30 CFR §250.874

1. (a)Adhere to the water injection requirements described in API RP 14C (incorporated by reference as specified in § 250.198) for the water injection equipment located on the platform. In accordance with § 250.830, either a surface-controlled SSSV or a water injection valve (WIV) that is self-activated and not controlled by emergency shut-down (ESD) or sensor activation must be installed in a subsea water injection well.
2. (b)Equip a water injection pipeline with a surface FSV and water injection shutdown valve (WISDV) on the surface facility.
3. (c)Install a PSHL sensor upstream (in-board) of the FSV and WISDV.
4. (d)Use subsea tree(s), wellhead(s), connector(s), and tree valves, and surface-controlled SSSV or WIV associated with a water injection system that are rated for the maximum anticipated injection pressure.
5. (e)Consider the effects of hydrogen sulfide (H2S) when designing your water flood system, as required by § 250.805.
6. (f)Follow the valve closure times and hydraulic bleed requirements according to your approved DWOP for the following:
   1. (1)Electro-hydraulic control system with water injection,
   2. (2)Electro-hydraulic control system with water injection with loss of communications, and
   3. (3)Direct-hydraulic control system with water injection.
7. (g)Comply with the following injection valve testing requirements:
   1. (1)You must test your injection valves as provided in the following table:
   2. (2)If a designated USV on a water injection well fails the applicable test under § 250.880(c)(4)(ii), you must notify the appropriate District Manager and request approval to designate another ANSI/API Spec 6A and API Spec. 6AV1 (both incorporated by reference in § 250.198) certified subsea valve as your USV.
   3. (3)If a USV on a water injection well fails the test and the surface-controlled SSSV or WIV cannot be tested as required under (g)(1)(ii) of this section because of low reservoir pressure, you must submit a request to the appropriate District Manager with an alternative plan that ensures subsea shutdown capabilities.
8. (h)If you experience a loss of communications during water injection operations, you must comply with the following:
   1. (1)Notify the appropriate District Manager within 12 hours after detecting loss of communication; and
   2. (2)Obtain approval from the appropriate District Manager to continue to inject during the loss of communication.
