By the final quarter of 2011, production from the deepwater Bijupira and Salema (BJSA) fields was in rapid decline. As the operator’s study to improve production matured over the next 15 months to the final investment decision (FID), the BJSA Redevelopment Project became a brownfield flagship project for the operator. One year after FID, the opportunity came to fruition, achieving first oil on 2 February 2014. The execution of the project, addressed in the complete paper, required innovation in engineering and procurement strategy.

Introduction

The BJSA fields were discovered in 1990 and are located 250 km east of Rio de Janeiro. The blocks range in depth from 480 to 880 m.
