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. If you require any additional information, please contact me or my alternate, Gerald Murphy, at 659 -5102.

All, Well H-20 is a natural flow producer that has been identified with a rising wellhead. A recent a MIT-OA w/N2 was performed to diagnose the condition of the surface casing. The test failed on 06/13/07 and as a result the status of the well has been changed from "Operable" to "Not Operable." The well must remain shut in until the surface casing leak is mitigated. The current plan ./ forward is to perform a TIFL to evaluate the condition of the tubing. Following the evaluation of the tubing we will have to diagnose a plan to mitigate the surface casing leak before we can put the well back on production. Please call if you have any questions or concerns.
