Abstract

The Giant field of Roncador was by far the largest discovery made in Brazil in the 90's. Its approved Development Plan relies on its separation in four modules, due to significant reserves involved and difference among oil characteristics found. The field is already producing with SS P-52 and FPSO P-54 since 2007, for modules IA and II respectively. Soon the field will also count with SS P-55, which will start operations for Module III in 2013 and FPSO P-62, which will have its first oil for Module IV at the first quarter of 2014, and represents the focus of this work.

The Roncador Module IV is located at the center of the block, placed on the northeast of Campos Basin, 125 KM far away from the Brazilian coast. Currently, its reserves are over 500 MM boe, saturated with 18 ° API heavy oil. The wells are being constructed in ultra deep waters, with variations depths between 1650 and 1750 meters of water column.

This paper presents an overview of the project, including strategic drivers adopted on its design, which sought to mitigate risks and reduce deployment costs, as well as its scope and the journey since the selection of alternatives through the current status, with the FPSO P-62 under final phase of construction and assembling at the Estaleiro Atlântico Sul Shipyard in Recife and near the beginning of its operation in the Roncador field. The operation in advance of four wells (three producers and an injector one) using the already installed infrastructure of the field, will also be presented in this work.

Introduction

Roncador giant field, with an area of ??109 km2 and discovered through the exploratory well 1-RJS-436A in October/1996, is located in the northern area of Campos Basin, northeast of Albacora and Albacora Leste fields, lying about 125 km from São Tomé Cape, in the north coast of Rio de Janeiro State.

The field is associated with a major fault system with major dimensions and dominantly extensional profile. Due to the large areal extent, the large volume of oil in place, different types of oil and limited processing capability in deep water the development of the field was divided into 4 modules (Fig 1) as follows:

  • Module 1A, saturated with oil of 28 ° API, which was divided into two phases: Phase 1, which began production in December 2002, and Phase 2, which began production in November 2007.

  • Module 2, saturated with oil of 18 ° API, which started production in December 2007.

  • Module 3, saturated with oil of 22 ° API, which production start forecast is end 2013.

  • Module 4, saturated with oil of 18 ° API, which will be the focus of this work, still in progress. As a development strategy, the production of the module started in December 2012 due to an Early Oil Production Program, with a subsea tie back to existing facilities nearby module 4. However, the main objective is to develop the field through the FPSO P-62, which is expected to start the early 2014.
