The encapsulation of downhole components such as Hydraulic Control Lines, Single Line Encapsulation, Dual-Line Encapsulation (FLATPACK), Triple-Line Encapsulation (FLATPACK) has become prevalent in downhole applications. The overlaying of plastic provides several benefits that help to ensure a successful completion.
