You must classify the reservoir as sensitive if:\n(1) Under initial conditions it is an oil reservoir with an associated gas cap;\n(2) At any time there are near-critical fluids; or\n(3) The reservoir is undergoing enhanced recovery.\n(b) For the purposes of this subpart, near-critical fluids are:\n(1) Those fluids that occur in high temperature, high-pressure reservoirs where it is not possible to define the liquid-gas contact; or\n(2) Fluids in reservoirs that are near bubble point or dew point conditions.\n(c) The Regional Supervisor may reclassify a reservoir when available information warrants reclassification.\n(d) 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.\n(e) 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.
