    Abstract: A differential pressure indicator (DPI) for use with a downhole isolation valve includes a tubular mandrel for assembly as part of a casing string and for receiving a tubular string. The mandrel has a stop shoulder and a piston shoulder. The DPI further includes a tubular housing for assembly as part of the casing string and for receiving the tubular string. The housing is movable relative to the mandrel between an extended position and a retracted position and has a stop shoulder and a piston shoulder. The DPI further includes a hydraulic chamber formed between the piston shoulders and a coupling in communication with the hydraulic chamber and for connection to a sensing line. The housing is movable relative to the mandrel and to the extended position in response to tension exerted on the DPI.

    Abstract: Resumo “indicador de diferencial de pressão, sistema para uso quando da perfuração de um orifício de poço, método para a construção de um orifício de poço e válvula de isolamento” um indicador de diferencial de pressão (dpi) para uso com uma válvula de isolamento de um poço inclui um mandril tubular para a montagem como uma parte de uma coluna de revestimento e para receber uma coluna tubular. O mandril tem um ombro de batente e um ombro de pistão. O indicador de diferencial de pressão adicionalmente inclui um alojamento tubular para a montagem como uma parte da coluna de revestimento e para receber a coluna tubular. O alojamento é móvel com relação ao mandril entre uma posição estendida e uma posição retraída e tem um ombro de batente e um ombro de pistão. O indicador de diferencial de pressão adicionalmente inclui uma câmara hidráulica formada entre os ombros de pistão e um acoplamento em comunicação com a câmara hidráulica e para a conexão a uma linha sensor. O alojamento é móvel com relação ao mandril e com relação à posição estendida em resposta à tensão exercida sobre o indicador de diferencial de pressão. ?? ?? ?? ?? 1/1

    Abstract: DIFFERENTIAL PRESSURE INDICATOR FOR DOWNHOLE ISOLATION A differential pressure indicator (DPI) (40) for use with a downhole isolation valve (50) includes a tubular mandrel (41m) for assembly as part of a casing string (11) and for receiving a tubular string (5). The mandrel (41m) has a stop shoulder (42h) and a piston shoulder (43p). The DPI (40) further includes a tubular housing (41h) for assembly as part of the casing string (11) and for receiving the tubular string (5). The housing (41h) is movable relative to the mandrel (41m) between an extended position and a retracted position and has a stop shoulder (44h) and a piston shoulder (44p). The DPI (40) further includes a hydraulic chamber (46c) formed between the piston shoulders (43p, 44p) and a coupling (46c) in communication with the hydraulic chamber (46c) and for connection to a sensing line (37s). The housing (41h) is movable relative to the mandrel (41m) and to the extended position in response to tension exerted on the DPI (40). ________________ -3/6 _ _ _ _ _ _ _ _ 46f 44 u 4 7a 42 41 m 42h 4 44h 43u4m 44 44p 444 7b 43p, -61 46c 41 h if 47c 43m 44b 45 44s 43s 45u 43b 47d __ _ _ _ _ _ _ _ _ _ __ _ _ _ _ _ _ _ _ _ _ 45h 45b 47e
