Mediterranean Oil & Gas announced that, following the successful appraisal of Ombrina Mare oil and gas discovery independent reserve engineers, Studio Ingegneria Mineraria ("SIM"), have certified 6.5 Bcf of Proven plus Probable (P1 + P2) gas reserves in the field. A further 10 Bcf in possible gas reserves ("P3") associated with the Ombrina Mare Field and best case prospective resources in the BR269 Permit have also been assessed.
Gas Reserves and Resources certification
The Company has now completed a full technical re-assessment of the Pliocene gas sand complex. The reassessment included re-interpretation of the OM1 and OM2 logs and the 2D and 3D seismic from the permit area and detailed mapping of all the encountered gas sand levels. SIM has carried out an independent reserve calculation on the gas sands, in accordance with the SPE/WPC Standard which requires the application of the 2007 Petroleum Resources Management System standards. SIM has now certified the following Reserves and Resources in the Ombrina Mare Pliocene gas complex:
The Pliocene gas levels of the Ombrina Mare field are constituted by thin sand levels in the upper sequence and thick sand levels in the lower sequence with generally high water saturation and good porosity. The gas bearing sand levels cover a wide area and are not all vertically stacked. The calculation was based on 11 selected gas levels from the 16 gas levels intersected by OM2.
Additional Gas Resources in the Permit Area
The Permit has significant upside for gas beyond the certified 2P reserves. The upside comes from:
SIM identified 5.8 Bcf of additional gas upside in the main Ombrina Mare field area comprising possible reserves (P3) of 2.9 Bcf and best case prospective resources of 2.8 Bcf from the two main prospects overlying the main field. The difference in the sums is due to rounding.
In addition to the gas reserves and resources overlaying the main Ombrina Mare Field which were certified by SIM, the Company has assessed other significant gas prospects in the Permit area and identified an estimated further 4 Bcf of best case gas prospective resources.
There are additional unappraised structures on the Permit (notably OM South and OM South East) which are still being reassessed. Once this process is completed the Company will be able to announce revised prospective oil resources numbers.
The Company is considering development models utilising 2 or 3 gas production wells to produce the 6.5 Bcf of 2P gas reserves from Ombrina Mare as well as to appraise the identified 5.8 Bcf of potential P3 and prospective resources upside. Subject to a successful appraisal, the same wells would be utilized to produce these resources and P3 reserves. At least two of the proposed gas production wells could be drilled from the oil production platform with a double completion (oil and gas). This would optimize the additional capex required for the total development of the oil and gas field.
Ombrina Mare Operational Update
The Company has continued with its capital works program at Ombrina Mare. The set up of a tripod temporary platform at the OM2 well head is progressing well and the platform is close to completion. This platform will allow well inspection and maintenance until the field is developed and production can commence. Photographs of progressive work on the temporary structure have been posted on MOG's web site.
Engineering consultants have been appointed to assist MOG in the preparation of the field development plan and the production license application. The feasibility study on the field development is progressing as scheduled and the Company anticipates that it will be able to complete a development plan, which provides for development of the Pliocene gas complex at the same time as the oil field, in time to allow the submission of the application for the Production Concession to the Italian Authorities as scheduled by November 2008.
