French major Total and its partners, Qatar Petroleum, Canadian Natural Resources, and Main Street, have made a potentially play-opening discovery with the Brulpadda-1 well, in South Africa’s deepwater Outeniqua basin, about 180 km south-east of PetroSA's Mossel Bay gas-to-liquids plant.
Dr Andrew Latham, vice president, global exploration at natural resources consultancy Wood Mackenzie, said: “Brulpadda was one of Total’s biggest exploration targets this year. The gas-condensate discovery continues the great start for Total's 2019 exploration campaign, hard on the heels of the North Sea Glengorm find, announced last week.
“Even though the well isn’t an oil discovery, if Brulpadda proves to be anywhere near as big as the estimates of up to 1 billion barrels of oil equivalent resources, it will still be a game-changer for South Africa.”
He added: “Brulpadda is also an early validation for Qatar Petroleum’s international exploration strategy. The company has focused exclusively on high-impact deepwater prospects operated by Majors.”
Total plans to follow up the discovery with 3D seismic and wells on up to four more similar prospects on the block, 11B/12B.
Dr Latham said: “If these wells come in too, they can only add to the potential bounty for South Africa.
“This is Total's second bite of the Brulpadda cherry, having suspended its previous attempt at the well in 2014 due to harsh weather. This time around, with a more capable rig, the Deepsea Stavanger, and the weather gods smiling, there have been no such problems.
“The Cape’s metocean conditions could present difficulties for any development, but would be on a par with the West of Shetland, a region Total knows well.”
The discovery could prove a catalyst to restart South Africa’s gas-to-power programme, as well as replenishing gas supply to the Mossel Bay gas-to-liquids plant.
Akif Chaudhry, principal analyst, commodity analytics, said: “While a strong case can be made for the development of the gas economy, long-term growth requires a clear plan from government.”
“We expect the power generation sector to drive gas demand growth. However, at present, all South Africa’s open-cycle gas turbine units are set up to run on diesel. The country’s gas infrastructure is also limited, designed mainly to deliver gas to the Mossel Bay plant and to import piped gas from Mozambique.”
