Christmas Tree Exchange Program

To address changing well conditions

During the course of production, conditions may change, either due to reduction of reservoir pressure below the threshold required for natural flow or the souring of production fluid in the field. Christmas trees in place may not be suitable for the well’s current condition and may need to be changed.

Wells requiring artificial lift

For wells that no longer produce naturally and require artificial lift, we can remove the production tree and install artificial lift equipment in its place. The original Christmas tree would be returned to Cameron, and a service fee applied to restore the equipment to working condition. The equipment would then be stored, ready for installation on a new well that flows naturally.

Wells requiring trees with new specifications

Christmas trees can be changed out from the production choke to the top of the tubing spool. Another option might be to change out the equipment from the Christmas tree and production choke and leave the tubing hanger and spool in place because they may have been rated to meet more aggressive service conditions. For a 20- to 30-well large-bore completion, Cameron and the operator might agree to manufacture and produce 10 Christmas trees to the new specifications for purchase. Cameron could then remanufacture or upgrade the returned equipment from the first 10 wells to enable the operator to replace all the Christmas trees on a predetermined workover schedule.

This would minimize lost production and intervention and reduce hazard exposure and lead time. It could also mean a possible reduction in total equipment cost, based on using refurbished equipment versus new. The remaining 10 trees that were removed from the wells could be remanufactured to new specifications and held as customer property for the next project. Stringent acceptance criteria would be set for the used equipment.

Various options for refurbishment exist, some taking into consideration whether certain individual components are rated for more aggressive service conditions. The operator and Cameron professionals would determine the advantages of these options.
