Navigator Field

Eastern Shelf of Midland Basin

Burk-Gunn Oil Co.

Dickens County, Texas, USA

Producing reservoir

L Permian Tannehill Ss

Approximate depth below surface

1200 feet (365 m)

Development techniques

Subsurface geology, Exploration geochemistry, Dipmeter

Production to date

About 3 MMB Oil

Current status

Operated by Burk-Gunn Oil Co.



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.

Navigator Cross Section

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.
