2 Flax Field Major Growth Potential Multiple large proven oil discoveries (Flax and Juniper) 100% owned and operated by Acer Energy. Flax field already on production (with the benefit of >$50M infrastructure footprint). Flax field historical production performance impacted by suboptimal well completions. Multiple new target reservoirs identified above the current producing zones (potential for material reserves increase). Successful well re-entry and test of the first of these zones. Results from 3D seismic and engineering review indicates upside potential around optimum new well locations and modern fit for purpose well completions and work overs. 34 Bcf (P50 OGIP) of liquids rich gas quantified for the 1 st time. Small scale LNG opportunity being pursued to provide path to market for gas from both Flax and surrounding discoveries. Active work program commencing in Q

4 Oil Type & Pricing Comparison Both Flax and Juniper oil are very light at 54 & 52 API gravity respectively. Higher API petroleum is less dense (or lighter) and generally the higher the API the higher the value (requires less refining). Flax oil is sold based on Tapis pricing. API Gravity Liquid Relative Density >55 Condensate Lightest ~54 Flax Field ~52 Juniper Field >38 Light Crude Oil Medium Crude Oil Heavy Crude Oil 10 Water 0-10 Extra Heavy Crude (Tar sands/bitumen) Heaviest 4

5 Flax Field Recent Activities 1. Geological and Geophysical (G&G) activities: Acquired, processed and interpreted 141 km 2 of new 3D seismic (Flax and Juniper). 2D seismic reprocessing. 2D & 3D seismic inversion. Full petrophysics review of all wells. 2. Tight Reservoir Evaluation Study (Schlumberger): Phase 1 - Review of all production, G&G and engineering data (logs, cores, etc), forensic review of the Flax field development and well completions. Phase 2 - MEM model, Flax field analogues, new modern fracture stimulation design. Peer review undertaken by Tight Reservoir Centre in Denver. 3. Successful intervention on the Flax 5 well to confirm suitability for artificial lift trial. 4. Successful well re-entry and test of a Mid Patchawarra channel sand in the Flax 1 well. 5

6 Flax Field G&G Results The Tirrawarra and Patchawarra intervals are mapped with increased confidence. The crestal area between Flax 1 and Flax 2 offers an attractive infill well location. As independent structures Flax and Juniper appear connected on 3D seismic at a depth similar to Flax 5. Increased section thickness between Flax and Juniper appears prospective for reservoir Integration of all well/log data and consistent petrophysics analysis has increased the confidence that productive reservoir potential exists from the Mid/Upper Patchawarra sands. Inversion of seismic data has provided additional clarity in mapping reservoir units. Inversion attributes are proving to have good correlation with gross reservoir in wells. Jurassic Birkhead channel sands are a secondary target for new Flax and Juniper wells. Seismic amplitude Acoustic impedance 6

8 Flax Field New Reservoir New productive reservoir with encouraging oil/gas ratios. The same and similar reservoirs appear in other wells. Reservoirs can be tested without drilling new wells. New reservoirs are in addition to the existing resource estimates. New Reservoirs Yet to be Tested 0.572km New Productive Reservoir Current Productive Reservoirs 15 mmbbls P50 OOIP and 34 Bcf P50 OGIP 0.94km 8

9 Flax Field Productive Reservoirs The Flax field is a solution gas drive reservoir and relies on the natural gas drive in the reservoir to lift crude oil from a depth of 2,800 metres to surface. Hence the Flax field also contains significant amounts of wet gas, with RISC estimating the P50 OGIP estimate to be ~34 Bcf across the Tirrawarra and Basal Patchawarra reservoirs which is in addition to their P50 oil resource estimate of 15 mmbbls OOIP from the same reservoirs. Recent successful testing of a mid-patchawarra sand in Flax 1 indicates potential exists for a material increase in both the oil and gas resource estimates across the Flax field. Further value enhancement is possible from the Flax field if a market can be secured for the liquids rich gas currently flared as a bi-product of existing oil production. The company is currently reviewing a number of options with respect to gas off take opportunities from the Flax field including the feasibility of establishing a small scale LNG hub in the permit area.

