ASX/Media Release August 26, 2008
30 June 2008
Proved, Probable & Possible Reserves
____________________________________________________________
Grand Gulf Energy Limited [ASX Code: GGE] is pleased to report that its net reserve position which includes for the first time initial Proved, Probable and Possible Reserves for the Napoleonville Salt Dome project, as of 30 June 2008, is 10..5 Bcf gas and 178,000 Bbls oil. This is detailed in the table following.
Grand Gulf 3P Net Reserves |
Category | Gas (MMcf) | Oil (MBbl) |
Proved | 4,315.9 | 35.3 |
Probable | 847.6 | 99.8 |
Possible | 5,338.0 | 43.4 |
Total 1P+2P+3P | 10,501.5 | 178.5 |
Mr James Trimble, Grand Gulf?s Managing Director said ?On the basis of $110/Bbl oil and US$8/Mcf gas prices Grand Gulf?s Future Net Revenue from Proved and Probable reserves alone, discounted at 10%, is over US$16 million?.
?If the Possible reserves are added the value is over US$28 million. This is 4 times Grand Gulf?s market capitalisation.? Mr Trimble said.
The distribution of Grand Gulf?s reserves is very much related to the status of the areas in which it operates. Most of its Proved reserves are in Oklahoma where it has been drilling for some time. All of its Possible reserves are in the Napoleonville Salt Dome project. The reserves at Napoleonville are based on an initial 4 Proved Undeveloped locations, 1 Probable location and 3 Possible locations from a total of 20 prospects at this date, including the first five wells scheduled to be drilled.
There are many more leads and prospects that will be added to reserves reports in the future as wells are drilled, the fault blocks are better defined and production is established, which under the guidelines for reserve definition will allow wells to be moved from one category to another, and new wells to be added. Many of the larger prospects defined at Napoleonville are not classifiable as reserves at this point.
The distribution of Grand Gulf?s reserves over its areas of activity is detailed in the following table:
| 3P Net Reserves |
Area | Gas (MMcf) | Oil (MBbl) |
Oklahoma | 3,525.8 | 12.5 |
Napoleonville | 6,745.2 | 62.1 |
ConocoPhillips #4 | 26.4 | 0.4 |
Texas | 204.1 | 103.5 |
Total Reserves | 10,501.5 | 178.5 |
Oklahoma
Grand Gulf?s reserve position continues to grow in Oklahoma. Drilling in 2008 will continue to move more reserves into the PDP category and will also confirm the benefits of 3D seismic in its leases.
93% of Grand Gulf?s reserves in Oklahoma are in the proved category (81% are PUDs) as illustrated by the accompanying chart.

Napoleonville Salt Dome Project
Proven, Probable and Possible Reserves have been calculated for Napoleonville based only on the first 8 prospects that have been proposed by the joint venture.
There are over 50 leads and prospects that have already been identified at Napoleonville and more of these will be added to the Proven, Probable and Possible categories as drilling takes place.
PROVED, PROBABLE AND POSSIBLE RESERVES
The reserves estimates were prepared by T.J. Smith & Company, Inc. Oil and Gas Consulting, Houston, Texas, USA and as such the reserves are of the Proved, Probable and Possible Reserve category as defined by the Society of Petroleum Engineers? standards.
Net Present Values (NPVs) are generated by using production attributable to working interests less royalties, operating costs, ad valorem taxes and, where appropriate, capital costs. The 30 June 2008 NYMEX oil and gas prices used, as per SEC guidelines, are US$13.353 per MMBtu for gas and US$140.00 per barrel for oil less appropriate price differentials attributable to the particular area. Due to the drop in oil and gas prices since 30 June 2008 Grand Gulf has also provided the NPVs at US$8.00 per MMBtu and US$100 per barrel and.
