NEW UPSTREAM Article Post 1 - Orange basin is gold21 Aug 2023 11:52
I've not copied the article, but summarised it here.
Shell and TotalEnergies have unearthed a minimum of 11 billion barrels of light oil along with up to 8.7 trillion cubic feet of gas in the Orange basin in Namibia over the past year and a half, as confirmed by leading petroleum authorities in the nation.
These remarkable figures, revealed recently, emphasize the understanding that this new geological zone's hydrocarbon capacity — extending also into South African waters — equates with the offshore regions of Guyana, where ExxonMobil discovered enormous reserves.
Derived from just a few exploration and assessment wells, these estimates were highlighted at an essential upstream gathering in Windhoek last week by Maggy Shino, Petroleum Commissioner at Namibia’s Ministry of Mines & Energy, who stated, “The Orange basin's potential is only beginning to be uncovered.”
Currently, attention is on Namibia's substantial oil findings, but Shino informed participants at the Namibia Oil & Gas Conference that up to 8.7 Tcf of associated gas has been found in the Orange basin by the European energy giants' continuing exploration efforts.
This quantity greatly surpasses domestic demands, potentially supporting exports like blue hydrogen and maybe liquefied natural gas, as she noted.
Following the Graff discovery in February 2022, Shell reported three more oil discoveries within its Namibian sectors.
During that same month, TotalEnergies located oil at the Venus site and is performing appraisal drilling while pursuing what might become a significant ultra-deepwater discovery.
Namcor, the state-run oil company, partnered in all these discoveries and engaged the UK consultancy Wood Mackenzie to conduct an impartial evaluation of the resources identified so far.
Shiwana Ndeunyema, Namcor’s temporary managing director, illustrated the immense scale of the discoveries thus far, equaled only by Guyana over the last decade.
“We're observing 11 billion barrels of reserves (oil in situ),” he mentioned, emphasizing, “These figures are the most cautious estimates.”
He noted that among these new findings, Venus is the largest, containing 5.1 billion barrels of crude oil in situ.
Shell's recent discovery, Jonker — an eastern expansion of the Venus play — contains roughly 2.5 billion barrels of in-place oil resource, based on WoodMac's evaluation.
According to Ndeunyema's demonstration, expedited, phased advancements are being designed for Venus and Jonker, while no developmental concepts have been suggested for Shell's other two discoveries.
Despite Graff being larger than Jonker, with roughly 2.71 billion barrels of oil in two distinct reservoirs, one holding 2.38 billion barrels and the other, a Cenomanian play, accommodating 229 million barrels.
Shell's latest discovery, Lesedi, is thought to contain about 258 million barrels of in-place oil.
