Best practices for the abandonment of pipelines

Abstract

Pipeline regulations implemented in 2006 require that licensees register all pipelines. Training must also be provided for ground disturbance supervisors. In addition, signage must be maintained on abandoned pipelines, and discontinued pipelines must be properly isolated. Corrosion control and internal inhibition is required for discontinued lines. However, pipelines are often neglected during the well abandonment process. This presentation provided recommendations for coordinating well and pipeline abandonment processes. Pipeline ends can be located, depressurized, flushed and purged while wells are being abandoned. Contaminated soils around the wells can also be identified prior to reclamation activities. Administrative reviews must be conducted in order to provide accurate information on pipeline location, reclamation certification, and line break history. Field operation files must be reviewed before preliminary field work is conducted. Site inspections should be used to determine if all ends of the line are accessible. Landowners and occupants near the line must also be notified, and relevant documentation must be obtained. Skilled technicians must be used to assess the lines for obstructions as well as to cut and cap the lines after removing risers. The presentation also examined issues related to pressure change, movement, cold tapping, and live dead legs. tabs., figs.
