Abstract

MéTODO PARA TESTAR UMA FORMAçãO SUBTERRáNEA PENETRADA POR UM FURO DE POçO, E MéTODO PARA A REALIZAçãO DE TESTES DE UMA FORMAçãO SUBTERRáNEA PENETRADA POR UM FURO DE POçO. Métodos e sistemas para a realização de testes de uma formação subterrânea penetrada por um furo de poço sao providos. Uma ferramenta de realização de testes tem uma pluralidade de obturadores espaçados entre si ao longo do eixo da ferramenta, e pelo menos uma porta de realização de testes. A ferramenta de realização de testes é posicionada no interior do furo de poço e os obturadores são estendidos no sentido de engajamento vedante com as paredes do furo de poço, vedando desse modo um intervalo do furo de poço. Em algumas modalidades, o intervalo do furo de poço vedado entre dois obturadores é ajustado ao longo da extensão do furo. Numa modalidade, a posição da porta de realização de testes está ajustada entre dois obturadores. Os métodos podem ser usados para reduzir de modo proveitoso a contaminação do fluido da formação por meio dos fluidos ou fragmentos no furo de poço.
