OPERATIONS REVIEW

INDIA CAMBAY FIELD, GUJARAT (OILEX OPERATOR - 45%) The purpose of the 2008 Cambay Field drilling program comprising 6 consecutive appraisal /development wells is to gather detailed lithological and reservoir fluid information in the Cambay Field. In combination with the high quality 3D seismic survey over the block and the extensively reworked data from over 60 old wells, Oilex anticipates that the information from the new wells will provide a comprehensive basis for certification of oil and gas reserves at the level of the Oligocene and the Eocene main potential reservoir units and any of the exploration targets that may prove to contain hydrocarbons. The first two wells in the program have been concluded and the third well is drilling ahead. Cambay 23Z, the first in the sequence spudded on 07 March 2008 and was suspended as an intended future gas well. The second well, Cambay-19Z is an oil discovery at the level of the Basal EP IV sandstone. A further interval of 12 metres with similar log response will be tested with a workover rig at the earliest opportunity. The results to date are very encouraging for the broader potential of the deeper zones. The resources for the two main intervals Oligocene OS II and Eocene EP IV have been estimated from the existing data base of wells and 3D seismic and presented in the table below. These estimates do not include oil or gas that may be found in both shallower and deeper potential reservoirs that will be intersected during the drilling program.

# Includes approximately 52 BCF of gas produced to date. mmstb – million stock tank barrels

Gross resource estimates (100% basis) calculated in 2007 using the 3D seismic data set and the existing well data base. Oilex net interest in Cambay PSC is 45%. All 6 appraisal wells will test the Oligocene and Eocene primary targets and any of those wells that indicate production potential from these zones may be suspended for future production of oil or gas. The wells are located to provide at least one modern data point in each geological compartment recognised from the 3D seismic data and the existing well data. Four of the wells will also test deeper exploration targets at the base of the Eocene section and fractured Deccan basalts that have proven to be oil reservoirs in the Tarapur block operated by GSPC immediately to the north and on trend with the Cambay Field. The database that already exists is comprehensive with over 60 wells drilled on the block and the reservoir distribution at OS II and to a lesser extent EP IV, has been mapped with a relatively high degree of confidence. New prospects at OS II and EP IV particularly in the northern part of the block and at stratigraphic horizons other than OS II and EP IV including Basal EP IV, are now being developed with the benefit of the newly acquired well data.

Cambay-19Z Oil Discovery Cambay-19Z, the second well in the appraisal program is an oil discovery in the Basal EP IV reservoir. The well spudded on 25 May and was released after completing the first of a series of planned tests on 09 July 2008. The well has proven the productive potential of deeper zones on the Western High Block. These zones were interpreted to be prospective exploration targets and by comparison with at least 3 older wells that were drilled in the period 1960-1990, there are probable oil zones that were missed in the initial evaluation. There is, therefore, a good possibility that the Basal EP IV oil bearing sandstone is present over most of the Western High Block. The volume of oil for the deeper Eocene (including Basal

EP IV) and fractured Deccan basement objectives was previously estimated at about 60 million barrels oil in place. Cambay-23Z and Cambay -19Z Well Bore Schematic Summary

The Western High Block is most prospective for oil and the Basin Area most prospective for gas. The areas are separated by a major fault that trends approximately north-south controlling the general hydrocarbon distribution. This is illustrated in the diagram of the well bore trajectory for Cambay-73 that is anticipated to intersect gas in the upper objectives and oil in the lower objectives.

Cambay-73 Well Bore Trajectory on 3D Seismic line showing main target zones The gas that has been produced in the past has come from the OS II in wells that are located mainly in the southern central part of the block. No gas has been produced from the EP IV in the past.

Locations by colour code for initial 6 wells at 3 main stratigraphic horizons

Cambay-23Z appraisal well

Objectives: Primary: Eocene EP IV - gas Secondary: Oligocene OS II – gas Cambay-23 was drilled in 1963 and is reported to have tested gas from the EP IV zone at rates of 14,500 cubic metres per day through a 5mm choke. The appraisal well Cambay-23Z was designed to intersect the primary target about 200 metres from the same zone in the initial well in the area of a strong amplitude anomaly

Status: Spud date: 07 March 2008 Rig Release Date: 26 April 2008 Total Depth: 2,100 metres in Cambay Shale Formation Well Status: Suspended gas well with gas shows in OS II and EP IV.

