History
A float as Orion Petroleum, it drilled dry holes, merged into Petrel, then Warrego, found gas at West Erregulla and was bought by Hancock for $0.36 a share in 2023.
2007-2011: Orion's dry holes and boardroom fights
The company began as Orion Petroleum, a New South Wales oil and gas explorer admitted to the ASX on 10 December 2007 after issuing 115.5 million shares at $0.20. Its first wells disappointed. Willaroo-1 found oil shows in poor sands but recovered only 2-4 barrels and was abandoned in May 2008. Nyngynderry-1, a frontier Darling Basin test, reached 2,266 m with no hydrocarbons that October. Toenda-1 was also dry in 2010. In August 2008 Orion farmed out its coal seam gas rights to Eastern Star Gas, which funded coreholes to earn up to 75% of PEL 6 gas.
In October 2009 the chairman and managing director resigned over a dispute with major shareholders about merger deals. A binding merger with Gas2Grid was signed in November 2009 but was terminated in March 2010 after the independent expert said it would revise its opinion. Octanex then bid for Orion, but the bid lapsed in June 2010 with acceptances under 1%. In 2011 the board changed again: Managing Director Russell Langusch left in March, and in June Eastern Star Gas won board control and began a strategic review.
2011-2013: Petrel, Texas and Uruguay
The review ended in a deal to buy unlisted Petrel Energy for 115.1 million new shares, which closed in January 2012 and left Petrel holders with about 43%. Petrel brought a Barnett Shale gas venture in Texas, whose first well came on at about 570,000 cubic feet a day in May 2012. The New South Wales licences were put up for sale and six of seven were sold for $1.05 million.
Petrel then turned abroad. In late 2012 it bought 25% of Schuepbach Energy International (SEI), which held Uruguayan shale concessions and two Spanish gas licences. In 2013 it bought a 40% share of Alberta Cardium tight oil, funded by a $10.65 million raising at 8.5c, and the Lochend well gave 150 barrels a day. In December 2013 it lifted SEI to 51% and raised $3 million at 13.5c. Shares on issue rose from 234 million at the end of 2012 to 431 million at the end of 2013.
2014-2017: Uruguay drilling and mounting dilution
Uruguayan coring in 2013-14 confirmed oil-generating shale, and seismic completed in October 2014 supported a certification of up to 902 million barrels of prospective resource in January 2015, later restated with gas included. A Spanish resource was cut to 992 BCF net. Petrel tried to sell the Cardium assets, sold the Texas project by January 2016, and sought a Uruguay partner without finding one.
Funding came at ever lower prices: 11.5c in October 2014, 4.5c in July 2015, 2c in February 2016, then a 1c rights issue completed at about $5.25 million in 2016. By 2016 shares on issue had passed a billion, reaching 1.67 billion in 2017. Cerro Padilla-1, drilled in 2017, found only 2 m of oil sand, which the company called modest and the CEO said was not material. Cerro de Chaga-1 ran into difficult drilling. A further raising at 1.1c brought in $5.45 million in total.
2018-2019: Collapse and the Warrego takeover
By February 2018 cash was $831,000 and ASX queried the company. The Uruguay and Spain assets were written down, giving a half-year loss of $19.97 million. A rights issue at 0.4c raised only $247,451 of up to $4.5 million sought. Petrel swapped interests to lift Spain to 97.5% and cut Uruguay to 49%, later 41%, and raised small sums at 0.21c. The year to June 2018 showed a $29.1 million loss, with net assets of $3.5 million. Shares on issue reached 2.4 billion at the end of 2018.
In November 2018 Petrel agreed to buy private UK company Warrego in a reverse takeover. Warrego held 50% of EP469 (West Erregulla) in Western Australia, with Strike Energy funding the first A$11 million of a well. The deal closed in March 2019, and Petrel was renamed Warrego Energy. The end-2019 share count of 708 million is consistent with the reshaped company, though the beats do not detail the change.
2019-2021: West Erregulla delivers
West Erregulla-2 found gas in three layers in 2019, with the main Kingia sandstone showing 58 m of net pay. A flow test reached 69 MMscf/d in October, and Strike booked 1,185 BCF of contingent resource. Warrego raised $6.61 million at 9.5c and $12 million at 29c.
A 2020 independent review certified a lower figure, 513 Bscf gross, and Strike publicly disagreed. Warrego rejected an all-scrip proposal from Strike in March 2020, raised $15 million at 13c and $32 million at 21c, and in September signed a binding 155 PJ gas sale to Alcoa starting 2024. An ASX suspension followed a missed cleansing notice. WE-3 lost its drilling assembly and was later suspended in an over-pressured zone, while WE-4 found the thickest Kingia in the basin. In June 2021 Warrego raised $50 million at 22c, and in July Strike bought 8.16% of Warrego. WE-5 flowed poorly. In October 2021, 2P reserves were certified at 300 PJ gross. Warrego also bought 50.1% of El Romeral in Spain in 2021 and agreed in December to farm out half of STP-EPA-0127 to Mitsui.
2022-2023: A bidding war and delisting
Warrego kept its Spanish assets in March 2022, while first gas slipped to late 2024. WE-3 was re-entered and confirmed the field extended north, lifting 2P reserves 41% to 422 PJ gross. It flowed 83 mmscfd in August.
In November 2022 Strike proposed a scrip merger, and Warrego signed with Beach Energy at $0.20 cash. Hancock then bid $0.23, Beach countered with $0.25, Hancock moved to $0.28, and Beach declined to match on 9 December. Strike launched a rival scrip bid. Hancock declared its offer unconditional, then lifted it to $0.36 once it reached 40% acceptances. It held over 50% by February 2023, put three nominees on the board with Ian Plimer as chairman, and Strike accepted the cash offer for its holding. The offer closed on 24 February with 95.63%, and Hancock compulsorily acquired the rest. Warrego was removed from the ASX on 9 March 2023, with holders paid $0.36 a share. Cash at the end of 2022 was $19.899 million with no debt.
