# §550.116. How do I determine producibility if my well is in the Gulf of America?


If your well is in the GOA, you must follow either the procedures in [§ 550.115](/cfr/30/550.115.md) of this subpart or the procedures in this section to determine producibility.

- (a) You must write to the Regional Supervisor asking for permission to determine producibility.
- (b) You must provide or make available to the Regional Supervisor, as requested, the following log, core, analyses, and test criteria that BOEM will consider collectively:
  - (1) **A log showing sufficient porosity in the producible section.**
  - (2) **Sidewall cores and core analyses that show that the section is capable of producing oil or gas.**
  - (3) Wireline formation test and/or mud-logging analyses that show that the section is capable of producing oil or gas.
  - (4) A resistivity or induction electric log of the well showing a minimum of 15 feet (true vertical thickness except for horizontal wells) of producible sand in one section.
- (c) No section that you count as producible under [paragraph (b)(4)](#b-4) of this section may include any interval that appears to be water saturated.
- (d) Each section you count as producible under [paragraph (b)(4)](#b-4) of this section must exhibit:
  - (1) A minimum true resistivity ratio of the producible section to the nearest clean or water-bearing sand of at least 5:1; and
  - (2) **One of the following—**
    - (i) Electrical spontaneous potential exceeding 20-negative millivolts beyond the shale baseline; or
    - (ii) Gamma ray log deflection of at least 70 percent of the maximum gamma ray deflection in the nearest clean water-bearing sand—if mud conditions prevent a 20-negative millivolt reading beyond the shale baseline.
