API RP 65-1 – Cementing Shallow Water Flow Zones in Deep Water Wells, Second Edition

This recommended practice describes methods designedto prevent shallow-water flow (SWF) during and followingcementing of wells located in deep water. It is thecompilation of technology and practices developed andused by many operators around the world. Although mostof the discussion in this standard is focused on shallowwaterflow (SWF), shallow flows can be mixtures of water,gas, gas hydrates, and formation fines. There is no singlemethod of preventing shallow-water flow and many of theactivities described can require customization to fitindividual well conditions.
