The share of global hydrocarbon production from ‘aging’ assets is increasing, whereas global demand for energy continues to increase at 1–2% per year (IEA 2019). In 2018, the International Energy Agency estimated the global average production decline at 4% per annum (Gould and McGlade 2018). Production from many of Australia’s established basins, such as the Cooper–Eromanga basin and the North West Shelf, is dominated by aging assets. To arrest this decline, actions must be taken to meet global demand for oil and gas, sustain production and underpin shareholder expectations of a return on their investment. Arresting field decline is a multifaceted problem. A single fix, whether technological or operational, will not maximise production or asset value. Any project to arrest field decline, grow production or (re)develop a field must be considered in its entirety, as an integrated system, by a multidisciplinary team. In addition, and critical to success, the required outcome must be clearly established and committed to by field owners, consultants and staff assigned to the project. This paper demonstrates how using a committed, outcome-focused approach, an integrated project team identified field redevelopment opportunities that significantly increased estimated ultimate recovery in an aging oilfield (that had already produced more than 70–80% of the developed resource) in the Cooper–Eromanga basin, South Australia. Factors critical to success were: (1) a commitment to look at all aspects of the field, from geology and geophysics, through the completion, well and field performance and operational infrastructure to identify development opportunities; (2) an ability to be agile, cycling quickly through the workflow as new information became available; (3) dedicated resources, clear communication and a commitment to integrated work across consultant and staff resources; and (4) management support.

Subject Long-term energy markets outlook. Significance The International Energy Agency (IEA) has upgraded its forecast for total primary energy demand (TPED) to 2040 for the first time since it began projecting this far out in 2014. Impacts The IEA’s belief that the world is on an environmentally unsustainable path will bolster decarbonisation efforts nationally and globally. The IEA does not see oil demand peaking by 2040; this and gas’s growing share of global demand will help sustain oil and gas investment. China and India switching from coal to gas will reduce coal’s share of energy demand even though India’s official targets are optimistic.

Oil Seepage

The Geltwood Beach (buried) anticline is located near the ocean coast in south-east South Australia, directly west of the agricultural and industrial town of Millicent. The structure is developed in Mesozoic to Tertiary sediments forming the inner part of the continental sedimentary terrace which in this situation coincides also with the Nelson "half-graben".The Geltwood Beach anticline is more than five miles long by two or more miles wide. It is part of a still larger regional development which pitches south-east into the deeper known portions of the Gambier-Otway Cretaceous to Tertiary Basin. There is no surface expression to the structure.Structural "closure" on the base of the Tertiary may not exceed 100 feet, but an extensive area of structural flattening along the crest of the anticline (defined by structural drilling and geophysical techniques) overlies a zone of extensive sedimentary wedge-out within the predicted and prospective cretaceous sediments in depth. The wedging is predicted to be in the nature of progressive overlap onto structural "nosing" or alternatively, buried-ridge development in presumed Otway Group sediments in depth.A thickness of 5,000 to 8,000 feet of unconsolidated Upper Cretaceous to Tertiary sediments, wedging to the north-west along the crest of the anticline in the deeper developments is expected to include the prospective Belfast Mudstone equivalents and related beds of the Port Campbell (Victoria) Association.The Geltwood Beach structure lies approximately half way between the Mt. Salt No. 1 and Beachport No. 1 wells. In the distance of 45 miles between the latter wells, the dominantly Cretaceous (post-Otway) sedimentary section wedges spectacularly from 7,000 feet (possibly considerably more) to no more than 100 feet. The available geophysical evidence suggests that most of this wedging occurs within the zone of the Geltwood Beach anticline. For this reason, the anticline is believed to be well located for the development of structural and stratigraphic traps in a marginal continental shelf environment of proven thick sedimentation.In the Mt. Salt No. 1 well, clays and shales encountered at at least five stratigraphic levels within the Lower Tertiary to Middle Cretaceous section provided adequate capping to underlying highly porous and permeable reservoir sands, the lowermost of which were brine-bearing.Geltwood Beach is a locale of preferred coastal bitumen stranding. The weight of published evidence now points to nearby submarine seepage within the reach of erosive storm waves: recorded earthquakes in this vicinity are known to have greatly affected the activity of these seepages.The conclusion is reached that the Geltwood Beach anticline is favourably situated up-dip on the inner continental shelf margin to accumulate hydrocarbons in potentially commercial quantities. The structure lies south of the Beachport-Kalangadoo "hinge-line" of the Nelson half-graben in a zone of submarine oil seepage. A proposed deep test well to be located near the culmination of shallower structure is expected to provide a satisfactory test in respect to both structural and (to a lesser extent) deeper stratigraphic entrapment of petroleum.

