NTL 1999-G11 - Approval of Acidizing Operations - June 7, 1999

This Notice to Lessees and Operators (NTL) supersedes the Letter to Lessees and Operators, dated November 19, 1993, on this subject. It updates regulatory citations and includes a statement on the Paperwork Reduction Act of 1995. The Minerals Management Service (MMS) regulation at 30 CFR 250.601 lists the well-workover operations conducted with the tree installed and that are defined as routine. According to 30 CFR 250.613, these routine well-workover operations can be conducted without MMS approval. On the other hand, any well-workover operation that is not routine cannot be conducted without MMS approval. Since it is not listed at 30 CFR 250.601, acidizing is one of those well-workover operations that requires prior MMS approval of Form MMS-124.