Operations: Cambay-23Z was drilled as a deviated well in a northeasterly direction from the original well pad. Cores were cut in the EP IV with the aim of providing information that would be beneficial in designing a fracture stimulation of low permeability formation. A fracture stimulation will be designed and implemented when the last of the core data are received.

Results: Good gas shows were recorded while drilling the Miocene and Oligocene secondary objectives in this well. The evaluation of the wireline logs over the Basal Miocene and Oligocene OS II intersected at 1,505 metres and 1,545 metres respectively indicates the presence of about 9 metres of gas-bearing pay in these sandstones that are of good reservoir quality, each with about 25% average porosity. Cores were cut in the EP IV and wireline logs were run over the Eocene section. Indications from logs are that the EP IV is gas-bearing and a cased-hole DST will be conducted over the interval 1,961m – 2,005m when core results become available and a fracture stimulation program is formalised. Cambay-23Z well has been completed as a potential gas production well

Status: Spud date: 14 May 2008 Rig Release Date: 09 July 2008 Total Depth: 2,350 metres in Deccan Trap basement Well Status: Suspended oil and gas discovery awaiting further testing of Basal EP IV oil zone and EP III and EP IV zones that were drilled with good gas shows. A cost effective workover rig has been contracted to undertake the further testing. The drilling rig has demobilized from C-19Z to Cambay-73 location.

Operations: DST #2 will be carried out over an interval of 16 metres of potential oil pay below the zone that was tested by DST #1. DST #3 will be conducted over an interval of about 23 metres at the EP III and EP IV where good gas shows were recorded while drilling and the zone is expected to flow oil by analogy with other wells on the Western High Block of Cambay Field. DST #4 will be conducted at the shallower level of the OS II reservoir unit depending on the results of the DST’s at the deeper levels. Strong gas shows were recorded at the OS II level while drilling. In the event that the well is retained as an oil producer, the OS II will not be tested in this well.

Results: DST #1 successfully flowed oil to surface at a rate of over 800 barrels of oil per day (BOPD) for the first hour of the test and later stabilised at a rate of 120 BOPD on 1” choke during the final phase of the 32 hour flow period. No formation water has been produced with the oil which is 410 - 430 API gravity. The Basal EP IV zone is present in at least three old wells on the Western High Block. These old wells were either not tested or were poorly evaluated and appear to have a similar log response to the zone that was successfully tested in Cambay-19Z. Preliminary indications from seismic and the analogous well logs are that the Basal EP IV may extend across the Western High Block.

For each of the 6 wells in the Cambay program, it is generally intended to demobilise the rig from each location as soon as drilling and logging operations are completed. Further tests on each well will be conducted with a wireline unit that has the capability to undertake the full range of activities that may be required to test the wells conclusively at a much lesser day rate..

Approval Received for Additional Well Locations The Ministry of Environment and Forests (MOEF), Government of India, gave its formal approval in May to the proposal by the Cambay Joint Venture to drill up to 60 additional development wells within the Cambay block in the event that re-development of the Cambay Field is warranted by the current 6 well appraisal drilling program. With the flexibility to construct new drilling sites, the opportunity now exists to test other prospects at different stratigraphic levels in other areas of the block that have high potential for gas and oil discoveries.

SABARMATI FIELD, GUJARAT (OILEX OPERATOR - 40%) No further work has been carried out in the past quarter. Intermittent production of oil continues from Sabarmati-1.

BHANDUT FIELD, GUJARAT (OILEX OPERATOR - 40%) No further work has been carried out in the past quarter. Oil continues to be produced intermittently from existing wells.

