The well had come to our attention because it had ceased gas production, and bradenhead pressures were observed between 150-300 psi, indicating a possible casing leak. We then set a cast iron bridge plug at 4150’, and a wireline truck perforated the 4-1/2” with 3 shots, 120 deg phasing at a depth of 4082’. A cement retainer was set at 3900’, tubing was stung into retainer, and water was pumped down tubing to get an injection rate, which was found to be 2.25 bbls at 550 psi. The next day (07/25/2013) we rigged up Halliburton for the cement squeeze, and pumped 40 bbls of a mud flush to clean the hole, then 5 bbls of water as a spacer, followed by 345 sacks of 13.5 ppg Class G cement, and a 50 sack, 15.8 ppg, Class G cement was tailed in last. 14 bbls of freshwater was pumped to displace the cement from the tubing into the casing holes and perforations, and 8 hesitation squeezes where performed over a period of 2 hrs, going up in 100 psi increments to a final pressure of 1006 psi (see attached Post Job Report). We had planned the cement volumes based on annular backside capacity of the 4-1/2” from 4082’, up 500’ into the surface casing. We then waited 3.5 days to allow ample time for the cement to set up, and on 07/29/2013 we ran in the casing with a bit to drill cement out and tagged hard cement at 3912’. We drilled up cement, pressure testing with every new joint of tubing (30’) placed in hole, to 1000 psi, plus the hydrostatic pressure of the water column exerted on the bottom. We drilled cement all the way to the cast iron bridge plug, with a last pressure test to 1000 psi surface pressure + (0.433 psi/ft X 4151’, hydrostatic pressure of water) = 2797 psi at 4151’. Next day we had FMC run a wireline Cement Bond Log, and observed a top of cement at 1070’, approx 1100’ of cement into surface casing. Bradenhead monitoring has been on-going since workover operations, and the bradenhead pressures have been near zero, indicating a successful cement squeeze for casing repair and pressure isolation. Thread was being aborted.
