The Morondava prospect comprises 6,825 square kilometers (1.7 million acres). It appears to have three large potential structures; two identified by the new 2009 seismic acquisition and one confirmed by the review of the existing older seismic data. Morondava has two wells that were drilled in the 1980’s. One had shows of oil and the other was a dry hole.
The two Prospective Areas cover over 31,000 acres in two portions of the block.
•Three structural closures have been mapped.
♦The Saronanala Lead consists of two structures in the Bemaraha carbonate section separated by a narrow graben.
•Saronanala East “A” > 8,700 acres
•Saronanala East “B” > 8,300 acres
♦Namakia East Central Closure > 14,000 acres
•Reservoirs expected in the Isalo II sandstones and Bemaraha carbonates.
•Gas and minor oil shows present in down-dip wells within mapped reservoir intervals.
•Hydrocarbon charge and structural trap timing remain very high risks for prospects on Block 3106.
An example of the Saronanala East A and B cross section indicates the graben area between the two structures.
The Namakia East Lead is a single large closure in the Bemaraha carbonate and the one well drilled down structure is shown on Line 31 and is east of the structural closure.
Conclusion
•These mapped stratigraphic zones do not represent drillable prospects at this time.
•Oil/gas shows downdip of the prospective areas are encouraging indications of an active petroleum system, but they do not definitively support the existence of a hydrocarbon trap.
•Most wells that have penetrated the Bemaraha carbonates have had gas shows up to C5.
•The three structural closures now mapped on B3106 contain an estimated OOIP of close to 5 Billion BO.
•To ascertain the existence and extent of any hydrocarbon accumulations, it is the plan in 2010 to:
♦Acquire two GORE surface micro seepage surveys, each roughly 160 sq km over the Saronanala East “A” and “B” closures, where MOL’s 2009 seismic survey was shot, and over the Namakia East structure.
