Project overview
Mosman Oil and Gas’ 100% owned acreage in the prospec ve Amadeus Basin in central Australia comprises one granted explora on permit (EP145) and one applica on (EPA155), covering a total of 1183 km2. Both tenements are in close proximity to exis ng producing oil and gas elds.
The Amadeus Basin is one of the most prospec ve onshore areas in the Northern Territory for conven onal and unconven onal oil and gas and helium. It is home to three commercial petroleum elds (operated by Central Petroleum Ltd) at Mereenie, Palm Valley and Dingo. However, despite more than thirty years of conven onal petroleum produc on history the Basin remains very underexplored by world standards.
In 2016 SRK Consul ng prepared a report for Mosman Oil and Gas into the prospec ve resources contained in permit E145 which is on trend with the exis ng producing Mereenie oil and gas eld. The report highlights the poten al for both conven onal and unconven onal oil and gas resources in proven reservoirs within two plays - the West Walker An cline and unconven onal gas resources in the Horn Valley Siltstone.
SRK Consul ng calculated unrisked P50 prospec ve resources of 12.44 Bcf conven onal recoverable gas and 1456 Bcf unconven onal recoverable gas within both the West Walker An cline and the Horn Valley Siltstone.
Geology and explora on ac vity to date
Petroleum explora on began in the Amadeus Basin in the 1950s and hydrocarbons were rst discovered in the 1960s.
The Amadeus Basin is an east-west trending sedimentary basin extending across the sourthern part of the Northern Territory and into Western Australia. The basin covers an area of approximately 207 000 km2 and contains up to 9100 m of late Proterozoic and Palaeozoic sediments. The Amadeus Basin has organically rich source rocks, reservoirs with e ec ve ver cal seals at a number of stra graphic levels and a wide variety of poten al stra graphic and structural traps. Five petroleum systems have been iden ed, at least three of which are proven. There are numerous examples of salt-related hydrocarbon plays.
Of the ve historic wells drilled within Mosman’s tenements in the 1980s, two wells (West Walker-1: 2,010m depth and Tent Hill-1: 1,387m depth) showed gas, and another (Mount Winter 1: 2,650m depth) showed minor oil.
Since acquiring the acreage in 2014, Mosman Oil & Gas has employed a methodical and cost-e ec ve explora on approach.
It undertook eld mapping and reconnaissance surveys on EP145 in 2015 and 2016, and since 2018 has been using contemporary technology and techniques to reprocess extensive seismic data from the 1980s and 1990s. Results from seismic reprocessing are promising, improving technical understanding of prospec ve plays, including salt-related structures, and con rming similari es with the nearby Mereenie oil and gas eld.
