Unformatted text preview: ximately 14.3 ppg synthetic‐based mud (“SBM”). Hydrocarbons, if present in the annulus, would have exhibited a much lower density. When fluids of different densities meet at an opening, gravity and the “u‐tube” effect typically cause the more dense fluid DDII IADC Report, 9/11/10 (TRN‐USCG_MMS‐00043342). DDII IADC Report, 9/11/10 (TRN‐USCG_MMS‐00043342). A “well hanger” is a long string of production casing that hangs from a casing hanger inside the wellhead. 156 DDII IADC Report 9/22/10 ‐ TRN‐USCG_MMS‐00043388. An isolation scanner tool is used to evaluate a cement job by taking measurements to help distinguish solids from liquids in the wellbore. The tool can identify potential channeling and can evaluate whether a cement job has achieved zonal isolation. 157 DDII IADC Report 10/7/10 (TRN‐USCG_MMS‐00043449). This was done using a perforating gun and well testing equipment. 154 155 63 to flow into the space occupied by the lower density fluid. No “u‐tube” flow of the 14.3 ppg mud from the casing to the annulus occurred on October 7, indicating that hydrocarbons were not pre...
