Embodiments relate generally to systems and methods for decommissioning a pipeline. The system may comprise a mechanical assembly and chemical assembly. The mechanical assembly may include a main body and contact assembly. When the mechanical assembly is provided in the pipeline, the contact assembly is configurable to contact with the pipeline's interior wall. The chemical assembly may be arranged serially in line with the mechanical assembly. The chemical assembly may include a front section having a cross-sectional portion configurable to resemble the cross-section of the pipeline. The chemical assembly may also include a rear section having a cross-sectional portion. The front and rear sections may be arranged in such a way that, when the chemical assembly is provided in the pipeline, the cross-sectional portions of the front and rear sections cooperate with the pipeline's interior wall to form a chamber operable to receive and house a removal medium.

Abstract

A completion system delivers lifting gas supplied from the surface via a casing annulus through the packer for injecting to the wellbore at bottom hole. So, lifting gas maximizes hydrocarbon producing from a subterranean well while maintaining integrity and serviceability as a typical gas lift well. More specifically, a single completion system uses the same tubing string for both producing the well and delivering lifting gas to the wellbore at downhole. The top section of the tubing is used for producing the well, while the bottom section of the tubing is used for delivering lifting gas for injecting at bottom hole. The lifting gas will be injected to the wellbore proximately at perforation intervals for helping unloading liquid and producing the well. The use of modified equipment named “TK Bypass Mandrel” and “JP Bypass Nipple Sub” allows delivering and controlling of the lifting gas for injecting at bottom hole via a single tubing string.
