San Marco Permit - Exploration Prospects

Two prospects have so far been identified in the San Marco permit. They are formed by a combination of structural and stratigraphic closure that lie in the synclines between structural highs. Stratic holds a 100% working interest in the San Marco permit.

 

Roesetta Prospect

The main objective of the prospect is a combination trap that is a three-way dip closure with an updip stratigraphic pinch-out onto the Alfonsine structure. The potential reservoirs are several onlapping sequences of Lower to Upper Pilocene sands. These sands are most likely the result of a similar depositional environment to that in the reservoir sequence penetrated at the Abbadesse/Longanesi field. The prospect area is therefore expected to have similar reservoirs properties to the Abbadesse/Longanesi area but the seismic data suggest the net reservoir thickness will be thinner. The apparent traps are well displayed on existing seismic lines.

 

The Rosetta prospect has been independently assessed by Ryder Scott as having a resource range of 5-50 bcf, with a most likely estimate of 15.6 bcf. The prospect is considered to be of low to moderate risk and is situated at a depth of approximately 2000 metres.

 

Boncellino Prospects

There are two separate plays in this area, one structural and one stratigraphic.

 

The first play is a thrust feature probably related to the Cotgnola Field nearby to the west.  The objective sand is seen in the Cotgnola-8 well drilled in 1954. The sand is designated a Miocene-age, fairly think and fairly well developed sand but wet. The prospect is slightly structurally higher. The prospect size has been independently assessed by Ryder Scott as having a resource range of 5-23 bcf, with a most likely estimate of 12.1 bcf and is considered to be of moderate risk. The prospect is situated at a depth of approximately 1600 metres.

 

The second play is a feature interpreted as a mounded sand deposit: a localized structure with closure created by differential compaction. The prospect size has been independently assessed by Ryder Scott as having a resource range of 5-32 bcf, with a most likely estimate of 15.5 bcf and is considered to be of moderate risk. The prospect is situated at a depth of approximately 1300 metres.

 

It is not possible to test the two plays in an optimal position with a single straight well but a deviated well could possibly be designed to penetrate each prospect in a favourable position.
