When used in this subpart, the following terms shall have the meanings given below:

Expected surface pressure means the highest pressure predicted to be exerted upon the surface of a well. In calculating expected surface pressure, you must consider reservoir pressure as well as applied surface pressure.

Routine operations mean any of the following operations conducted on a well with the tree installed:

1. (a) Cutting paraffin;
2. (b) Removing and setting pump-through-type tubing plugs, gas-lift valves, and subsurface safety valves which can be removed by wireline operations;
3. (c) Bailing sand;
4. (d) Pressure surveys;
5. (e) Swabbing;
6. (f) Scale or corrosion treatment;
7. (g) Caliper and gauge surveys;
8. (h) Corrosion inhibitor treatment;
9. (i) Removing or replacing subsurface pumps;
10. (j) Through-tubing logging (diagnostics);
11. (k) Wireline fishing; and
12. (l) Setting and retrieving other subsurface flow-control devices.
13. (m) Acid treatments.

Workover operations mean the work conducted on wells after the initial completion for the purpose of maintaining or restoring the productivity of a well.
