2) Pump surface casing shoe plug at 272' only after isolation has been verified. If surface casing cement is not circulated to surface, shut-in, WOC 4 hours then tag plug – must be at 46'’ or shallower and provide a minimum of 10 sx plug at the surface.
3) Leave at least 100’ of cement in the wellbore for each plug without mechanical isolation.
4) After cut and prior to cap, verify isolation by either a 15 minute bubble test or 15 minute optical gas imaging recording. If there is indication of flow contact ECMC Engineering. Provide a statement on the 6SRA which method was used and what was observed. Retain records of final isolation test for 5 years.
