Subsea Processing and Boosting in Brazil: Future Vision

Topics: Offshore

Subsea processing and boosting can be key enablers and optimization alternatives for challenging field developments whose benefits increase with water depth, flow rates, and stepouts. This paper summary focuses upon reporting new research-and-development (R&D) initiatives related to subsea processing and boosting offshore Brazil.

Introduction

In the initial exploitation stages of offshore oil and gas fields, the main concern involves the initial investment to construct the production units, drill the wells, and install all equipment necessary for production. Operators usually adopt a conventional solution at this stage, failing to view new technologies as a first alternative. Such technologies are usually considered only when they are vital for a specific field development.

For most fields in the Campos basin offshore Brazil, the main recovery mechanism from the beginning of production is waterflooding. A typical curve of produced fluids starts with the predominance of oil rising to the production plateau until the water breakthrough occurs. At this point, production presents increasing water content in the liquid stream. Therefore, because a massive water injection is necessary to maintain the pressure of the reservoir, after a few years the water cut increases considerably. Additionally, there is a need to overcome the constraints of existing platforms.