Short Supply

This Petroleum Exploration Society of Australia review looks in detail at the trends and highlights for oil and gas production and development both onshore and offshore Australia during 2017. Gas production soared while oil production plummeted yet again. Liquefied natural gas (LNG) did well; 2017 was a great year for LNG and 2018 should be even better. There are stark contrasts between domestic gas on the west and east coasts. On the west coast, prices are affordable and supply relatively plentiful. On the east, prices are high and gas is in short supply. This paper canvasses these trends and makes conclusions about the condition of the oil and gas industry in Australia. This paper relies primarily on production and reserves data compiled by EnergyQuest. In its latest review of Australian energy policy, the International Energy Agency comments yet again on the weaknesses of Australian oil and gas statistics. This paper also makes some observations on these weaknesses.

2022 SPE President Kamel Ben-Naceur Kamel Ben-Naceur is CEO of Nomadia Energy Consulting, where he advises on sustainable energy policies and global and regional energy economics and outlooks. He has worked as the chief economist for a major oil and gas company and for an oilfield services company. Ben-Naceur has also worked as a director of the International Energy Agency and as the industry, energy, and mines minister for the Tunisian government. He has chaired several SPE global committees, including Business Management and Leadership, the International Forum Series, and CO2 Capture, Utilization, and Storage. He has also taught several SPE courses on global energy and strategic thinking and planning. He was technical director for the Management and Information discipline on the SPE International Board of Directors from 2008 to 2011. Ben-Naceur was also an SPE Distinguished Lecturer during the 2009–2010 season and received an SPE Distinguished Member Award and SPE Distinguished Service Award in 2014, the AIME Charles F. Rand Memorial Gold Award in 2019, and the 2020 Sustainability and Stewardship in the Oil and Gas Industry Award. He has coauthored more than 150 publications and 17 books. Ben-Naceur holds the Agrégation de Mathématiques degree from the École normale supérieure and a master’s degree in engineering from École Polytechnique in Paris. What key issues will you emphasize as 2022 SPE President? Our industry, along with many other economical sectors, has experienced a major impact from the pandemic. The magnitude of the drop in oil demand in 2020, both in absolute and relative terms, is unprecedented. It led also to a major reduction in oilfield investment activity around the world, in the order of 30% compared to pre-COVID-19 levels. The fast-track development of vaccines and their availability, even though progress is still required to ensure that they are distributed fairly around the world, is raising hope that the worst may be behind us. SPE members have also been impacted in their ability to meet at technical conferences and exhibitions and participate in workshops or forums. As 2022 SPE President, the theme I wish to develop is the “sustainable recovery” for our industry and for SPE. The industry has experienced in 2020–2021 a major loss of valuable employees ranging from young professionals to senior members. This has followed a major downcycle in 2014–2015. After a 30% drop in Capex in 2020 compared to 2019, 2021 should see a modest recovery in activity (6–8% increase). The next year should welcome a 10–12% activity surge, providing an increase in employment opportunities for our members in transition, as well as for our student members. Barring new negative developments in the pandemic, the recovery in activity should strengthen to reach pre-COVID levels by 2025, albeit 15–20% below the level that was expected before. The recovery of demand and activity should also be linked to a more sustainable trajectory of energy demand and supply. Sustainability will be my second area of focus, with SPE having already engaged significantly. I had the opportunity to participate in the startup of the SPE GAIA Sustainability Program, which is now developing into many different directions, thanks to the efforts of SPE volunteers. 2019 SPE President Sami Al-Nuaim had put sustainability at the heart of his presidency, and I am pleased to see several of his initiatives materialize. The third area of focus will be a gradual restart of physical meetings, where we will transition with the increase of hybrid (in-person/virtual) events, which is eagerly anticipated by our members. The fourth area of focus is related to the development of the new SPE Strategic Plan. Last but not least, is the proposed merger between SPE and the American Association of Petroleum Geologists (AAPG).

The Impact

Subject Gas market outlook. Significance The price of spot liquefied natural gas (LNG) fell at end-February to the lowest level since July 2009. Long-term forecasts for global gas demand have been downgraded by the International Energy Agency (IEA) and by oil and gas companies, such as BP and ExxonMobil. US demand is rising, while production growth appears to have flattened. However, the impact on prices will be limited in 2016. Impacts Gas companies' revenues will be pressured, with pipeline suppliers in Europe discounting prices to compete with LNG imports. With uncertain prospects for gas in power generation, companies will focus on new opportunities in transport. Gas industry groups will seek carbon regulations that support gas rather than penalise fossil fuels to the advantage of renewables.

