The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10-404, Report of Sundry Operations.

The well has developed slow TxlA communication resulting in slow IA repressurization. The waiver has been cancelled due to the well no longer meeting waiver requirements. The well has been shut-in and is secured with a TTP. The well will be evaluated for options to mitigate the slow IA repressurization. The well is reclassified as a Trouble well. Please remove all waivered well signs and the laminated copy of the waiver from the wellhouse.
