Antelope-1 Objectives and ResultsAntelope-1 was spudded with the following objectives:Drill a structural attic ~2,269ft above the Elk-4 Lowest Gas Complete a second gas well in the Antelope block and extend the field by 2.6 miles south of Elk-4 Quantify Increases in condensate with depth Test for Shallow marine reefal limestone With the following results: Achieved - Top of reservoir within 2 metres of prognosis and the largest known vertical column in any well in PNG Achieved - Antelope-1 successful as a gas discovery well and completed as a future producer Achieved - Condensate yields range from 13 to 22 Bbl per MMcf with indications of oil in tests Achieved the well penetrated highly productive dolomite and limestone reef/platform reservoir as predicted Achieved - validated the reef porosity to be significantly higher than the previous Elk wells7
Quantify the porosity in the reef/platform facies
Results Surpass Expectations Hydrocarbons from 5,732 ftMD (1,747m) to 8,156 ftMD (2,486 m) indicate atotal column of 2,425 ft (739 m)
Antelope-1
Highly Productive Reservoir Record flows of 382 MMcfd and 5,000 BCPD and Calculated Absolute OpenFlow of over 17 BCF per day From 5,840 ftMD (1,780 m) to setting of the 7 casing, all drilling/testing operations conducted with no-returns to surface indicating significant permeability and porosity Over 500,000 Bbls of drilling fluid (mostly freshwater) lost to the formation Dolomite Zone: Net reservoir 746 ft (227 m) Av. Porosity 13% up to 30% Limestone Zone: Net reservoir 1,345 ft (410 m) Av. Porosity 7% Upper Transition Zone: Net reservoir 108 ft (33 m) Av. Porosity 5% Lower Transition Zone: Net reservoir 217 ft (66 m) Av. Porosity 4% Excellent hydrocarbon saturation characteristics confirmed by wireline logs and capillary height data
Deepened lowest known, or moved hydrocarbons in the field (from testdata) from 7,182 ftTVDss (2,189 m) in Elk-4 to 7,395 ftTVDss (2,254 m) in Antelope-1, an increase of 213 ft (65 m)8

Lowest hydrocarbons recovered 2,452 mMD
DST #14 (2,420-2,452 mMD)
DST #15 (2,462-2,486 mMD)Test mechanically unsuccessful
DST #12, #13 and #14 were successful tests that recovered gas, condensate, oil and valid pressure data in each
10
Test Update - DST #12-15 Conclusions Testing indicates gas and condensate down to 7,769 ftMD (2,368 m) / 7,133ftTVDss (2,174 m) Condensate yields at these lower intervals range from 15-22 Bbl per MMcf in field testing Condensate yields in the upper section of the dolomite were approximately 13 Bbl per MMcf in field testing PVT analysis and process simulation indicate condensate yields will be approximately45% higher through a processing plant than what is measured in the DSTs
33o-35o API oil has flowed from below 7,769 ftMD (2,368 m) / 7,133 ftTVDss(2,174 m) Due to the tight reservoir in these lower intervals, analysis indicates two possible base case outcomes i. A gas/oil contact at approximately 7,769 ftMD (2,368 m) and an oil/water contact at8,156 ftMD (2,486 m) with possible transitions between these contacts ii. A gas/water contact at approximately 8,156 ftMD (2,486 m)/ 7,520 ftTVDss (2,292 m)
These results confirm the basis for a long term well test across the deeperintervals for further oil and condensate characterization11
Antelope-1 DST SamplesThe variations observed are indicative of the oil recovered from below 7,769 ftMD (2,368 m) with 33-35 API along with a possible mixture of oil and condensate (44-49 API) and 100% condensate (52 API) DST #11 DST #12 DST #12 DST #13 DST #14

Please refer to the statement of resources in the Companys 2008 Annual Information Form filed on www.sedar.com for additional disclosure.
Contingent resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations using established technology or technology under development. There is no certainty that it will be commercially viable to produce any portion of the resources. These resource estimates are not classified as reserves primarily due to lack of marketing infrastructure, further project application, facility and reservoir design work. There is no guarantee that all or any part of the estimated resources will be recovered. Although a final project has not yet been sanctioned, pre - Front End Engineering and Design (FEED) studies are ongoing for LNG and condensate stripping operations as options for monetization of the gas and condensate.

ELK/ANTELOPE APPRAISAL STRATEGY
26
Antelope-2 Well Objectives The Antelope-2 location is located south of Antelope-1 inInterOils PPL237 Exploration Licence. The objectives of the well are: Penetrate the southern margin of the Antelope Reef and determinethe extent of the dolomite cap or higher porosity limestone reservoir predicted from seismic character and analogy to offset reef/platforms in the Gulf of Papua Investigate the lower transition zone to further quantify the nature and elevation of the fluid contacts in the southern extent of the field in particular providing more confidence in the vertical extent and commercial potential of the oil leg Through testing and the acquisition and analysis of whole cores, rotary side wall cores and wireline logs provide valuable data to further understand the resource This will satisfy the PPL237 licence commitment, potentially expand the known extent of the field an additional 2.3 miles (3.7 km) south and confirm its extension into PPL237

Elk/Antelope Appraisal StrategyFocus on Efficiency Engagement of Knowledge Reservoir to lead the effort of sub-surfacereservoir and engineering studies to progress a detailed development and depletion plan
Acquire a second drilling rig to boost drilling capacity A two rig operation will speed up appraisal drilling, allow sharing of supportservices and add significant efficiencies to reduce over all costs
Improving infrastructure and reducing reliance on helicopter transport Acquisition of additional construction equipment to establish and maintain a road network between rig operations Acquisition of transport equipment suited to jungle conditions and additional equipment for more efficient rig site preparation
Acquire additional in-field seismic to improve data coverage Fast track selection of two new well locations These will be infill locations within the Antelope structure
In summary, by combining a second rig with improvement of infrastructure and equipment, significant synergies and savings are expected to be achieved as the reliance on helicopters is reduced29

