چکیده    Column final tests face new challenges, and in addition to casing burst/collapse limitations, buckling occurrence creates serious problems. in case of a slight gap between mud and slurry densities, buckling initiation is inevitable. casing elongation, bending, and buckling are detailed to define column behavior while testing. buckling influences on slurry are mentioned and compared to the column without test. a new cement quality indicator is also proposed, tested, and validated via logging of wells drilled in different regions. the results are generalized to cover other situations rather than heavy sections. further, gas migration regions, depleted reservoirs, and weak zones are all examined. registrations confirm the appearance of buckling either while pumping slurry or pressure testing. a new modified casing selection method conjointly with an updated numerical technique is proposed to prevent buckling. moreover, the experimental and simulation findings confirm the reliability of the proposed technique.