11 Flax Field New Approach The Flax well locations were chosen based on an EOR development plan rather than seismic based locations. With the benefit of the existing wells and new 3D seismic, upside exists to locate future wells in optimum locations. Lower strength proppant was used in all wells except Flax 1 (premium grade proppant). Notably Flax 1 has produced >50% of total field production to date. A number of well completion issues were encountered during initial development. Several identified remedial activities have the potential to significantly improve well production performance without the need to drill new wells. Previous Stimulations New Stimulations Proppant 50, ,000 lbs 150, ,000 lbs Flow rate 14 bbl/min 30 bbl/min Fracture half length ~100 metres ~350 metres 11

12 Flax Field Artificial Lift Trial The Eastern flank of the Flax structure looks to have improved reservoir quality in the Patchawarra formation. These conditions support trialling artificial lift (pumping) to assist well production and test the improved field production capability. Artificial lift is planned to be trialled on Flax 5 where in flow to the well bore is between bbls/day (under reservoir drive) however due to reduced bottom hole pressures production has declined. If proven successful, artificial lift may well apply to other wells (equipment is re-useable). 12

13 Small Scale LNG Opportunity Provides a potential path to market for gas currently produced from the Flax oil field as well as surrounding discoveries/prospects (Juniper, Yarrow, Crocus, Ginko, Tallow, Cyprus). Introduces multiple new sources of revenue LNG sales, Ethane, Propane, Butane. Ability to leverage existing sunk capital and operational footprint. The Acer Energy team has a successful track record of vertically integrating upstream gas resources with downstream infrastructure. 13

14 Small Scale LNG Business Build Flax Field (PRL 14) Flax Field LNG Plant Market LNG Flare Gas LPG Optimised Flax Oil Production Increased production from New Patchawarra Reservoirs Additional Gas Sources 1. Juniper (PRL 17 & 18) 2. Yarrow Field (PRL 17) 3. PEL 103 (Tallow & Cyprus) 4. PEL 101 (Crocus & Ginko) Liquids Optimised Production Oil/Condensate (bbls) 14

15 Acer Energy LNG Why the Opportunity Exists Major increase in oil/diesel prices (Aust. is a large importer of diesel with growing demand). Significant advancements in small scale LNG technology including cost (modular design). Multiple small scale LNG plants built in Australia have proven the technology and reliability. Ability to leverage sunk capital as well as the existing operational footprint (i.e. Flax field facility infrastructure, operational personnel/capability and multiple sources of gas supply). Flax field gas is very rich in heavy hydrocarbons thereby introducing additional liquids based revenue streams (ethane, LPG s). The Flax field is unique in that it is the only existing operation of its type in the Cooper Basin outside of the Santos operated fields. Diesel consumption alone in the Cooper Basin is estimated to be >200 million litres p.a. Imposition of carbon scheme could assist market off take opportunities (gas produces ~27% less CO2 emissions than diesel on an energy equivalent basis). 15

16 Acer Energy LNG - Major Geographic Advantage Unique location allows access to QLD/NSW/Victoria/SA markets. Market study has identified sufficient regional customers necessary to underwrite the initial development. Flax field is located in South Australia (SA) midway between Moomba and Ballera (excellent for rotation of field staff and access to services). SA regulatory environment is extremely functional and pro development. Being adjacent to the QLD border enables access to government maintained bitumen roads. Flax field is situated on the Innamincka Dome which is structurally a high point in the Cooper Basin. The Flax field had the least operational interruption of all producers following the regional flooding in 2010/2011. The Flax field also has two separate entry and exit roads. Flax field is extremely well located relative to the wet gas resources of the Northern Patchawarra Trough which has historically indicated higher liquids and lower CO 2 levels. Significant expansion potential exists with the foundation infrastructure representing the only other alternative path to market for gas in over four decades of operations in the Basin. 16

17 Flax Field Next Steps Undertake modern stimulation across the Tirrawarra / Basal Patchawarra sands in Flax 2. Test the productive capability of the new upper Patchawarra reservoirs identified in Flax 2. Recomplete Flax 1 across the full 9 metres of the newly proven mid Patchawarra pay interval and undertake a new modern fracture stimulation. Recomplete Flax 3 to access the same mid-patchawarra reservoir identified in Flax 1. Test the productive capability of the new upper Patchawarra reservoir identified in Flax 3. Install Artificial Lift on Flax 5 and test the improved well production capability. Make final decision as to best location for a new Flax field development well. Confirm gas reserves and commence approval process for proposed LNG facility. 17
