Nitrogen freeze procedure expedites P&A operation in the Gulf of Mexico

A difficult P&A operation in the GOM was halted, due to a casing part below the slips. Inspection revealed damage so extensive, that further operations or well entry were impossible without changing the BOP for a larger-diameter version. Gas was also emanating from the wellbore, which required a barrier. To solve the problem and reduce NPT, a novel nitrogen freeze technique was employed.