INDONESIA WEST KAMPAR PSC, CENTRAL SUMATRA (OILEX - 45%) The resource estimate for Pendalian Field has been upgraded to 13.7 million barrels oil in place, with 1,800-2,000 bopd production anticipated in Q4 2008. A Plan of Development (POD) including an updated resource assessment for the Pendalian Oil Field (Oilex 45%) located in the West Kampar Production Sharing Contract (“PSC”) area in Indonesia (Fig. 1) is being submitted to the Indonesian Government for approval. The POD is based on a Best Estimate Contingent Resource of 13.7 million barrels oil in place (mmstboip) (Table 1). The represents an increase of 14% on the resource announced previously which was based on a single oil reservoir. The objective of the POD is to bring Pendalian Field into production in 2 phases comprising 2 wells in phase 1 and full field development of 3-4 wells in phase 2. The previous plan was to start production at a likely rate of about 1,200 barrels of oil per day (“bopd”) from a single well, Pendalian-3. The first phase has now been expanded to include a second well, Pendalian-4 with a corresponding increase in the likely production rate to 1,800 – 2,000 bopd anticipated in Q4 2008.

Contingent Resource Oil in Place (100% basis) – Pendalian Field As required in Indonesia, the technical studies are carried out by an independent third party appointed by the regulator (BPMigas) with input and review by personnel from the operator, PT Sumatera Persada Energi (SPE), and BPMigas. Oilex has also been participating in this process. The development plan is based on results from the Pendalian-1 well drilled in 1993 and the Pendalian-3 appraisal well which was drilled, tested and suspended as a future oil production well in November 2007. Pendalian-3, funded by Oilex as part of the farmin arrangement with SPE, flowed oil at potentially commercial rates from two shallow zones in the Sihapas Sandstone. The commingled flow potential with artificial lift was estimated to be up to 1,200 barrels per day. To date, significant conclusions arising from this independent evaluation are:

• Inversion studies of the seismic data indicate that the Sihapas sands are continuous reservoirs, supporting the volumetric assumptions for the Pendalian Field.

• The Best Estimate Contingent Resource of oil-in-place determined by the independent third party for the two Sihapas zones is 13.7 mmstboip (gross), with a High Estimate volume of 29 mmstboip (gross). These volumes are similar to those determined by both SPE and Oilex.

• A staged approach to the development, with initial production from the Pendalian-3 well followed by Pendalian-4 production well, 3D seismic and full field development was recommended, subject to approval by the Indonesian Ministry of Petroleum.

The recommended development schedule, subject to regulatory approval, calls for both Pendalian-3 and Pendalian-4 to be onstream in Q4 2008. Plans are in place for the early drilling of the Pendalian-4 well and tenders have been received for conducting both 2D and 3D seismic programs in the West Kampar block in 2008. Ongoing mapping has confirmed the exploration potential of the West Kampar PSC which will be delineated by additional seismic coverage and investigated with the drilling of 3 exploration wells in a campaign scheduled to commence later this year.

OMAN BLOCK 56, SOUTH OMAN (OILEX OPERATOR – 25%) Drilling operations commenced in Oman at the end of 2007 and 3 wells were drilled in the first phase, 2 of which were oil discoveries. The rig was released for a period after the third well to enable results to be evaluated before the second phase of 4 wells, which is anticipated to commence in August 2008. The results of the Phase 1 drilling program in Block 56, Oman have been very encouraging with the Sarha-1 well likely to be a commercial discovery. Prospects selected for the 3 well program were based on the interpretation of existing seismic data and provided a balance of exploration targets ranging from moderate (Sarha-1, Ghadaq-1) to high risk (Alyanbou-1). The Sarha-1 discovery well confirmed that the productive trend in the adjacent block continues into Block 56. New seismic acquisition and reprocessing of existing data indicates that there is a number of structures similar to Sarha-1 present in the western flank area of Block 56 and the most prospective of these will be the locations for several of the wells in the Phase 2 drilling campaign. It is anticipated that further drilling will be carried out on the Sarha discovery to evaluate the potential of oil zones not able to be tested in Sarha-1 and to provide information required for development of the Al Khlata oil pool discovery. Preliminary estimates of the discovered petroleum initially in place based on the current data range from 20 to 70 million barrels (on a 100% basis). Given the characteristics of the oil recovered at Sarha-1 there will also be a focus on establishing the recoverable reserves volume and specialists in this type of development are studying the data from Sarha-1 to estimate the recoverable volumes and to provide input to a development plan. Heavy oil (preliminary oil gravity of 13.30 API) was recovered during testing of the Al Khlata zone in the Ghadaq-1 well and these results will also be the focus of review given that oil with these characteristics is routinely produced in Oman and in other heavy oil areas. The results from Alyanbou-1 which was a higher risk test of a large anticlinal structure in a remote area of the block will be incorporated into the overall prospectivity assessment.