CONDENSATE STRIPPING PROJECT FEASIBILITY STUDY
30
Condensate Feasibility Study Report SummaryJuly 2009
31
Early Condensate Recovery This study was performed to evaluate the benefits of producing gas and stripping condensate prior to the start up of LNG processing
Condensate stripping is envisioned to be online 3-4 years priorto LNG start up
A majority of all the wells, pipelines, equipment and facilitiesthat will be used for the stripping operation will also be used once LNG is on line, enhancing overall economics
Liquids monetization and early cash flow are expected toprovide greater value to InterOil and our shareholders
Assuming the stripping project is sanctioned, project specificresources would be converted to reserves pursuant to the definitions in the COGE Handbook32
EDG Report Summary EDG Consulting Engineers were commissioned to evaluate the opportunity to facilitate early monetization of condensate from the Elk/Antelope field Perform feasibility study with defined product slate, a costestimate and schedule
EDG is an international company with over 25 yearsof consulting experience in the oil and gas industry
Specialized in cost-effective, innovative andcomplete solutions for upstream oil and gas applications
Specific experience in condensate projects ininternational environments33

Early Design Conclusions 400MMcfd is the best initial rate for early condensatemonetization (yielding approximately 9,000 bbls per day) We believe that the stripping facility and compression station is best located at the Purari River rather than in the Elk/Antelope field Our preferred processing case has an effective condensate recovery of approximately 9,000 bpd, which is a yield of 22.4 barrels of condensate per MMcf, based on the Elk-4 PVT analysis Oil recovery and increased condensate yield with depth would result in significantly enhanced economics35

Summary Antelope-1 has been drilled, tested and completed as one of the largest known onshore vertical wells in terms of both column height and flow capacity GLJ Petroleum Consultants has completed an independent assessment for the Elk/Antelope field and provided a certified recoverable resource estimate of 631 million BOE for the best case effective 31 December 2008 An early condensate stripping project is being evaluated and based on the current feasibility study the economics appear very robust The drilling of the Antelope-2 well along with the new seismic program and the planned long term well test at Antelope-1 will solidify the understanding of the Elk/Antelope reservoir An updated resource estimate is planned to be completed by GLJ Petroleum Consultants after the drilling of the Antelope-2 well45
Commonly Used Terms API AVO Bblsmeans API gravity or American Petroleum Institute gravity, and is a measure of the relative density of a petroleum liquid and the density of water, it is used to compare the relative densities of petroleum liquids means Amplitude Variation with Offset which is the variation in seismic reflection amplitude as a function of source-geophone distance or angle of incidence. This effect is often a hydrocarbon indicator, especially for gas reservoirs. means the Petroleum industry uses a 42-gallon barrel, which was 2 gallons larger than the barrels used by many other industries. Historically Standard Oil began manufacturing such barrels and painting them blue so that purchasers could be sure they were getting a 42-gallon barrel. "Bbl" is an abbreviation of "blue barrel". means billion cubic feet (a cubic foot x 109) means barrels of condensate per day
BCF BCPD Certified recoverable resource The estimates presented are in accordance with the definitions and guidelines in the COGE Handbook and Canadian NI 51-101 standards in relation to the estimates provided here in:-
The low estimate is considered to be a conservative estimate of the quantity that will actually be recovered. It is likely that the actual remaining quantities recovered will exceed the low estimate. If probabilistic methods are used, there should be at least a 90 percent probability (P90) that the quantities actually recovered will equal or exceed the low estimate. The best estimate is considered to be the best estimate of the quantity that will actually be recovered. It is equally likely that the actual remaining quantities recovered will be greater or less than the best estimate. If probabilistic methods are used, there should be at least a 50 percent probability (P50) that the quantities actually recovered will equal or exceed the best estimate. The high estimate is considered to be an optimistic estimate of the quantity that will actually be recovered. It is unlikely that the actual remaining quantities recovered will exceed the high estimate. If probabilistic methods are used, there should be at least a 10 percent probability (P10) that the quantities actually recovered will equal or exceed the high estimate. Marketable gas estimates exclude CO2, shrinkage and gas used for fuel.
DST ftMD ftTVDss Inversion
means Drill Stem Test means a measured depth in feet in the well from the drilling rig datum used to discuss depth within a single well means a depth in feet corrected for well geometry to a true vertical depth from a sea level datum used to compare between wells means a process of deriving from observed field data a subsurface model that is consistent with that data (Sheriff, 2002). Seismic inversion is the process of quantitatively transforming seismic reflection data into a rock property description of a reservoir, achieved via the integration of surface seismic data, well logs, vertical seismic profiles, and geological knowledge. LNG means Liquefied Natural Gas MMcf/MMcfd means a measure of gas volume in Millions of cubic feet or a rate of gas flow in Millions of cubic feet per day PPL means Petroleum Prospecting Licence as defined in the PNG Oil and Gas Act PVT Analysis means a series of detailed analyses of a hydrocarbon sample conducted under different conditions of volume and temperature Tcf means trillion cubic feet (a cubic foot x 1012) WAVSP means Walk Away Vertical Seismic Profile in which seismic data is recorded in the subsurface in a well, using energy sources arranged in everincreasing linear offsets from the well on the surface, and provides the most robust tie of time, depth and seismic character to the well.
