NTL 2000-G22 - Subsalt Lease Term Extension - December 22, 2000

The current geophysical processing and imaging technology may require longer than normal timeframes to provide an accurate image of a potential subsalt objective. The application of 3D pre-stack depth migration technology is critical to successful subsalt imaging and potential hydrocarbon reservoir identification. If circumstances warrant, this NTL would allow you to maintain your lease past its term by granting additional time, pursuant to 30 CFR 250.180(e), to refine subsalt imaging techniques as well as the processing and interpretation of such imaging. This lease extension applies to a Gulf of Mexico lease that has a subsalt objective as evidenced by either geophysical imaging or geologic information, or both, provided to us by you.
