General

This document provides guidance for the design, placement, and verification of cement plugs in wells that are to be temporarily or permanently abandoned. Wells that are temporarily abandoned have intent to re-enter in the future. The placement of barriers vary depending on whether the well is to be temporarily or permanently abandoned.

The information in this document is general in nature. Wellbore plugging and abandonment practices will vary with regulation, well type, and purpose. Sound engineering and operational practices should be applied to each plugging operation. Plug lengths are not considered in this document. Local regulations must be considered in the design as they may dictate the length of cement to be placed below or above specific intervals, or both.
