## Abstract

MMS is incorporating by reference the First Edition of the American Petroleum Institute's Recommended Practice (RP) for Cementing Shallow Water Flow (SWF) Zones in Deep Water Wells (API RP 65) into MMS regulations. From 1987 to 2004, at least 113 Outer Continental Shelf (OCS) wells encountered SWF to varying degrees. While the majority of these wells experienced SWF to only a minor degree, there were instances of severe encounters resulting in abandonment of well sites and loss of wells. This action establishes best practices for cementing wells in deep water areas of the OCS that are prone to SWF.