Background The South Oman Salt Basin is a prolific oil producing province with extensive pipeline infrastructure linking the producing fields to the refining and export facilities in the north of the country. The oil produced from these fields is characteristically heavier with density in the range 150 - 280 API gravity. All of the 7 reservoir objectives drilled in the first 2 wells appear to be oil-bearing and preliminary studies on the feasibility of producing the heavy oil are now in progress.

Location of pipeline infrastructure and fields South Oman Salt Basin. Location and Infrastructure Map Several of the fields in this area hold over 1 billion barrels of oil in place. Most of these fields were discovered by PDO during the last 20 years. The most recent large field development to take place in the region is Oxy’s Mukhaizna Field which is reported to be over 2 billion barrels of oil in place and which will be produced by steam flood to improve the flow characteristics of the 150 API gravity oil. The Sarha and Ghadaq prospects, like many others in the western part of the block, are similar in structural form and reservoir objectives to the nearby producing fields operated by PDO. The pipeline network from those producing fields in the main part of the South Oman Salt Basin is only about 30 km to the west from Sarha-1.

Comment: The well was classed as a frontier exploration well. It was located in the northeastern sector of the block about 60 km from the nearest well control, to the east of the major structural lineament in the Tertiary Basin where no wells had previously been drilled.

Seismic Acquisition Preparations for tender of the 3D seismic acquisition program have been completed. Acquisition is expected to start in Q4.

JOINT PETROLEUM DEVELOPMENT AREA BETWEEN TIMOR LESTE AND AUSTRALIA JPDA 06-103, FLAMINGO BASIN OFFSHORE JOINT PETROLEUM DEVELOPMENT AREA (OILEX OPERATOR – 25%) The first phase of offshore operations has commenced in the Block JPDA 06–103, located in the Timor Sea JPDA between Timor-Leste and Australia. The Geowave Champion seismic vessel has completed its clearances and is acquiring the extensive, high resolution Maura 3D marine seismic program over an area of 2,082 km2. Data from this survey will be combined with existing 3D seismic surveys to provide 3D seismic coverage over more than 90% of the area of the Block. Processing of the data is expected to be concluded about the end of 2008 and the interpretation of the data over the entire block is anticipated to be completed by about end of March 2009. Locations for exploration wells will then be selected for drilling starting about mid-year 2009. To that end, on 13 June 2008 Oilex issued a conditional Notice of Award jointly with Nexus to Sedco Forex International for the supply of the Transocean Legend semi submersible drilling rig. The rig would drill development wells for Nexus before 2 wells for Oilex, estimated to start in about mid-year 2009. Oilex has accordingly made application, on behalf of the JPDA Block 06-103 Joint Venture, seeking an extension of time under the PSC to enable its 2 wells to be drilled by January 2010 rather than by January 2009. The application is under review by the relevant governmental authorities. New Discovery – In April of this year, a significant oil discovery at Kitan-1 and -2 was made by ENI, the operator of block JPDA 06-105 (adjacent to the west of JPDA 06-103). The Kitan-1 discovery well flowed oil at a rate of 6,100 BOPD from a drillstem test. The discovery was followed by an appraisal well at Kitan-2 that confirmed the commercial viability. These wells lie close to the JPDA 06-103 block boundary and confirm the oil potential of the basin. ENI subsequently made a Declaration of Commercial Discovery and the Timor Sea Designated Authority based in Dili, Timor-Leste declared Kitan a Development Area in May.