There is currently a strong UN and IPCC-led campaign promoting the rejection of oil-derived fuels because of the risk of global warming. However, global demand for oil does not decline, but tends to increase to 100 million barrels per day in 2018 according to the International Energy Agency (IEA). This clearly demonstrates that a speech is not enough, but new sources of energy are needed that can unequivocally replace oil from a technical and economic point of view. In this context, one of the possible solutions is the introduction of biorefineries, which have the capacity to process biomass from different sources, generating several products and fuels derived from biomass. An example of biorefinery is the production of ethanol from sugarcane bagasse, where all sugarcane biomass is harvested for ethanol generation. However, the processes involving biorefineries are still in laboratory or pilot scale, because these processes are not yet economically feasible. One of the crucial bottlenecks of a biorefinery is the energy cost of the processes involved, which is often greater than the energy gain obtained. One way to reduce the energy costs of these processes is thermodynamic optimization. For this, mathematical models are needed that are capable of describing all the processes that occur within a biorefinery. Unfortunately, there is no such tool available, which makes thermodynamic optimization of biorefinery impossible. However, for oil refining, this tool is already available even in the form of commercial software such as Aspen Plus, after all petroleum refining is an industry more than a hundred years old and so the exploitation of oil is so profitable. If biorefineries want to compete with the oil industry, it is necessary to develop simulation tools that can be used for thermodynamic optimization, so that the processes of a biorefinery become economically feasible.

The Impact

"A warm start to the year 2020 coupled with the impacts of the COVID-19 pandemic had a devastating impact on the Oil and Gas sector across the globe. A great economic shock was felt throughout this period and continued until the end of the year and even during the next year, but the extent of the damage is still uncertain, as is the speed and scale of recovery. Owing to the global lockdowns that resulted from the COVID-19 pandemic, gas consumption and production plummeted and the prices reached a new record low. As the pandemic started to spread in Europe the gas production went below the 2015-2019 range reflecting the decreasing trend of gas production in EU. In the same period 5 years ago the gas production was 36.6 bcm, more than twice as in Q1 2020, illustrating the rapid decrease in gas production in the block of 27 and the increase in import dependenc in natural gas. This study highlights the effects of COVID-19 on the gas markets based on publications of National Regulatory Authorities, Transmission System Operators, International Energy Agency, one of the world’s most trusted providers of data of global commodities markets and European Energy Exchange. Under the optimistic infection scenario, gas demand will recover close to the non-pandemic level by 2021. Unfortunately, the oversupply situation is improbable to be overcome promptly and in a more pessimistic way there is no visibility for a better business environment before 2023. "

Offshore exploration commonly uses geochemical sniffer technologies to detect hydrocarbon seepage. Advancements in sniffer technology have seen the development of submersible in-situ methane sensors. By integrating a Franatech laser methane sensor onto an autonomous underwater glider platform, geochemical survey durations can be increased, and associated exploration costs reduced. This paper analyses the effectiveness of methane detection using the integrated system and assesses its practical application to offshore hydrocarbon seep detection methods. Blue Ocean Monitoring surveyed the Yampi Shelf, an area with known oil and gas accumulations, and observed hydrocarbon seeps on the North West Shelf of Australia. Results from the survey showed a background dissolved methane concentration of 3 to 4 volumes per million (vpm). A distinct plume of methane between 30 to 84 vpm measured over 24 km2 was detected early in the survey. Three smaller plumes were also identified. Within a small plume, the highest concentration of methane was detected at 160 vpm. Methane above background levels was observed within 8 km of previously identified seeps; however, these seeps were unable to be pinpointed. Comparisons with data from previous surveys suggest similar oceanographic influences on the behaviour of the seeps, including tidal variations and the position of the thermocline. The results demonstrated that the integrated system may be used to effectively ground truth remote sensing interpretations and survey areas of interest over long durations, providing methane presence or absence results. To this effect, the integrated system may be implemented as a supporting technology for assessing the risks of further funding hydrocarbon detection surveys and focusing the area of interest before the deployment of vessel-based surveys.

The region of Australia comprising the area of the NT and northwest Queensland has significant conventional and shale resources that can see it emerge as the next major global oil and gas hub. According to the International Energy Agency (IEA), in the Asia-Pacific region, the natural gas production-consumption shortfall is expected to grow from 99.8 million tonnes per annum (mtpa) in 2012 to 251.7 mtpa in 2025 (IEA, 2014). Australia is well-positioned to cater to this growing demand, and is set to become the world’s largest LNG exporter by 2020. The northern Australia region can help to meet this growing global demand and also serve domestic east coast demand. Development of these resources would significantly accelerate the regional and national economy, but success will depend on doing it at a cost that is competitive with new sources of hydrocarbons from around the world. This extended abstract outlines the natural advantages and challenges being faced by operators seeking to develop this region of northern Australia. Drawing on insights from global experiences, it identifies the key success factors and challenges faced in different regions during their development and commercialisation. It provides guidance and recommendations for maximising the development potential in northern Australia including: new ways of working; industry collaboration including sharing of infrastructure and data; service provider development; commercial partnerships; better access to capital; and, government support in tenure reform, incentives, tax benefits, capability development and investments in infrastructure.
