Resumo

Para que a produção e os lucros das empresas de petróleo não diminuam, novos campos de precisam ser descobertos e explorados. Muitas dessas novas descobertas são campos offshore em águas profundas. No entanto, a queda nos preços do petróleo nos últimos anos fez com que esse tipo de exploração, que já é um desafio em si, seja ainda mais difícil, de modo que as empresas estão postergando ou até mesmo cancelando vários projetos em águas profundas. Inovação, novas tecnologias e novos conceitos de produção e processamento de petróleo e gás são necessários para viabilizar projetos em águas profundas e aumentar sua competitividade. O objetivo do presente artigo foi analisar o processamento submarino da produção de petróleo como uma estratégia para reduzir custos, tanto de capital quanto de operação, para viabilizar a exploração de campos offshore remotos. Além disso, uma discussão sobre os benefícios e desafios dessa estratégia também foi realizada. Também inclui um estudo de caso no campo de Lula, no pré-sal brasileiro. Os resultados demonstram que o uso de separação submarina tem grande potencial para reduzir o OPEX e o CAPEX em projetos offshore. O presente estudo de caso demonstra uma redução de custos devido ao investimento nos separadores de cerca de US $ 6,1 bilhões, uma redução de cerca de 6 a 12 vezes na energia necessária para elevar a produção e uma redução de cerca de 5 a 7 vezes nos gastos com gás natural como combustível para os cenários avaliados.
