Update on PEL 82 Licence, South Australia
Increased Prospectivity for Hydrocarbon Discoveries
Meridian Petroleum (AIM : MRP), the oil and gas exploration and production company with producing assets in the USA and exploration licences in Australia, announces initial results and key conclusions from its 3D seismic survey on the PEL 82 licence in the onshore Otway Basin, South Australia, and the next steps in the further development of the licence.
Key Points
Background
Data Processing and Quality
The 3D seismic survey covering 88 square km of the PEL 82 licence was completed at the end of March 2009. Complex data processing was necessary to overcome interference from shallow cavernous limestone strata which severely impaired the clarity of the older 2D data. Extra time and effort was expended to attenuate the impact of this. The resultant quality of the data showed substantial improvement over the 2D data at the deeper target horizons of the Waarre/Flaxman sands. At shallower depths, the 2D data remains better, and the combination of the new 3D with the re-processed 2D has provided the company with a much enhanced and more detailed view of the structure and prospects for the licence.
Data Interpretation
The Company engaged the services of two companies to provide data analysis and interpretation, using individuals with substantial experience of Australia generally and the Otway Basin in particular. Interpretation began in early July and initial reports have now been received from both parties. The two completely independent interpretations have identified the same prospective structures, giving Meridian confidence that the structural analysis is correct. Further interpretation and refinement will continue.
Current Assessment
The initial reports have highlighted a number of features which the Company will need to consider during the next stages in the development of the licence
The fault lines which were visible to shallow depths on the re-processed 2D are now much more clearly mapped at depth, providing enhanced definition of the prospective hydrocarbon traps
As a result of the clearer mapping of the faults, the three structures identified by the 2D seismic are now seen to be more complex, and there are now nine identifiable traps within the survey area. Five of these are Flaxman sandstone and four are in the deeper Waarre sandstone. The four Waarre prospects all directly underlie Flaxman prospects, which significantly improves the chances of economic discoveries
Sophisticated analysis indicates that the faulting has not compromised top seal closure on most structures, with few incidences of cross fault spill points.
Detailed mapping of the 3D seismic has revealed a positive relationship between seismic amplitude anomalies and prospective structures, particularly for the Waarre sandstone.
Overall, the analysis to date tends to suggest that there are enhanced prospects for hydrocarbon discoveries on PEL 82 with a greater number of reservoir opportunities giving more options for drilling. Identification of the best drilling locations is therefore a critical aspect of the next phase.
Next Steps
Continued analysis and interpretation to assess risked volumetrics and identify primary drilling locations
Extend analysis of the 3D across the entire licence area by incorporating the 2D interpretation.
Renewal of the licence for a further 5 year period from early September with compulsory relinquishment of 50% of the total PEL 82 area.
Discussions with potential partners in a drilling programme. Representatives of the Company will be in Australia at the end of August/early September for a number of arranged meetings with prospective partners.
Stephen Gutteridge, Chairman of Meridian, said:
"We are very pleased with the results of the 3D seismic and the extra insight that this has given us into the PEL 82 licence. The prospects for hydrocarbon discoveries have been appreciably enhanced by this work and there is clearly the possibility of sizeable and multiple discoveries. Whilst further analysis of the data needs to continue, there is now a focus on developing the drilling plan, in conjunction with potential partners and the South Australian authorities."
