Abstract

The recovery and redeployment of Christmas trees is an important factor in the economics of subsea field development because the time and expense involved in well maintenance is a major cost item. This paper examines 18 trees that have been recovered and redeployed by Petrobras off the Campos Basin in Brazil and analyzes the reasons for recovery and the time involved in completion, reinstallation and tree maintenance operations. As a rule, tree maintenance has been very minor and the tree redeployment operation has generally been performed in slightly less time than the initial installation. The data presented here are useful for estimating field operating costs of future subsea field developments. Additionally, the recommendations given, based on the experience analyzed, will help design completions that are faster and less expensive to install and maintain, particularly for deepwaters.
