Chariot O&G Ramps Reserves Offshore Namibia

Chariot O&G updated its Namibian resource potential. The resource update is based upon the mapping and interpretation of the 3D seismic datasets received at the beginning of July for blocks 1811A&B in the North and blocks 2714A&B in the South and the final interpretation of the 2D seismic in its Central blocks offshore Namibia. Following this, a further 1.5 billion barrels of unrisked prospective resources have been identified, the total gross resource volume now standing at over 10 billion barrels. Chariot also reported an increased Chance of Success across the prospect and lead inventory. 

Highlights of the findings include: 

  • 2.2 billion barrels in the Northern blocks
  • 3.7 billion barrels in the Southern blocks
  • 4.1 billion barrels in the Central blocks
  • Increased confidence in rich oil prone source rock in the North - optimal environment for preserved hydrocarbon accumulation
  • Multiple structural closures identified in South - also in oil window
  • Prospects increased to 11 - current inventory: 11 prospects, 6 leads 

This volume update follows the March 2010 release when the initial potential in the Central Blocks (licenses 2312A&B and the northern halves of 2412A&B) was announced which took the total to 8.5 billion barrels of gross unrisked prospective resources. Today's announcement increases this by a further 18% to approximately 10 billion barrels. 

As announced in July, the final depth converted 3D seismic volumes covering a total area of 4,500km2 were received from the contractor, on schedule. The data was of exceptionally high quality and covered 1,500km2 over the Northern blocks and 3,000km2 over the Southern blocks (2,500km2 acquired with partners Petrobras in 2714A). The acquisition of this data has been invaluable - significantly enhancing the understanding of the geologic setting within these license areas. 

Northern Blocks 

In Block 1811A, the various Tapir structural leads are confirmed as prospects with the addition of draping fan sands in providing stratigraphic trapping upside. There is evidence of Direct Hydrocarbon Indicators (DHI's) within the data set and work is underway to quantify its significance. Further risk reduction will be substantial if these studies are concluded positively. Additionally further geologic studies have increased our confidence in the presence of a rich oil prone Cenomanian to Turonian source rock in 1811A&B which is mature for oil generation present day - this being optimal for preserved hydrocarbon accumulation. These studies also confirm our assessment of good quality turbidite sandstone reservoirs likely to be present in both Upper Cretaceous and Tertiary levels over our mapped prospective areas. 

Southern Blocks 

In Block 2714, interpretation has confirmed multiple structural closures at several target levels in the Upper Cretaceous, Albian and Barremian levels with additional stratigraphic upside mapped at the Barremian level - this is the same level as the existing Kudu field. Geologic studies have demonstrated that the likely source levels in the synrift and / or basal drift interval are presently in the oil window in the kitchen areas underlying block 2714 whereas these same oil prone source rocks are buried significantly deeper and in the gas window below the Kudu field. For this reason we believe the phase of any charge in our prospects will be oil rather than gas. 

The table below sets out the prospective resource estimates for the full Chariot inventory. The volumetrics which have led to the resource increase were based on probabilistic Monte Carlo simulations for these structures. All blocks are 100% owned and operated by Enigma Oil & Gas Exploration (Pty) Limited, a wholly owned subsidiary of Chariot, with the exception of block 2714A in the South, which is 50% owned in partnership with Petrobras.

Paul Welch, CEO commented, "I am delighted to report these newly updated resource volumes and the increased chance of success. These results are highly encouraging and serve to further underpin our conviction of the value and potential of our assets offshore Namibia. With gross mean unrisked prospective resources of over 10 billion barrels, Chariot is now a significant player in offshore West African exploration and we are very proud of our efforts and progress to date."
