NAC445A.910. Factors for determining logging and testing requirements for Class II wells.

To determine the logging and testing requirements for Class II wells, the Director will consider:

     1. For surface casing intended to protect underground sources of drinking water in areas where the lithology has not been determined:

     (a) Electric and caliper logs before casing is installed; and

     (b) A cement bond, temperature or density log after the casing is set and cemented.

     2. For intermediate and long strings of casing intended to facilitate injection:

     (a) Electric, porosity and gamma ray logs before the casing is installed;

     (b) Fracture finder logs; and

     (c) A cement bond, temperature or density log after the casing is set and cemented.
