OML 115 Exploration Activity for 2006

In 2006, the OML 115 project team conducted seismic and geologic studies resulting in the definition of four confirmed exploratory drilling prospects and three to four potential exploration drilling prospects (leads). They are as follows:

• Mapped 9 separate Akata horizons in the opportunity and created depth structure maps on same.
• Created flattened volumes using the 9 horizons and created time slice maps showing amplitude variations correlative with reservoir.
• Made reservoir interpretation on the slice maps and created polygons outlining probable reservoir distribution in the trap.
• Created a minibasin depositional model to explain the discrete and distributed variation in amplitude bodies seen on the slice maps discrete are channels and distrbuted amplitudes are lobes.
• Calculated sweetness volume to compare back to well control at Ameena 1 for reservoir derisking
• Created several geologic scenarios for trap fill and assessed risk on each.
• Used risk profiles to calculate resource distributions to characterize the potential of the trap.

• Created a seismic difference cube to assess the structural conformance of amplitudes in the two shallow D1 opportunities at Ameena North and Okwok South.
• Okwok South structure displayed an amplitude character conformable with structure and the Ameena North structure displayed a variable amplitude response.

• Mapped and additional two horizons that corresponded to probable reservoir in the Biafra North trap and generated time structure maps
• Created interval extractions between the mapped horizons and used the amplitude response and distribution to generate reservoir distribution polygons.
• Created reservoir model to explain the distribution of amplitudes observed in the trap.
• Calculated volumes based on polygons conforming to different amplitude shutoffs within the trap.  Amplitude shutoffs were correlated with probable hydrocarbon contacts for each interval.

• Mapped 4 additional surfaces blockwide and created amplitude extractions in windows around the surfaces to characterized reservoir distribution across the block through time. 
• Created time structure maps to observe the coincidence of reservoir and structuring to identify three to four additional leads on the block
