Three key elements of future-fit energy super basins – WoodMac
Looking at the future of the oil and gas industry in the sustainable energy landscape, Wood Mackenzie, an energy intelligence group, has outlined three key elements of the energy super basins of the future.
Ever since Russia’s attack on Ukraine, the outlook for the supply, demand, and price of fossil fuels is constantly shifting, which is leading to a rewrite of energy trade flows.
Wood Mackenzie’s research shows that energy super basins of the future must fulfil three key criteria, which entail abundant resources, access to low-cost renewables and hub-scale carbon capture and storage (CCS) opportunities.
The energy intelligence provider points out that the world’s need for sustainable energy is set to change the geography of the oil and gas industry, increasingly entwining it with renewables. Therefore, the upstream industry of the 2030s and beyond must focus on where its synergies with new energies are strongest.
According to a new report by Wood Mackenzie, fewer than 50 traditional super basins supply more than 90 per cent of the world’s oil and gas. These are defined as basins originally holding more than 10 billion boe resources, of which more than 5 billion boe remains.
Andrew Latham, Wood Mackenzie vice president, remarked: “Of the remaining resources from traditional super basins, only 1,453 billion boe or half have been identified as future-fit energy super basins defined as having abundant resources, access to low-cost renewables and hub-scale CCS opportunities.
“The upstream industry of the 2030s will have a different footprint as investment migrates to the new energy super basins. With some basins set to be left behind, the industry will become even more concentrated in its top basins. At the same time, upstream strategies will increasingly merge with low-carbon businesses.”
Wood Mackenzie explains that decarbonising the upstream sector is “the industry’s most pressing sustainability task.” As much of the world’s production is operated by companies with net-zero targets for Scope 1 and 2 emissions by 2050 or earlier, electrifying operations using a clean, renewable energy source is “one of the fastest and best ways to eliminate emissions,” elaborates WoodMac. While the company believes that renewables are easy to install in new fields and retrofitting old ones could be considered, it still underscores that renewable energy sources “need to be plentiful and affordable.”
“The co-location of low-cost renewables with low-cost oil and gas is key. Surplus renewables can also be fed into the grid as part of the overall energy system,” added Latham.
For Westwood, Scope 3 emissions are “the elephant in the room,” as they accounted for more than 90 per cent of oil and gas emissions of 18.5 billion tonnes per annum (Btpa) CO2e in 2021, representing over half of the world’s total energy-related emissions.
The energy intelligence firm outlines that Scope 3 emissions can be reduced directly by cutting production or indirectly via sequestration or offsets, with CCS being the most promising sequestration technology. This is because it offers the scale to decarbonise difficult-to-abate consumer sectors and could save 18 per cent – with direct air capture – of annual global emissions by 2050. Moreover, CCS does not need to be in the same basin as oil and gas production, but in practice is unlikely to be located away from upstream operations, underlined WoodMac.
Furthermore, all existing planned and hypothetical CCS projects add up to just under 1 Btpa CO2 total capacity, concentrated in a handful of countries, largely reflecting the location of commercially feasible CO2 point sources rather than the limited availability of subsurface storage resources, emphasised the energy intelligence provider.
“We expect global CCS capacity to grow to between 2 Btpa and 6 Btpa by 2050. Exactly how and where this will happen is unclear. Our assumption here is that this growth will come mainly from countries that will have hub-scale emissions sources available close to subsurface storage options. CCS operators will offer sequestration as a service to emitters,” stated Latham.
To identify basins best placed to make the transition, Wood Mackenzie has created a simple scorecard approach using clean electricity and CCS indices. While some are obvious candidates, scoring highly on all criteria, the company says that others look “much less attractive.”
“These scores are not set in stone. Plenty of basins currently sit somewhere in between energy super basins and disadvantaged basins. Host governments may have opportunities to improve the outlook of a basin. Carbon taxes and other fiscal and regulatory moves to accelerate decarbonisation – especially where they enable CCS – could play an important role and should be seized where possible,” elaborated Latham.
In lieu of this, some good examples of future energy super basins include the Gulf Coast and Permian in the U.S., the Rub al Khali in the Middle East, the North Sea, and Australia’s North Carnarvon. However, Wood Mackenzie claims that more work needs to be done as half of the world’s remaining resources in traditional super basins are “disadvantaged.”
The energy intelligence group further stated that the U.S. Gulf Coast and Permian basins are both energy super basins, offering “plentiful” clean electricity from “excellent” solar power potential and additional renewables from wind. As a result, Wood Mackenzie expects a “substantial” CCS industry to emerge, based on hub-scale CO2 sources from refining, petrochemical and other industrial facilities around the Texas coast.
“Recognising the long-term direction of travel presents an urgent call to action. It will take many years, even decades, to fundamentally realign global upstream portfolios with the new energy super basins. First-mover advantage applies. The sooner the transition starts, the better,” concluded Latham.
