Novel Single-Trip Upper Completion System Saves Rig Time in Deepwater Offshore Brazil

摘要

This paper outlines the mechanism and functioning of One Trip Upper Completion System using an hydraulic tubing compesating device (HTCD), the UST (Upper-Completion Single-trip System) that enables the integration of all equipments of an upper production string in order to run in hole in one single trip. The UST with HTCD is an upper completion system that integrates safe production string running in hole and simplified hydraulic release after connecting the lower completion equipment to the upper completion system. This paper also emphasizes the difference amongst few systems from conventional dual trip upper completion until other types of tubing seals receptacles used for single trip upper completion, stating all mechanical differences and their peculiarities This document describes field experiences of Upper-Completion Single-trip (UST) installations using Single Trip Hydraulic Tubing Compensating Device (HTCD) system and establishes a comparative analysis of rig time savings and operation differences using conventional methods compared to the UST with HTCD.
