Abstract

sistema e método para regular a pressão dentro de um espaço anular de poço. trata-se do gerenciamento de pressão dentro de um poço submarino conforme a temperatura dentro do poço oscila. o gerenciamento da pressão atenua o estresse da estrutura do poço ocasionado pela pressão. para gerenciar a pressão, o fluido é recebido e/ou fornecido para o poço a fim de reduzir e/ou aumentar a pressão dentro do poço.
