Isolating Potential Flow Zones During Well Construction Contains best practices for zone is olation in wells to prevent annular pressure and/or flow through or past pressure - containment barriers that are installed and verified duri ng well construction. We ll construction practices that may affect barrier sealing pe rformance are mentioned along with methods to help ensure positive effect s or to minimize any negative ones. The objectives of this guideline are two - fold. The first is to help prevent and/ or control flows just prior to, during, and after primary cementing operations to install or “set” casing and liner pipe strings in wells. The second objective is to help prevent sustained casing pressure (SCP). Th e guidance from this document covers recommendations fo r pressure - containment barrier design and installation and well construction practices that affect the zone isolation process to prevent or mitigate annular fluid flow or pressure
