... Abstract Cementing operations consists of placing cement slurries between casing-casing and casing-formation to achieve multiple objectives including zonal isolation, corrosion resistance, isolation of water bearing formations, etc. Cement slurries are tailored in the laboratory environment...

... gas sand is compartmentalized between two production packers and has a sliding sleeve door (SSD) for zonal isolation. The bottom oil sand is below tubing and has resin consolidation for sand control. The upper completion string has a circulation SSD. The well was shut after depletion of the oil zone...

... designs. Over the years, regulatory and normative requirements have evolved to ensure safety and environmental protection up to the surface. Isolation must be demonstrated after well construction, as well as at the end of the well's life before it is plugged and abandoned. Cement bond log (CBL...

... Inline isolation involves pigging an isolation tool to the desired position inside the pipeline and establishing the isolation at the identified point. The isolation tool is introduced into the pipeline the same way as a pig, through the closure and pig trap. Isolation plugs can form a double...

The standard specifically describes the requirements for well decommissioning in regards to well location, well details, method of isolation and verification along with interpretation of the requirements. The legal basis for this standard is provided...
