Abstract The Salema field, a waterflood development off the coast of Brazil (Campos Basin) has been suffering from early water breakthrough and poor sweep on the south part of the field. In an attempt to increase the sweep efficiency, a novel in-depth waterflood conformance control technology commercialized by Tiorco (Nalco company) as Brightwater®6 has been selected. This paper describes the feasibility, maturation, execution, monitoring and results of the first trial in Brazil (July 2009), which is also the first for Shell worldwide. We will discuss reservoir simulation and lab work (core tests, sand-pack tests…) that lead to the decision of performing the field trial. The offshore set-up and pumping job will be described briefly. Finally surveillance techniques and results to date will be presented.
