Navigator field was discovered using integrated modeling.
Geomorphology, subsurface geology, near-surface geochemistry, electric logs, sidewall cores, and FMS-FMI dipmeter played important roles in discovery and development of this stratigraphic sandstone oil reservoir.
Findings of this study were:
• The complex sandstone reservoirs were variable thickness and discontinuous.
• Surface water channels (creeks) were apparent surface expressions of fractures or faults.
• Hydrocarbon conduction to the surface by fractures was indicated by high concentrations of 2-Ring PAC (as naphthalene) near field limits.
• C2 Paraffin (ethane) data showed high concentrations over apparent fractures and also elevated concentrations over the productive reservoir.
