Matra Announces 2D & 3D Seismic on Sokolovskoe Field

Source: 3/19/2013, Location: Asia

Matra Petroleum has announced the results of the seismic survey conducted on its 100% owned Sokolovskoe oil field in Orenburg, Russia. The survey included 100 kms of 2D seismic and 60 sq kms of 3D seismic.

Field works, as well as the processing and interpretation of seismic data, have been executed to the highest technical and professional level, with the selected contractors possessing extensive experience of providing analogues services to major Russian oil companies in the Orenburg region. The quality of the completed works on Sokolovskoye field has fully met the objectives set by the Company.

The following interpretation phase works enabled us to correctly determine the configuration of the target horizons and reduce uncertainty in the range of potential reserves:

· Databases of the explored area were developed;
· Stratigraphic control of the reflecting boundaries was carried out with the use of well logging data, well-velocity survey and sonic logging of wells A-11, A-12, A-13..
· Top of subsalt anhydriteof Irenian horizon was selected as vertical shallowest reflector. Mapping was prepared on the basis of target reflecting boundaries with the use of slowness maps and interval velocity maps.

Seismic results have determined the complexity of the field configuration compared to what was previously mapped as one big structure. The seismic data interpretation identified that the Aphoninsky reservoir of the Sokolovskoye field splits into four separate domes within the boundaries of the license area from south-west to north-east.

Domes one and two (wells A-12 and A-13), that may be classified as oil reserves, are controlled by regional faults on the west. Dome two is limited by a downfold and local faults system on the east.

Domes three and four, that may be classified as prospective resources and are controlled by downfolds and the wells from the nearby Olshanskoye field, encountered the Aphonensky reservoir below anticipated oil water contact. We believe that further exploration potential exists in these two structures in the northeast segment of the license area.

In the light of the new seismic data and the results from wells A-12 and A-13 the Company will prepare a Field Development Plan for Sokolovskoye field. Upon the completion of the Field Development Plan Matra will commission an independent Competent Persons Report. This will provide an updated reserves figure for the areas drilled by wells A-12 and A-13. It will also provide a resources estimate for the prospective structures.

Maxim Barskiy, Chief Executive of Matra commented:

'The improved understanding of the Sokolovskoe oil field will be extremely valuable as we assess the future potential of the field and how to best allocate Matra's resources going forward.'
