WHO IS DISCOVERY ENERGY Publicly reporting oil and gas Company based in Houston with operations in the Cooper Basin, South Australia Our primary asset is a Petroleum Exploration Licence (PEL) which was acquired in 2012 PEL 512 is located in the Western Oil Flank of the Cooper Basin and consists of more than 584,000 acres Over US$10 million invested so far in developing PEL 512 More than US$10 million budgeted for exploration activities in 2017-18 PEL 512 Project (Western Oil Flank) 584,651 Acres

WHAT WE FOUND IN AUSTRALIA Stable Socio-economic platform Clear and transparent regulations and government British-based contract legal system Stable or hedge able currency Free trade policies Established oil and gas markets and Infrastructure Extensive online oil and gas databases Exploration rights available directly from government High Net Revenue Interest economics Keith I am trying to convey the vastness, but also have the bullet points… any ideas?

WHY THE COOPER & EROMANGA BASINS Located in Queensland/South Australia Cooper Basin covers approximately 32 million acres and developed in the late Carboniferous/early Permian Maximum thickness of sediments – ~2,750 meters (9,000 feet) Eromanga Basin covers approximately 250 million acres overlaying the Cooper Basin It developed as an interior sag over central & eastern Australia First gas discovered – 1963 First oil discovered – 1970

WHY WE LIKE SOUTH AUSTRALIA South Australia is pro-development and works with industry participants to constructively manage its oil and gas resources Data sharing of all seismic, well and technical data, in an easy-to-access via public website Cooperation among neighbors - companies share and collaborate Exploration similarities to that in West Texas during the 1960’s, but with modern geo-science tools Keith, Do we have a good photo or graphic to fit on the right of this slide?

WHAT HAS THE COOPER BASIN PRODUCED Australia’s largest and most mature conventional onshore hydrocarbon basin with 50+ years of production history More than 3,400 wells drilled; average depth of just 1,350 metres (4,400 feet) High quality reservoirs, some with stacked pays, produce high well flow rates Produced in excess of 180 Mmbbls of oil, 81 Mmboe of condensate Produced 6.9 Tcf of natural gas and 79 Mmboe of natural gas liquids Source: DMITRE PEPS Database 7

WHAT IS THE STATE OF COOPER INFRASTRUCTURE Regional Transmission Oil and gas is transported to a central processing center located at Moomba by either tank wagon trucking or gathering pipelines Gathering system expending to facilitate increased production Recent addition of an 18” trunk line to the Moomba Plant with capacity of >20,000 Bopd Oil and liquids piped from Moomba to Brisbane or Port Bonython for export to world markets Moomba Terminal Pipeline to Port Bonython Pipeline to Brisbane PEL 512 Licence Oil Pipelines Gas Pipelines To Gladstone To Mt. Isa To Sydney To Adelaide Cooper Basin To Brisbane Lycium Hub New 18” Trunk Line Ballera Gas Plant Eromanga Basin Moomba Gas Plant Source: DMITRI, Beach Energy, Santos

WHAT ARE THE COOPER BASIN ECONOMICS Shallow low-cost conventional wells at ~US$1.8M Rapid cash flows, quick drill and tie-in periods range from 45 to 90 days from discovery to revenue Typical economic threshold for a well is 65,000 Bbls (200 Bopd) of initial annual production assuming a post-drill price of US$50/Bbl Butlers-1 Well on PEL 92 – drilled in 2009 and had an Initial Flow Rate of 2600 Bopd and reported to have 2.1 Mmbo proved and probable reserves Recent operating costs reported by nearby operator at US$20 per barrel Net backs based on US$50 Brent pricing calculates to US$30 per barrel

HOW DO WE VIEW AUSTRALIAN INVESTMENT Australian offers attractive opportunity for investment for conventional oil and gas exploration and development Broad oil and gas resource base with established exploration, processing, transportation, service and market industries Cooperative government, industry and local community stakeholders Cooper Basin’s Western Flank where Discovery is currently focused, provides shallow, low-cost, highly successful exploration experience Profitability has been sustained during the recent dramatic downturn in oil prices
