§550.1154. How do I determine if my reservoir is sensitive?
30 C.F.R. § 550.1154
You must determine whether each reservoir is sensitive. You must classify the reservoir as sensitive if:
Under initial conditions it is an oil reservoir with an associated gas cap;
At any time there are near-critical fluids; or
The reservoir is undergoing enhanced recovery.
For the purposes of this subpart, near-critical fluids are—
Those fluids that occur in high temperature, high-pressure reservoirs where it is not possible to define the liquid-gas contact; or
Fluids in reservoirs that are near bubble point or dew point conditions.
The Regional Supervisor may reclassify a reservoir when available information warrants reclassification.
If available information indicates that a reservoir previously classified as non-sensitive is now sensitive, you must submit a request to the Regional Supervisor to reclassify the reservoir. You must include supporting information, as listed in the table in § 550.1167, with your request.
If information indicates that a reservoir previously classified as sensitive is now non-sensitive, you may submit a request to the Regional Supervisor to reclassify the reservoir. You must include supporting information, as listed in the table in § 550.1167, with your request.
