Table 3. Time estimates for secondary operations that may be conducted if extra time is available.
| Scenario | Additional Time Needed (days) |
| 1a. Bit changes necessary for coring, logging, and casing beyond 325 mbsf* | 3.1 |
| 1b. Core, log, and case an extra 50 m of basement in the H2O reentry hole | 1.5 |
| 1c. Core, log, and case an extra 100 m of basement in the H2O reentry hole | 3.9 |
| 1d. Core, log, and case an extra 150 m of basement in the H2O reentry hole | 6.3 |
| 2. Triple APC/XCB at H20 after completion of H2O reentry hole | 3.6 |
| 3. Transit to PAT-13C and triple APC/XCB after completion of H2O reentry hole | 7.9 |
| * To deepen the H2O reentry hole significantly beyond the planned 325 mbsf will likely require a bit change for coring and a bit change for opening the hole for the 10-3/4-in casing. | |
