Adelaide-based Santos owns the Varanus Island and Devil Creek domestic gas projects in the North West and is developing the Dorado oil field off WA and the Barossa LNG project into Darwin.
Carbon capture and storage
Australian LNG producers are under pressure on emissions and decommissioning, and Santos wants to tackle both problems in one swoop at Bayu Undan, but it needs everyone to play along.
Decommissioning
Santos and Chevron, through Varanus and Barrow Islands, have a big part to play in the clean up of 1000 oil and gas wells in WA, with about 300 ready to be plugged now.
Carbon Emissions
Santos wants to approve its $2.8B Dorado oil project off WA in mid-2022 but science and the law will provide hurdles to its 165 million tonnes of carbon pollution.
Safety
Terrifying video shows an offshore lift that went badly wrong off the WA coast in early July endangering workers hanging off a platform and those on the vessel.
Oil
Santos has "announced" the launch of design work for its Dorado oil project off WA without awarding any engineering contracts. The $2.6 billion project could later supply gas to the mainland.
APPEA 2021 Perth
Santos says attacks on its heavily-polluting Barossa LNG project "should be taken with a grain of salt" but will not substantiate its own claims that emissions have reduced.
Carbon capture and storage
Santos and ENI are looking for solutions for CO2 and removing old facilities in the waters north of Darwin. Time will tell if the problems are solved or just delayed.
Domestic Gas
Santos' Reindeer gas field will fill with water sooner than expected and the production loss will add to concerns about the supply of gas to WA this decade.
Carbon capture and storage
A year after Inpex rejected carbon capture and storage at Ichthys LNG as unaffordable it is an essential element in its new drive to slash emissions by 2030.
Domestic Gas
Chevron, Santos and Kerry Stokes' BCI Minerals are battling in court over responsibility for gas pipelines supplying 40 per cent of the WA market that traverse the $780 million Mardie salt project.
Carbon Emissions
South Korea, Japan and China's tightened climate goals will crunch Australian thermal coal, make LNG investments harder and possibly kill Santos' Barossa LNG project.
Carbon Emissions
Japan's JERA, the major buyer of Australian LNG, has embraced zero emissions by 2050 in another signal that the clock is ticking on this major export.
LNG
Prospects for LNG are under a shadow if Paris Agreement emissions cuts are pursued, according to the IEA, leaving Woodside and Santos in a very dark place.
LNG
Barossa would produce Australia's dirtiest LNG and if other companies will not back it Santos has a very expensive problem.
Domestic Gas
Santos is now the biggest supplier of gas to WA and the future may depend on the Perth Basin after the State's almost four decades of reliance on Australia's first LNG plant.
LNG
Woodside's Scarborough and Santos' Barossa LNG projects unlikely to happen this year as planned according to oil and gas experts Wood Mackenzie.
