Due to the need for a grease syringe method in the setup to ensure the blowout preventer that can seal or cover over the braided curves of the wire, braided lines are far more involved than slacklines. The upper main valve on the Christmas tree can only cut slacklines, thus it also needs an extra or additional shear seal blowout preventer as a third or tertiary obstacle. Both the coreless kind used for fishing and the electric line used for Well Intervention logging and perforating are braided lines.
Depending on how wellheads work and are maintained, maintenance issues for Christmas trees and wellheads may differ. Greasing and pressure testing to may be the only components of the annual maintenance that is scheduled.
