Abstract
método para controlar o fluxo de entrada de petróleo bruto, de gás natural e/ou de outros efluentes um método para controlar o fluxo de entrada de petróleo bruto, de gás natural e/ou de outros efluentes (20) para dentro de zonas de fluxo de entrada de um poço (1) de zonas múltiplas com zonas de fluxo de entrada distintas através das quais o petróleo bruto e/ou o gás natural e/ou outro efluentes (20) são produzidos, zonas que são providas, cada uma, com um dispositivo de controle de fluxo de entrada (icd) para controlar o fluxo de entrada de fluido através da zona para dentro do poço (1), compreende: a) avaliar o fluxo de petróleo bruto, gás natural, água e/ou outros efluentes (20) a partir do poço (1); b) monitorar as variáveis de produção, incluindo a posição de cada icd e/ou a pressão de fluido em cada zona de fluxo de entrada a montante de cada icd e/ou a pressão de fluido em um tubular de poço a jusante e na vizinhança de cada icd; c) realizar um teste de poço durante a qual a produção a partir do poço (1) é variada ajustando-se sequencialmente a posição de cada um dos icds e o fluxo de petróleo bruto, gás natural e/ou outros efluentes de poço (20) é avaliado de acordo com a etapa a; d) monitorar, durante a etapa c, as variáveis de produção de acordo com a etapa b; e) derivar, a partir das etapas c e d, um modelo de estimativa de produção para cada zona de fluxo de entrada do poço (1); e f) ajustar cada icd para controlar o fluxo de entrada do petróleo bruto, gás natural e/ou outros efluentes (20) para dentro de cada zona de fluxo de entrada com base nos dados derivados a partir do modelo de estimativa de produção zonal para cada zona de fluxo de entrada do poço (1).
