of the significant risk that earthquakes pose to oil and gas infrastructure in Australia. Unlike tropical cyclones, there are no reliable methods for predicting the timing, location and magnitude of imminent earthquakes. Appropriate risk management is therefore required, together with the implementation of emergency response and integrity management procedures, to manage the potential impacts to health, safety, process safety, the environment and production. Given the concentration of oil and gas infrastructure in the north west of Australia, a collaborative approach is advantageous for earthquake risk management and emergency response measures. This paper shares Woodside’s earthquake risk and integrity management procedures with the aim of enabling appropriate quality and consistency throughout the industry. The paper reviews state-of-the-art international practice in earthquake risk management for critical infrastructure from design to operation. Applicable seismic design criteria, likely failure modes and performance requirements are also described. Woodside’s real-time earthquake alert and integrity management systems are presented. Recommendations are made on best practice for earthquake risk management in the region and areas for further collaboration and improvement within the industry.

Detailed Interpretation

Commencing in 2014, Quadrant Energy and partners have undertaken an active exploration program in the Bedout Sub-basin with a 100% success rate, discovering four hydrocarbon accumulations with four wells. The primary exploration target in the basin, the Middle Triassic Lower Keraudren Formation, encompasses the reservoirs, source rocks and seals that have trapped hydrocarbons in a self-contained petroleum system. This petroleum system is older than the traditional plays on the North-West Shelf and before recent activity was very poorly understood and easily overlooked. Key reservoirs occur at burial depths of 3500–5500 m, deeper than many of the traditional plays on the North-West Shelf and exhibit variable reservoir quality. Oil and gas-condensate discovered in the first two wells, Phoenix South-1 and Roc-1, raised key questions on the preservation of effective porosity and productivity sufficient to support a commercial development. With the acquisition and detailed interpretation of 119 m of core over the Caley Member reservoir in Roc-2 and a successful drill stem test that was surface equipment constrained to 55 MMscf/d, the productive potential of this reservoir interval has been confirmed. The results of the exploration program to date, combined with acquisition of new 3D/2D seismic data, have enabled a deeper understanding of the potential of the Bedout Sub-basin. A detailed basin model has been developed and a large suite of prospects and leads are recognised across a family of hydrocarbon plays. Two key wells currently scheduled for 2018 (Phoenix South-3 and Dorado-1) will provide critical information about the scale of this opportunity.
