Abstract

The Papa Terra oil field is operated by Petrobras in partnership with Chevron, located 110 kilometers from the coast in deep water at Campos Basin, offshore Brazil, has an extra heavy oil formation with several challenges for its production development. The purpose of this paper is to present the innovative strategy to exploit the field, as well as the technological innovations on the FPSO (Floating Production Storage and Offloading) P-63, designed and built to process, store and export the extra heavy oil of Papa Terra field. During the lifetime of the field, each new technology applied to the project will be closely monitored by the company in order to provide useful information to be considered when designing the next offshore production units.

The strategy of developing the heavy oil field production in deep waters, using three floating units, such as the TLWP (Tension Leg Wellhead Platform) P-61, in combination with a TAD (Tender Assisted Drilling), along with the innovative technologies onboard the FPSO P-63, can be considered an innovative and very attractive concept in Brazilian oil industry.

INTRODUCTION

The Papa Terra oilfield is located in the South portion of the Campos Basin, 111 Km off Cabo Frio city, in the state of Rio de Janeiro (figure 1). The field was discovered in June 2003 and extends over an area of 183 square kilometers, in water depths varying from 400 to 1,400 meters and is estimated to contain 700 million to a billion barrels of oil equivalent. The total volume of recoverable oil is approximately 400 million barrels.

The presence of extra heavy oil with high viscosity, low gas-oil ratio (GOR) and a large amount of produced water brings extra challenges, demanding a differentiated strategy for the field development.
