Introduction to OilKey
4. OilKey Consulting
Geomodeling & Reservoir Characterization
OilKey offer to build and/or to review the whole static modeling workflow in
order to determine the Hydrocarbons in Place value range (P10-P50-P90) to be
used for analytical/dynamic modeling and/or Field Development Plans.

Some examples
• Ghana: offshore, mid-late Campanian oil and gas bearing lower slope turbidites. Structural-
stratigraphic traps [PETREL]
• Italy: offshore, Adriatic and Mediterranean seas multilayered (thin layers) distal Pleistocene gas
bearing turbidites. Structural-stratigraphic traps [PETREL]
• Nigeria: offshore, oil and gas bearing estuarine/tidal dominated deltaic sands, including upper and
lower shore-face, channel facies, shale and heterolithics. Traps related to highly complex crestal
collapsed rollover anticlines [PETREL]
• Spain: offshore, structurally complex gas bearing Cretaceous carbonates deposited on a shallow water
platform, strongly affected by the formation of intra-platform basins and relative changes in sea level.
Shoals, inner shoals, sand aprons, self chalks and breccias facies [RMS]
